Phase 2 will also provide more than 400 jobs during construction and operations and extend the total mine life to more than 20 years. With Phase 1 in operations and Phase 2 permitting underway, Castle Mountain will be a significant economic driver in the region and a long-life cornerstone asset for Equinox Gold."

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. Equinox Gold completed Phase 1 construction in September 2020 with no lost-time injuries and achieved Phase 1 commercial production on November 21, 2020.

The 2021 Feasibility outlines an expansion of the mine that will include a 45,350 t/d ROM heap leach facility and a new 3,200 t/d milling and leach/carbon-in-leach ("CIL") plant for higher grade ore. The existing open pits will ultimately join to become the Main Pit which, with the South Domes Pit, will provide Phase 2 ore.

PROCESS PLANT AND PROJECT INFRASTRUCTURE

Phase 2 will operate within the current approved Mine Permit boundary and existing site infrastructure will be incorporated into Phase 2, including administration buildings, haul roads, solution handling pumps and storage tanks, a carbon-in-column ("CIC") plant, a cyanide receiving and storage area, a lined event pond, a diesel power generation plant and an assay and metallurgical laboratory.

Castle Mountain Overall Site Plan

The Phase 2 heap leach facility will consist of an enlarged heap leach pad, an additional event pond, additional larger solution handling pumps and an additional CIC plant. The new mill facility will consist of a two-stage crushing facility, conveyors, ball mill circuit, gravity concentration, leach and CIL tanks, thickeners, filters and a reagent handling area. Loaded carbon will be processed in a desorption, electrowinning and refinery plant. Additional infrastructure for Phase 2 includes water supply wells, pumps and distribution systems, installation of an electrical transmission line along a previous corridor, an electrical substation, a filtered tailings storage facility, an extension of two waste rock dumps, a truck shop, and various site improvements and upgrades to meet the expanded project needs.

CAPITAL AND OPERATING COSTS

The 2021 Feasibility contemplates a two-year construction timeline. Total initial capital costs are estimated at $389 million, excluding $121 million for a leased mining fleet, or a total of $510 million if the fleet is purchased up front. All economics below are based on the assumption that the mining fleet is purchased up front.

Sustaining capital costs of $147 million are primarily for mine equipment and development of additional stages of the heap leach pad and filtered tailings facilities, plus additional closure costs of $22 million at the end of the mine life.

PHASE 2 EXPANSION MINE PLAN

Phase 2 will be a conventional off-road truck and shovel open-pit mining operation. As outlined in the Transition Plan table below, the 2021 Feasibility contemplates the commencement of Phase 2 pre-strip in Year 4 of the current operations and a transition to operator owned mining services prior to Year 5. Phase 2 mining production will ramp-up in Year 5 with full Phase 2 mining production coinciding with the start of the fully expanded processing facilities, estimated to be at the start of Year 6.

The Phase 2 mine plan outlines nine phases of open-pit mining from five pit areas – JSLA (3 phases), Jumbo, Oro Belle, East Ridge (2 phases) and South Domes (2 phases) – starting with JSLA backfill and moving north, and then to South Domes to complete the operation. The mining sequence of the phases allows for backfilling of waste as the pit reaches final limits.

The Phase 2 mine production schedule delivers 213.4 Mt of ore grading 0.41 g/t gold to the ROM heap leach and 16.1 Mt of ore grading 2.3 g/t gold to the mill. Waste tonnage totaling 581.7 Mt will be placed in the waste rock dumps. The Phase 2 stripping ratio is 2.54:1. Mining costs for Phase 2 are estimated to average $1.93/t mined.

PRODUCTION SCHEDULE

The Phase 2 production schedule shows average annual production of 218,000 oz of gold during the 14-year mine life with an average AISC of $858/oz. After mining ceases, the 2021 Feasibility anticipates two to three years of heap leach rinsing to recover residual ounces, for total production of 3,203,000 oz of gold.

Of the total annual average production of 218,000 oz per year, the mill is expected to produce an average of 79,000 oz of gold per year for total production from the mill of 1,108,000 oz of gold, with average recoveries estimated at 94%. The heap leach pad is expected to produce an average of 139,000 oz of gold per year for 14 years until the end of mine life. Residual leaching and final rinsing will produce another 246,000 ounces over three years, for total Phase 2 production from the heap leach pad of 2,095,000 oz of gold, with average recoveries estimated at 74%, after rinsing.

Castle Mountain Annual Gold Production and AISC

METALLURGY AND PROCESSING

ROM heap leach ore will be stacked in 25 ft (8 m) lifts on the heap leach pad to be leached with a dilute cyanide solution using a drip irrigation system for 80 days. After percolating through the ore, the pregnant solution will flow by gravity to a pregnant solution tank where it is pumped to a 12,000 gallons per minute ("gpm") CIC circuit to recover the gold from solution. The carbon adsorption circuit will consist of two trains of five cascading carbon columns.

Mill ore will be dumped on a storage pad for recovery by a front-end loader and fed to a two-stage crushing plant. A batch gravity concentrator will treat a portion of the grinding circuit circulating load to recover any gravity recoverable gold with the concentrate being processed in a batch intensive leach reactor ("ILR"). Cyclone overflow will flow by gravity to a pre-leach thickener that will thicken the slurry to 45-50% solids.  Thickened slurry will be pumped to a hybrid leach/CIL circuit to extract the gold.

The carbon handling circuit is designed to handle carbon from both the heap leach CIC circuit and the mill-CIL circuit in separate batch processes. The resulting pregnant solution from the carbon handling and ILR circuits will undergo electrowinning and refining to produce gold doré bars. 

Leached slurry from the leach/CIL circuit will report to a cyanide recovery thickener to recycle as much water and cyanide as possible back to the process. Flocculant will be added to aid in settling solids to produce a thickened product at approximately 60% solids, which will be treated in a cyanide destruction process. The final tailings will be pressure filtered and the filter cake at approximately 18% moisture will be hauled to the filtered tailings facility where it will be stacked on the historical heap leach facility and abutted to the expanded heap leach facility, which allows the Company to minimize new land disturbances.

Castle Mountain Process Site Plan

During historical operations from 1991 to 2004, a total of 1.24 million oz of gold was recovered from 32.8 Mt of processed ore at an average grade of 1.47 g/t gold with a combined average recovery of 80% from milled and heap leached ore, and 76% recovery specifically from the heap leach ore. Metallurgical testwork completed from 2015 to 2020 on both heap leach and mill ore samples showed average gold recoveries of 80% to 82% from various column leach tests at different particle sizes, and 94% recovery from leaching milled ore.

Considering lab and historical operating data, the expected heap leach gold recovery is expected to be 67% during Phase 2operations and 74% after final rinsing.

For mill grade ores processed through the mill with gravity concentration and a leach/CIL circuit with 30 hours of retention time, an overall gold recovery of 94% is expected.

WATER

Castle Mountain is in a semi-arid region and will be a net zero discharge facility, with most of the water loss occurring via evaporation from the surface of the heap leach pad and filtered tailings facility. Process water needs for the recovery plant will fluctuate seasonally and make-up water required for the heap leach will change with the amount of evaporation and precipitation each month. Water consumption will be mitigated using low evaporation buried drip emitters, limiting the amount of water retained in ponds with larger evaporative losses, using binders and dust collectors that limit water needs for dust suppression, and by using extensive water recycling in the process. 

Annual water demand for Phase 2 is estimated to range from 1,150 gpm to 1,900 gpm depending on the season.  The current water supply includes three historical wells providing approximately 150 gpm total and two recently installed wells capable of producing approximately 400 gpm total. Additional water for Phase 2 is expected to be extracted from new wells. Recent water exploration has shown very good potential for water both near site and in a neighbouring water basin. Once developed, wells in both areas are expected to produce between 500 and 1,000 gpm of water each. The Phase 2 development plans include the addition of new wells and well pumps in both locations, as well as an overland pipeline and booster pumps to meet the additional water demands.

POWER

A total of 10 MW of power is required for Phase 2 and will be provided by a connection to the grid at an existing substation near Searchlight, Nevada and routed to site via a new transmission line that will use the previous right of way established for the transmission line during historical operations. This will result in the existing diesel generators at site being re-purposed as back-up emergency electrical power.

ROYALTIES

The Project is subject to several royalties payable to different parties, with a total royalty of approximately 4.5%.

PERMITTING

The Castle Mountain Mine is located on both public and private land and historically has been permitted by co-lead agencies, the County of San Bernardino at the state level and the United States Bureau of Land Management ("BLM") at the federal level. Castle Mountain has all permits required to conduct mining for current operations and is permitted to operate within the approved Mine Permit boundary. Phase 2 will operate within the same Mine Permit boundary; however, modifications to mine and reclamation plan elements, including increased land disturbance, mining and water extraction rates, will require updates to existing permits. Phase 2 is expected to require an updated environmental review as well as several new state and federal permits and amendments.

PROJECT DEVELOPMENT

Execution of the Castle Mountain Phase 2 expansion is expected to be completed in several stages including basic engineering or front-end engineering design (FEED), which will progress in parallel with project permitting exercises. Further stages will include detailed engineering, project construction, commissioning and project start-up and ramp-up.

The overall project timeline depends largely on attaining the discretionary operating permits from the BLM and the County of San Bernardino. Development of Phase 2 is anticipated to require an overall timeline of approximately four years from the start of permitting to achieving full expanded operations.

ADDITIONAL OPPORTUNITIES

There is considerable potential to expand Castle Mountain Mineral Resources and Mineral Reserves by exploring gold anomalies identified at East Ridge, East Flats and Egg Hill. In addition, higher gold prices could make it economic to expand the 2021 Feasibility Mineral Reserve pits and ultimately connect the JSLA and South Dome pits.

Equinox Gold is reviewing opportunities that could result in optimized land use as well as initial capital and operating cost savings. The Company has also completed and is assessing a study examining the potential to use solar power at Castle Mountain. Initial results demonstrate the solar plant levelized cost of electricity would be $0.05/kWh, compared to approximately $0.10/kWh when connected to grid electricity, for net savings per year of $1.9 million based on a capital cost of $12.8 million for a 10 MW_AC photovoltaic solar plant providing 40% of the site power requirements.
