DOVE Ball mills, also known as Grinding mill, Mining mill, Pebble mill, Ball & Pebble mill, is an important machinery in the mining and various other industries, which would require grinding different material.

They are highly efficient Grinding mill machines, designed for grinding applications, where fine material is required. DOVE Ball Mills are used in supplied and applicable for wet and dry grinding applications within the following branches of industries:

DOVE ball mills is a rotating horizontal cylinder that tumbles the material to grind with a certain media. The standard media that we use in our ball milling process are the steel grinding balls, however depending on the specific application, we can configure the grinding mill with different media.

DOVE supplies various types and sizes of Ball Mill Balls, including; Cast Iron steel Balls, Forged grinding steel balls, High Chrome cast steel bars, with surface hardness of 60-68 HRC. DOVE Ball Mills achieves size reduction by impact and attrition. When the cylinder rotates, the balls are dragged to almost the top of the shell, and from there, they fall unto the material, which lead to the material breaking due to the impact.

DOVE Ball Mills are used in hard rock mineral processing plants as an ore-dressing step to grind the rocks into fine powder size, liberating the mineral particles from the rocks. This will ensure that the ore is well prepared for the next stage of processing and optimize the recovery of the minerals.

DOVE ball mill is integrated and used in DOVE Portable and Semi-Stationary Hard Rock plants (Hard Rock processing plants) to efficiently grind the ore from primary deposit until the liberation size of valuable minerals is reached. DOVE ball mill is the key grinding equipment after material is crushed. It is used to grind and blend bulk material into powder form using different sized balls. The working principle is simple, impact and attrition size reduction take place as the ball drops from near the top of the rotating hollow cylindrical shell of the Ball Mill. The output materials will be feed to the processing and recovery machines.

DOVE Ball Mills are deigned for either wet or dry grinding of materials, in various models, and in accordance to the processing and the crushing plant design, to cater to the liberation size of the minerals and the hardness of the ore.

DOVE supplies two different kinds of ball mills Grate type, and Overfall type. The difference between the two type is according to their ways of discharging material, and the plant flow design specifications.

The Grinding Balls will grind the material into powder size of 20 to 75 micron. In mining operations, this will allow for the liberation of gold and other precious metals that are hosted by the rocks. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties, specification and advantages.

Media Size: The grinding media particles should be substantially larger than the largest pieces of final material after grinding. The smaller the media particles, the smaller the particle size of the final product.

Composition: Each ball mill application has different requirements. Some of these requirements are relates to the grinding media being in the finished product, while others are based on how the media will react with the material being milled. Therefor, grinding media selection plays major factor on the final milled product.

Contamination: In certain grinding mill process, low contamination is important, the grinding media may be selected for ease of separation from the finished product, for example steel dust produced from steel balls can be magnetically separated from non-ferrous products. An alternative to separation is to use media of the same material as the product being milled.

Corrosive:Certain type of media, such as steel balls, may react with corrosive materials. For this reason, stainless steel balls, or ceramic balls, and flint grinding media may each be used when corrosive substances are present during grinding.

resource global network | telson mining corporation

Telson MiningCorpis a Mexico-focused public company listed on the TSX Venture Exchange (TSXV) that was formed by current CEO Ralph Shearing and a colleague and close friend in the late 1990s. Not long after its founding, the nascent firm discovered thepolymetallicTahuehuetoProject inthe prolific Sierra Madre Mineral Beltwithin the state of Durango.Telson hasgone on to retaintheprojectto this day, advancing it through several cycles in the commodities sector. The company started to substantially explore theTahuehuetoconcessions during the mining boom of 2004-08 before pulling back during thedecline of 2015-16. Despite the difficult market conditions at that time, Telson managed to attract vital funding from a Mexican mining group in 2015,which allowed the company to complete bulk sampling work and economic studiesthatfirmed up the projects viability and convinced TrafiguraMexicoto provide a loan facility for the construction of the mine. During this period, Telson also came across the Campo Morado Mine inGuerrerostate abase metalsasset that Nyrstar had spent $500 million on but were looking to divest. Telson subsequently acquired the mine for a fee of $20 million in 2017.

Campo Moradowas averygood buyas we were able to quickly get the mineback into production, says Shearing. At the same time,we were building our project in Tahuehueto and the funding plan there required cash from Campo Morado to slide overfor its construction.

Telson soon encountered some difficulties with the Campo Morado asset and had to put the mine into care and maintenance in 2019, which stalled the construction ofTahuehueto.But, after further COVID-19 related disruption earlier this year, the company is now producing again at Campo Morado and moving full steam aheadto securefinalfunding to completeconstruction atTahuehueto.

We have a very good operations team in Mexico, that group came in and funded usfive years ago, andwe have a good blend of professionalsin mining and capital markets. Together,we are working very effectively to move things forward.

Tahuehuetoconsists of 28 mining concessions spread across a largeexpanse of prospective groundin the Sierra Madre which hosts a series of historic and producing mines and most of Mexicos active exploration and development projects.

Its recognised as a mineralised district. If you were to compare it to any othermineralised region in Mexico, the one that comes to mind is the San Dimas Mining District, he saysbefore pointing out that San Dimas is about a third larger and has been producing for 150 years,while theTahuehuetodistrict remains underexplored.

Down the years, the region has received less attention than San Dimas due to a perception of its remoteness in Mexico. However, based on Canadian standards, Shearing believes this not to be the case. If I can drive to my project in one day, I dont consider that remote, he remarks.

Telsons exploration campaigns have identified gold-silver and base metals reserves atTahuehueto, including copper,leadand zincin the single structural zone the company has focused its efforts on thus far.

Inside this structural zone, Telson has defined total probable reserves of 3.26 million tonnes (Mt) with average grades of 3.4 g/t gold, 41.8 g/t silver, 0.35% copper, 1.19% lead and 2.24% zinc.At present, gold resembles around 75% of the value of the project and the current grade estimations will make Telson one of the four highest grade producers in Mexico.

Weve really only explored alongthis onemajor structure and haventyetcompleted theexploration and developmentthere. It remainsopen to mineralisation at depthandalong strike in both directions.

In the structuralcorridorwe are working on right now, we think there is likely to be around 7 km of strike length potential and weve explored about 2.4 km on that major structure, says the CEO.There are also seven or eight more mineralised structuresexposed on surface within this corridor. We have to follow up with exploration on all of those as time carries on.

Telson is also developing an underground extension atTahuehuetoand has completed around 90% of the development work for the first three to four years of the operation. That development work hasextendedone tunnelatleast 250 metrespastknown drill holesintercepts, wherecontinuousmineralisationis already adding new resources to the project,not yet quantified in a new NI 43-101 technical report.

Were alreadygrowing the asset with theunderground development, andas soon as the companyisin ahealthierstatewell be able to get drills turning againandbring in new resources and reserves, assures Shearing.

Here he alludes to the difficult market conditions brought about by the COVID-19 pandemic this year, although the company still managed tonegotiatea US$12 million loan facility withAccendoBanco at the height of the global outbreak in June. The deal isexpected to close very soon.

AccendoBanco has even advanced $500,000 of the loan figure to help bring in additional funding and has also helped clean up Telsons balance sheet and paid off some of the debt accumulated at Tahuehueto. At this stage, the bankand bank associateshaveinvestedover $1 millionto propel the project through to the finalfundingstage.

Once the deal reaches full closure, Telson will have the funds available to resumeconstructionandfinishbuildingthe mining operation, which should be completedearly next year according to Shearing.

The company is building a plant with anintendedcapacity of1,000tonnes per day (tpd)and targeting to initiate productionwith one ball millin the 500tpdrange withineightmonths ofsecuring final funding,andthereafterramping up to 1,000tpdonce the second ball mill is installedlater in2021. With over60% ofconstruction already completedthat isanachievabletimelineonce we have the funding in place.

Campo Morado is an underground polymetallic minewitha large resource of 17.6 Mt (includinghigh gradegold, silver, zinc,copperand lead mineralisation) andinfrastructure, installations and equipment capable of processing 2,300tpdof ore.

Although Shearing regards the 2017 acquisition as a good one for Telson, he notes that it has previously been regarded as a difficult asset to operate, predominantly for two reasons: Falling zinc prices and low metallurgical recoveries.

On the latter point, metal grades are relatively high at Campo Moradowith average gold at 1.5 g/t andsilver grades of 90-100 g/tbut recoveries are languishing at around 15% gold and 30-40% silver. However, Telson is currently investigating ways of improving its recovery rates at the mine.

A group out of the UK conductedLeachoxtesting which achieved up to 60% gold recoveries and 80% silver recoveries. This was first phase testing and I have since spoken to the group and they think they can do better on the second phase.

In addition, Telson is looking at improving productivity at the mine by increasing the plant capacity to 3,000tpd, an expansion which had already been started by Nyrstar and is currently 80% complete.

At 3,000tpd,the economiesof scale will work to our advantage andcertainlyimprove profitability.At the moment,we are running at 2,100tpdand making money. But with metal prices [including zinc] improving,wellbe able to continually operate the project after some interruptions in the last 12 months.With some hard work andingenuitywe will increase the profitability of the mine.

In a similar vein atTahehueto, the company is planning for a long-termexpansion of the plant towards 3,000tpd, based on adding resources and reserves through exploration,todepth and along strikeon the currentzoneswhere resources and reserves arealreadydefinedin thecompanyscurrent mine plan,as well asexploringalready identifiedvein structuresoutsidethe current mine plan areaand finallyinitiatinggreenfieldsexplorationwithin the overallTahuehueto mineralised district.

Shearingstatesthat both projects contain excellent organic growth potential which will be unlocked when Telson finds itself in a stronger cash position and can subsequently get drills turning again.

The company currently has its hands full with development work schedules at Tahuehueto andCampo Morado, butis also monitoring additional opportunities for external growth via potential acquisitions in Mexico.

In conclusion, Telson is nearing completion of its long-held Tahuehuetohigh gradegoldproject in Durango state, with the final funding solution the last piece of the jigsaw ahead of its construction. Meanwhile, Campo Morado inGuerrerostate is back into production and primed for an expansion which will boost productivity and profitability.

Tahuehueto isan advancedin construction,highgradegold mining project withsilver and base metals, recoveries aregreatand the metallurgy could not be better. Our cash flow models predict very good profitabilityand excellent freecash flowsat Tahuehueto, Shearing asserts

Campo Morado has its difficulties but if we are efficient and tackle it properly, we will be able toincrease recoveriesand throughputproductionto markedly increaseprofitabilityin the future. And there isgreatexploration potential on both projects, soTelsonMining Corporationhas excellent growth potential,buildingtowardsbecominga midtiermining companyin Mexico.

(TSX: AUE / AIM: AUE) (Aureus or the Company) is pleased to announce that it has placed an order for the ball mill for the New Liberty Gold Project (New Liberty or the Project) in Liberia, which is the key plant item as described in its independent technical report dated 1 October 2012. The placement of this order is part of Aureus strategy to source the longerlead key plant items for the New Liberty process plant in sufficient time to facilitate the successful achievement of first gold in December 2014.

An order has been placed with NCP International Ltd (NCP) for the supply, delivery and installation of a ball milling system, which is due for delivery in May 2014. The ball mill has a rating of 145t / hr and is capable of processing at a rate of up to 1.1Mtpa of ore. The civil foundations will have been completed by the time of delivery, ready for the erection and assembly of the mill and supporting equipment. The mill is a critical component in the commissioning process and pre-commissioning checks on the mill are scheduled to be carried out in October 2014, with first gold production on track for December 2014.

We continue to make significant progress on the development and construction of New Liberty. The ordering of the ball mill is another critical step to ensure the timely and successful development of the Project. The placing of the mill order is an exciting step for Aureus, as the mill is the heart of our new process plant. We are pleased to be associated with NCP, which brings many years of milling experience to the Project.

As a consequence of having all permits in place, key management personnel, an owner team assembled and project debt financing process in place, Aureus continues to de-risk the Project and is well placed to achieve first gold by December 2014.

The Companys assets include the New Liberty gold deposit in Liberia (the New Liberty Gold Project or the Project), which has an estimated proven and probable reserve of 910,000 ounces of gold grading 3.3 g/t and an estimated measured and indicated mineral resource of 1,143,000 ounces of gold grading 3.6 g/t and an estimated inferred mineral resource of 593,000 ounces of gold grading 3.2 g/t. A feasibility study has been completed on the Project and construction has commenced with initial earthworks. The Project is expected to have an eight and a half year mine life and annual production of 120,000 ounces for the first five years of production. The Company has financed the Projects equity funding requirement and is in advanced discussions with interested parties to fund the balance.

The New Liberty Gold Project is located within the Bea Mountain mining licence, which covers 457 km and has a 25 year, renewable, mineral development agreement. The Bea Mountain mining license also hosts the proximal gold targets of Ndablama, Gondoja and Weaju, which are the focus of exploration programs during 2013.

How many types of ball mill 1. Based on the axial orientation a. Horizontal ball mill. It is the most common type supplied from ball mill manufacturers in China. Although the capacity, specification, and structure may vary from every supplier, they are basically shaped like a cylinder with a drum inside its chamber. As the name implies, it comes in a longer and thinner shape form that vertical ball mills. Most horizontal ball mills have timers that shut down automatically when the material is fully processed. b. Vertical ball mills are not very commonly used in industries owing to its capacity limitation and specific structure. Vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum, that is the vertical grinding mill only produced base on custom requirements by vertical ball mill manufacturers. 2. Base on the loading capacity Ball mill manufacturers in China design different ball mill sizes to meet the customers from various sectors of the public administration, such as colleges and universities, metallurgical institutes, and mines. a. Industrial ball mills. They are applied in the manufacturing factories, where they need them to grind a huge amount of material into specific particles, and alway interlink with other equipment like feeder, vibrating screen. Such as ball mill for mining, ceramic industry, cement grinding. b. Planetary Ball Mills, small ball mill. They are intended for usage in the testing laboratory, usually come in the form of vertical structure, has a small chamber and small loading capacity. Ball mill for sale In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment. Over a period of many years development, the fine grinding fineness have been reduced many times, and the ball mill machine has become the widest used grinding machine in various applications due to solid structure, and low operation cost. The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as for dry materials process, the shell dustproof to minimize the dust pollution. Gear drive mill barrel tumbles iron or steel balls with the ore at a speed. Usually, the balls filling rate about 40%, the mill balls size are initially 3080 cm diameter but gradually wore away as the ore was ground. In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity. JXSC ball mill manufacturer has industrial ball mill and small ball mill for sale, power range 18.5-800KW. During the production process, the ball grinding machine may be called cement mill, limestone ball mill, sand mill, coal mill, pebble mill, rotary ball mill, wet grinding mill, etc. JXSC ball mills are designed for high capacity long service, good quality match Metso ball mill. Grinding media Grinding balls for mining usually adopt wet grinding ball mills, mostly manganese, steel, lead balls. Ceramic balls for ball mill often seen in the laboratory. Types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc. The ball mill barrel is filled with powder and milling media, the powder can reduce the balls falling impact, but if the power too much that may cause balls to stick to the container side. Along with the rotational force, the crushing action mill the power, so, it is essential to ensure that there is enough space for media to tumble effectively. How does ball mill work The material fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls rises and falls follow the drum rotation direction, the grinding media be lifted to a certain height and then fall back into the cylinder and onto the material to be ground. The rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding result. Based on experience, the rotat

ion is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and dont fall. In summary, it depends on the mill diameter, the larger the diameter, the slower the rotation (the suitable rotation speed adjusted before delivery). What is critical speed of ball mill? The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75% of critical speed. What is the ball mill price? There are many factors affects the ball mill cost, for quicker quotations, kindly let me know the following basic information. (1) Application, what is the grinding material? (2) required capacity, feeding and discharge size (3) dry or wet grinding (4) single machine or complete processing plant, etc.

what is ball mill | how many types of ball mills | m&c

Ball mill is a very important mineral grading equipment, which is indispensable for mineral processing, building materials, metallurgy and chemical industry. With the need of market, a variety of different types of ball mills have emerged. According to different standards, there are many types of ball mills.

1. Short Cylinder Ball Mill: The ball mill with the cylinder length (L) less than 2 times of the cylinder diameter, i.e. the ball mill with L 2D is short cylinder ball mill, which is usually of single bin structure, mainly used for rough grinding or primary grinding operation, and can realize the wide use of 2-3 ball mills in series.

3. Gravel Mill: The grinding medium mainly includes pebble, gravel, sand, porcelain ball, etc. Most of the gravel mills use porcelain or granite as lining plates, which are widely used in the production of color cement, white cement, ceramics and other fields.

1. Tail Discharge Mill: The head and tail of tail discharge mill are used as the inlet and outlet of materials. When the mill is working, the material is fed from the inlet end and discharged from the other end.

2. Middle Discharge Mill: The inlet of the middle discharge mill is at both ends, and the outlet is in the middle of the mill. Generally, materials are fed from both ends and then discharged from the middle of the cylinder.

1. Center Drive Ball Mill: The drive power device is in the center of the fuselage, and the motor realizes the operation of the ball mill through the reducer. In operation, the hollow shaft in the center of the ball mill drives the grinding body to rotate under the drive of the power system.

1. Wet Type Ball Mill: Water is added at the same time of feeding, and the material is discharged into a certain concentration of slurry. In the closed-circuit system, it forms a closed-circuit operation with the hydraulic grading equipment.

1. Vertical Ball Mill: The vertical ball mill is a new type of ball mill which places the cylinder upright. Through a large number of experiments, it is found that the vertical ball mill has the advantages of high grinding efficiency, low energy consumption and low noise.

2. Horizontal Ball Mill: The horizontal ball mill is used for grinding and dispersing under the closed condition to prevent solvent volatilization. It is especially suitable for fine grinding and mixing of high-purity materials.

Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ore processing system.

Our ball mills are industrial grade and designed for continuous operation, equipped with oversize roller bearings and a complete drive system. All wear parts are highly abrasion resistant and replaceable.

The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. Establishing a commercial liberation size is critical when designing and engineering your grinding circuit.

We bought a turn-key ore processing system that included a hammer mill. The equipment did exactly what it was promoted to do and more. The combination of the jaw crusher with the hammer mill and shaker table did has good if not better than it was advertised by MBMM. I Read More

mining news

VANCOUVER, British Columbia--(BUSINESS WIRE)--Black Dragon Gold Corp. (ASX/TSX-V: BDG) ("Black Dragon" or the "Company")is pleased to announce the positive results of the Preliminary Economic Assessment ("PEA") completed on its 100% owned Salave Gold Project ("Salave" or "Project") located in Asturias in northern Spain. The PEA is based on the recently completed Mineral Resource Estimate completed by CSA Global (See October 25, 2018 News Release). All figures are in United States Dollars unless otherwise stated.

"The completion of the PEA is a major milestone on the path to development of the Salave Project and the metrics support our belief that Salave can potentially generate strong returns for shareholders. It forms the first step in our permitting process, presenting a new optimised process on a zero- discharge basis that minimises the visual and surface impact of the project.

The robust results of this PEA underline the potential economic viability of the current Salave resource to be mined over an initial 14 year mine life, and our successful drilling campaign last year indicates strong potential for growth in mine life at Salave.

This study supports that Salave can produce over 1.1Moz (560 kt of concentrate averaging over 59 g/t Au), providing a number of marketing options for export and refining, minimising the need for additional plant and equipment, and hence reducing the Projects footprint. The relatively low upfront capex also opens alternative financing opportunities which will ensure that both shareholders and the local community benefit from the success of this Project."

An updated NI 43-101 Mineral Resource Estimate, effective 22 October 2018 is included in this PEA and has been filed on SEDAR and the ASX market announcements platform (See October 25, 2018 News Release).

Notes:1. Rounding may cause apparent discrepancies2. Resource Estimate conducted by CSA Global of Perth Australia ("CSA") with an effective date of October 22, 2018. Classification of the MRE was completed based on the guidelines presented by Canadian Institute for Mining (CIM, May 2014), adopted for Technical Reports which adhere to the regulations defined in Canadian NI 43-101. The Mineral Resource Estimate was also prepared in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 edition ("2012 JORC Code").3. The Mineral Resource Estimate was first announced on 25 October 2018. Black Dragon confirms that it is not aware of any new information or data that materially affects the information in the previous announcement and that all material assumptions and technical parameters underpinning the Mineral Resource Estimate continue to apply and have not materially changed.4. A cut-off grade of 2 g/t Au has been applied when reporting the Mineral Resource Estimate.5. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability but do have reasonable prospects for eventual economic extraction.6. The quantity and grade of reported Inferred Resources in this estimation are conceptual in nature and there has been insufficient exploration to define these Inferred Resources as an Indicated or Measured Resource. It is uncertain if further exploration will result in upgrading them to an Indicated or Measured Resource category, although it is reasonably expected that the majority of the Inferred Resources could be upgraded to Indicated Mineral Resources with further exploration.7. The Mineral Resource Estimate underpinning the production targets in this announcement was prepared by a Competent Person under the 2012 JORC Code.8. The title of the report is "Salave Gold Project Mineral Resource Update for Black Dragon Gold Corp.", with an effective date of October 22, 2018, and it was authored by Ian Stockton, B.Sc (Geol)., MAusIMM, FAIG, Dmitry Pertel, MSc (Geol), MAIF, GAA, and Galen White, B.Sc, FAusIMM, FGS.

The mine plan supported by the PEA demonstrates that approximately 81.1% of the total 2018 updated Mineral Resource tonnage is amenable to underground extraction. For purposes of mine planning, the potentially extractable portion of the Mineral Resources are comprised of 9.19 million tonnes at a diluted grade of 3.87 g/t Au, containing just over 1.1 million ounces of gold. The mineralised material modelled to be mined in the PEA contains Mineral Resources classified in the Inferred category (28%) that are too speculative geologically to have economic considerations applied that would enable them to be categorized as Mineral Reserves. These Inferred Resources will require further exploration and definition to meet the criteria to be classified as Indicated or Measured Mineral Resources before being considered for conversion to Mineral Reserves at the next level of detailed economic study.

Given environmental and community considerations, the PEA has only evaluated underground mining operations. The primary mining method selected for detailed analysis in this study was the vertical retreat mining ("VRM"). Sub-level stoping was considered as a secondary method applicable to specific vertical thin geometries (<15m length). Rock and paste fill will be used as backfill to maximize mining recovery.

The mine design was based on basic economic assumptions to create mineable stope outlines. A value of 2 g/t was assumed as mine cut-off grade. Mining dilution and mineralised material loss factors were also applied to each mining shape to reflect the selected mining method.

The mine production rate targets a 0.70 Mtpa of RoM. A conceptual mine layout was designed including stopes and development as illustrated in Figure 1, with 60m levels and 3 x 20m sub-levels. The total mineralised material from stopes, drives and sill pillar recovery (50%) will total 9.2Mt at 3.87 g/t Au.

In order to minimise potential social and environmental issues, processing of Salave mineralised material has been limited to crushing, grinding and flotation, with concentrates exported via local ports. Mine feed will be crushed on surface at a rate of 0.7 Mtpa, and then be processed via conventional SAG and ball milling followed by sulphide flotation and thickening.

Based on flotation test work conducted to date, it is assumed that 97% of the gold head grade will be recovered in the flotation concentrate that will be thickened, filtered and bagged for shipping to customers.

Power to the project is available from Tapia, which is linked to the Asturias main distribution grid, and an existing network of power lines enter the property that are connected to the Spanish national transmission grid. Water for both domestic and plant usage can be sourced from wells, the Porcia River (2.5km east of the property) or the reticulated water supply that is currently in place near the plant location.

A Tailings Management Facility ("TMF") will be constructed at surface for temporary storage of plant tailings. The paste and backfill of the mine will minimise the amount of tailings storage at surface, and various options for complete tailings disposal are being evaluated. The TMF design will involve water recovery in the processing plant and transportation to geo-membrane lined facility eliminating any risk for potential surface and ground water contamination.

Surface facilities to support the Salave Project will include an administration and engineering building, security, warehouse, fuel and explosive storage, fire protection, maintenance shops with a site design to accommodate for 50 full time staff.

The information in this announcement that relates to the PEA for the Salave Gold Project is based on and fairly represents information and supporting documentation prepared by CRS Ingenieria and CSA Global. Paulo Laymen (P.Eng., M.AusIMM., B.Eng., M.Eng.) of CRS Ingenieria supervised the preparation of the PEA, is independent of the Company and a qualified person as defined by National Instrument 43-101 and has reviewed and approved the technical disclosure reported herein. Dmitry Pertel (P.Geo., MSc (Geol), MAIF, GAA) and Belinda van Lente (P.Geo.) of CSA Global were responsible for the Mineral Resource Estimate and are independent of the Company and qualified persons as defined by National Instrument 43-101 and have reviewed and approved the technical disclosure reported herein.

Black Dragon Gold "BDG" is the 100% owner of one of the largest undeveloped gold projects in Europe, the Salave project. Salave is situated in the North of Spain in the province of Asturias. The Salave project has an updated combined Measured and Indicated Mineral Resource of 8.21 million tonnes grading 4.58 g/t Au, containing 1.21 million ounces of gold, plus Inferred resources totalling 3.12 million tonnes grading 3.47 g/t Au, containing 348,000 ounces of gold.

A full technical report summarizing the Mineral Resource estimate completed by CSA Global is available on the companys web site and posted on SEDAR. In addition to the current Mineral Resource, historical exploration work suggests there is the potential for additional mineralisation within Black Dragons landholdings.

equinox gold begins mining at santa luz, construction on track to pour first gold in q1 2022

VANCOUVER, BC, June 29, 2021 /CNW/ - Equinox Gold Corp. (TSX: EQX) (NYSE American: EQX) ("Equinox Gold" or the "Company") is pleased to announce that mining activities are underway at its new Santa Luz Gold Mine in Brazil ("Santa Luz"). Construction remains on track to commence commissioning in Q4 2021 and pour gold in Q1 2022, with the expectation of producing 110,000 ounces of gold annually for the first five years of operations.

Mining is underway to prepare for gold production in Q1 2022. The mining contractor, U&M Minerao e Construo S/A ("U&M"), mobilized to site in May and mining commenced in mid-June. Mining activities are currently focused on removing waste from two locations and developing access roads, ramps, dumps and ore storage areas in preparation for a pre-stripping campaign prior to mining ore in late 2021. To make room for mine expansion, U&M is also relocating an existing ore stockpile with an average grade of 0.9 grams of gold per tonne, which will be used for commissioning activities in Q4 2021.

Construction is on schedule and on budget, with approximately $31 million of the $103 million construction budget spent and $70 million committed at the end of June 2021. As a brownfield past-producing mine, the majority of site services and infrastructure is already in place at Santa Luz. Restart activities are focused on refurbishing existing infrastructure, retrofitting the plant to incorporate resin-in-leach processing, installation of additional grinding infrastructure and increasing the storage capacities of the existing tailings and water storage facilities. A significant construction milestone was achieved on June 25 with installation of the first segment of the ball mill.

Pre-conditioning, leach and detoxification circuit is 46% complete: concrete bases are complete, steel structures are being pre-assembled and tank installation is underway, with four tanks out of ten fully erected and four more partially erected
