VANCOUVER, British Columbia, July 16, 2018 (GLOBE NEWSWIRE) -- Equinox Gold Corp. (TSX-V:EQX) (OTC:EQXGF) (“Equinox Gold” or the “Company”) is pleased to announce the results of the prefeasibility study (“PFS”) for its 100% owned Castle Mountain Gold Mine (“Castle Mountain” or the “Project”) located in California, USA. The PFS contemplates a low-cost heap leach gold mine with 3.6 million ounces (“oz”) of gold reserves that will produce 2.8 million oz of gold and generate $865 million in after-tax cash flow over a 16-year mine life.
Castle Mountain will be developed in two phases with annual average gold production of 45,000 oz over the first three years (“Phase 1”) and annual average gold production of 203,000 oz from years 4 to 16 (“Phase 2”). With Measured & Indicated Mineral Resources estimated at 4.3 million oz of gold (inclusive of reserves), Inferred Mineral Resources of 2.2 million oz and additional near-mine mineralization identified with the 2017 exploration program, there remains potential to extend the mine life and increase annual production.
All amounts are in US dollars unless otherwise indicated. Base case economics were calculated using a $1,250/oz gold price. The Company will host a webcast and conference call at 8:00am PT (11:00am ET) on July 17, 2018 to present the PFS results. Further details are provided at the end of this news release.

Christian Milau, CEO of Equinox Gold, stated: “The prefeasibility study contemplates a robust, long-life, high-margin gold mine in an excellent mining jurisdiction that will generate significant gold production and cash flow for Equinox Gold shareholders. Castle Mountain increases the Company’s gold reserves by more than 350% to 4.5 million ounces while significantly increasing future annual gold production. Combined production from the Aurizona and Castle Mountain mines will total almost 200,000 ounces of gold by 2020 and increase to 350,000 ounces, with all-in costs in the lowest quartile of the industry and significant expansion upside from both mines.”
Ross Beaty, Chairman of Equinox Gold, stated: “Castle Mountain is Equinox Gold’s second cornerstone mine that, by itself, will generate more than one billion dollars of pre-tax cash flow at current gold prices. Successful execution of mine development at both Aurizona and Castle Mountain will establish Equinox Gold as a mid-tier gold producer. We have the operating team in place to rapidly advance these mines while our exploration team demonstrates the great geologic potential at both projects to further enhance the value of these assets for our shareholders.”
OVERVIEW
The Castle Mountain Gold Mine, located in San Bernardino County, California, produced more than one million oz of gold as an open-pit heap-leach mine from 1992 to 2004, when production ceased due to low gold prices and the mine was substantially reclaimed. Under the PFS mine plan, Phase 1 of the Project will produce for three years with average annual production of 45,000 oz of gold. Phase 2 production is expected to average 203,000 oz of gold annually for 13 years, for total LOM production of 2.8 million oz. LOM AISC are estimated at $763/oz, which is in the lowest quartile of the industry. The Project demonstrates strong returns with an after-tax NPV5% of $406 million and an after-tax IRR of 20% using the base case gold price of $1,250/oz ($534 million and 25% at $1,350/oz gold price). The Project is expected to generate average annual after-tax net operating cash flow of $83 million with cumulative LOM after-tax net cash flow of $865 million. At $1,350/oz gold, the Project would average more than $96 million in after-tax net operating cash flow annually and generate more than $1 billion in cumulative after-tax net cash flow over the 16-year mine life.

Castle Mountain has the key permits and the water supply required to commence Phase 1 production, with a Conditional Use Permit (“CUP”), Reclamation Plan and a valid Record of Decision (“ROD”) to mine up to 46,600 tonnes per day (“tpd”) of ore plus waste. Phase 1 will consist of a run-of-mine (“ROM”) heap leach operation processing primarily 12,700 tpd of stockpiled ore from previous operations. Phase 2 will increase throughput to 41,000 tpd of ore, of which 2,340 tpd of higher-grade ore will be processed through a milling circuit. The phased ramp-up approach allows the Company to use existing permits to expedite production while completing the feasibility study and permitting for the Phase 2 expansion. While Phase 2 will operate within the existing permitted mine boundary, the increased mining and water extraction rates will require updated permitting for the Project.

Notes: The Mineral Reserve estimate with an effective date of June 29, 2018 is based on the Mineral Resource estimate with an effective date of March 29, 2018 that was prepared by Don Tschabrun, SME RM of Mine Technical Services. The Mineral Reserve was estimated by Global Resource Engineering, LLC with supervision by Terre Lane, MMSA, SME RM. Mineral Reserves are estimated within the final designed pit which is based on the $850/oz pit shell with a gold price of $1,250/oz. The minimum cut-off grade was 0.14 g/t gold and 0.17 g/t gold for Phases 1 and 2, respectively. Average life of mine costs are $1.39/tonne mining, $2.11/tonne processing, and $0.80/tonne processed G&A. The average process recovery was 72.4% for ROM and 94% for Mill/CIL. Tonnes and gold ounces are both reported in millions. Small differences in total tonnage and grade may occur due to rounding. The Mineral Resource estimate is inclusive of Mineral Reserves.
Drilling at Castle Mountain in 2017 identified a new zone of significant near-surface mineralization at the East Ridge target, peripheral to the current resource pit, with grades significantly higher than the current resource grade. Exploration also identified some higher-grade intercepts at depth in the JSLA Pit that could pull the current pit bottom lower and expand the defined resource boundary at depth. Equinox Gold intends to continue drilling at Castle Mountain with the objective of extending the mine life and potentially bringing higher-grade, near-surface mineralization into the mine plan to increase annual production and reduce the LOM strip ratio.
CASTLE MOUNTAIN MINE PLAN
During previous operations, material below 0.5 g/t gold mined from the Oro Belle and Jumbo pits was placed into the JSLA Pit (Figure 1). Phase 1 ore will be sourced primarily from this stockpile of lower-grade material, which will be placed on the heap leach pad in 15-metre lifts at a rate of 12,700 tpd and leached. Average annual production during Phase 1 is estimated at 45,000 oz of gold for total Phase 1 production of 135,000 oz of gold.
Phase 2, treating ore mined from the large Main Trend and South Domes pits (Figure 1), comprises two circuits whereby an average of 38,600 tpd of ore grading between 0.17 g/t gold and 1.3 g/t gold will be placed directly on the ROM heap leach pad and ore above the 1.3 g/t cut-off will be milled and processed via a CIL (carbon-in-leach) circuit at an average rate of 2,400 tpd. Average annual production during Phase 2 is estimated at 203,000 oz of gold for total anticipated production from Phase 2 of 2.7 million oz of gold. The operating plan calls for 5% of the ore tonnes, containing 29% of LOM produced gold, to be processed by CIL.
Metallurgical test work shows average recoveries of 72% for ROM operations and 94% for milling operations, with average LOM recoveries of 79%.
Mine design and preparation of the mining reserves was completed using conventional open-pit design practice. The designs are based on the $850/oz Lerchs-Grosmann optimal pit solution. From that initial pit design, ramp systems were designed and the pits were divided into 14 different laybacks/phases. Mining of the pits was subsequently scheduled to provide the required ore per year in the plan while balancing the waste mining to ensure proper development of the Project.
During the first two years of operations mining will be performed exclusively by a mining contractor. In years 3 and 4 the mining contractor will continue mining and will also assist with pre-stripping operations, which will be primarily undertaken by the Company’s own mining fleet. Contract mining operations will cease by year 5. Grade control will be performed by Castle Mountain personnel throughout the mine life.
It is anticipated that the mining contractor will use a fleet of 85-tonne to 100-tonne capacity rear dump trucks and equivalent class front-end-loaders. The initial owner fleet is expected to comprise 17 180-tonne capacity rear dump trucks and four 425-tonne class excavators. Mining will take place on 6.1-metre (20 foot) benches, with double benching anticipated in waste areas.
Mining costs are estimated at $1.39 per tonne mined over the current LOM.
PROCESSING
Phase 1 processing operations will treat the solutions from the ROM heap leach facility operating in a new ADR (adsorption, desorption and refining) plant capable of treating 400 cubic metres per hour (“m3/hr”) of pregnant solution to produce doré bars.
Phase 2 will require an expansion of the solution handling and ADR plant capacity to receive the additional flow from the increased ROM heap leaching operations and loaded carbon from the CIL plant. The Phase 2 CIL circuit will comprise a three-stage crushing circuit, ball mill, a gravity circuit, a CIL circuit, an Acacia high intensity leach circuit, a cyanide destruction circuit, and a mill fines filtration circuit. The comminution circuit is designed to achieve 80% passing 150 microns. Loaded carbon from the CIL circuit will be treated in ROM desorption and recovery circuits. The expanded plant will have capacity to treat 1,900 m3/hr to produce doré bars.
Processing costs are estimated at $2.11 per tonne treated over the current LOM.
HEAP LEACH PADS
The heap leach pads for both phases will be double synthetic lined using 2.0 mm LLDPE liner with a leak detection and recovery system between the synthetic liners. Spent heap leach ore from prior operations will be used to form a 600 mm drainage layer above the lining system. Ore will be stacked in 15-metre lifts with no inter-lift liners. Heap irrigation, at a nominal rate of 10 l/hr/m2, will be delivered via buried drip lines to reduce evaporative losses of solution. Leaching reagent consumptions are expected to be 0.1 kg/t NaCN and 1.2 kg/t lime.
POWER
Power for Phase 1 operations will be provided from on-site propane generators. Power for Phase 2 operations will be obtained from a substation in the nearby town of Searchlight, Nevada and delivered via a 69kV powerline that will be constructed for Phase 2 operations.
WATER
Phase 1 operations require approximately 23 litres per second (“l/s”) of water that will be provided from existing water wells at the Project. Phase 2 operations require approximately 60 l/s of water that the Company expects to source from existing water wells and from additional nearby water sources.
WASTE DUMPS, BACKFILL & MILL FINES DISPOSAL
Over the LOM, 58% of the mine waste will be placed in waste dumps to the SE and NW of the active mining areas and the 42% balance will be placed as backfill in the Main Trend Pit.
Approximately 10.7 million tonnes of mill fines will be treated to remove cyanide using a Caro’s acid system, filtered, and then dry stacked at the north end of the heap leach pad. The mill fines will be stacked on the same lining system as the ROM heap leach material (double synthetic liner) and isolated from the ROM heap leach material by an intermediate liner on the interface between the ROM material and the fines.
LABOUR AND SUPPLIES
The Project is approximately a 1.3-hour drive south from Las Vegas, Nevada and accessible year-round by paved highways and well-maintained gravel roads. Construction and operations personnel will be stationed in nearby communities without the need for an on-site camp. There is abundant skilled labour in the region and the Project will provide up to 600 jobs during both construction and operations. The Project is located in the southwest United States mining district and a number of major mining suppliers have distribution hubs in the region.
PERMITTING
The Company has maintained its permits in good standing since prior operations ceased and has the key permits required to commence Phase 1 production including a San Bernardino County CUP and a Federal ROD. Certain administrative State permits are required for Phase 1 and are expected to be received in early to mid-2019.
To permit Phase 2, with a higher processing rate, increased water consumption and a larger area of impact, the Company will modify its existing plan of operations and permits. None of the flora and fauna surveys and environmental studies to date have identified material changes to the mine area compared to the area during previous operations. The Company intends to submit its updated mine plan and reclamation plan by mid-2019 with the target of commencing Phase 2 construction upon receipt of permits.
NEXT STEPS & TIMELINES
The Company intends to advance Phase 1 basic engineering with the target of stacking ore on the heap leach pad and commissioning the ADR plant in late 2019. Concurrently, the Company will undertake a feasibility study and permitting to support development of Phase 2. Data collection for Phase 2 permitting is underway. The Company is also in the process of permitting a water well development program.

An “Inferred Mineral Resource” has a great amount of uncertainty as to its existence and as to its economic and legal feasibility. It cannot be assumed that all or any part of an “Inferred Mineral Resource“ will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves. Readers are also cautioned not to assume that all or any part of an “Inferred Mineral Resource” exists or is economically or legally mineable. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” under CIM standards differ in certain respects from the standards of the United States Securities and Exchange Commission.
