Increased Reserves And Extension Of Mine Life At Aurizona And Castle Mountain
VANCOUVER - Equinox Gold Corp. CEO, Christian Milau, said, “The Company’s 2021 results demonstrate consistent year-on-year production and cash flow growth as the Company advances toward its target of achieving more than one million ounces of annual gold production. During 2021, our seven operating mines produced 602,110 ounces of gold and generated operating cash flow of $256 million, compared to 2020 production of 477,200 ounces of gold and $321 million in operating cash flow. We realized more than $1 billion in revenue for the year, and produced our millionth ounce of gold, both important milestones for our growing company. We achieved significant reserve and resource growth, adding more than three million ounces of gold reserves to our portfolio through the acquisition of Premier Gold and its Greenstone project. We also increased mineral reserves and demonstrated mine life extension at Aurizona and Castle Mountain, and drilled more than 219,000 meters across the portfolio. The next few years will be focused on delivering organic growth from our pipeline of development and expansion projects, which will collectively add more than 600,000 ounces of annual production to the Company at reduced costs."
For 2022, the Company expects to achieve its fourth consecutive year of production growth with guidance of 625,000 to 710,000 ounces of gold, which is an increase of 11% compared to 2021 production (using the mid-point of 2022 guidance). Cash costs for 2022 are estimated at $1,080 to $1,140 per oz, with AISC of $1,330 to $1,415 per oz. Production and cost guidance excludes Mercedes as the previously announced sale to Bear Creek is expected to close around the end of Q1 2022, although ounces produced and capital spent prior to closing will be attributable to Equinox Gold. The Company may revise guidance during the year to reflect changes to expected results.
Production is expected to increase quarter over quarter, with 60% of gold production and more than 85% of operating cash flow anticipated in the second half of the year. As production increases, AISC is expected to decrease.
The Mesquite production for 2022 is estimated at 120,000 to 130,000 ounces of gold, with approximately 60% of production expected in the second half of the year. Ore from the Brownie pit is expected to be the primary source of production during 2022. Completion of the Brownie strip campaign provided full access to oxide ore at the bottom of the Phase 1 Brownie pit, and stripping of the Brownie Phase 2 pit commenced in Q4 2021. Forecast AISC at Mesquite in 2022 includes estimated sustaining capital of $52 million related primarily to a $44 million stripping program commencing in Q1 2022 to open up a new phase of the VE pit, which is expected to be the primary source of ore in Q4 2022 and into 2023. Non-sustaining growth capital of $20 million includes $5 million for exploration with the objective of converting resources to reserves in the Brownie, VE and Rainbow pits. The Company is also permitting and planning the construction of extensions to the leach pad and expects to make $12 million in lease payments for the truck fleet.
Castle Mountain, in California, reported production for 2022 is estimated at 25,000 to 35,000 ounces of gold with cash costs of $1,150 to $1,200 per oz and AISC of $1,475 to $1,525 per oz.
The Los Filos Gold Mine in Guerrero, Mexico production for 2022 is estimated at 160,000 to 180,000 ounces of gold. While Los Filos' costs are expected to be lower in the second half of the year, waste stripping campaigns in the Los Filos and Guadalupe open pits and underground development for Bermejal are expected to impact AISC and free cash flow for the year. The Company continues to review the potential to construct a new carbon-in-leach plant to operate concurrently with the existing heap leach operation, which could increase production and lower costs, but does not expect to make a construction decision until the majority of Greenstone expenditures are complete and the current stability with local communities allows operations to continue without interruption.
Capital investments at Los Filos during 2022 are expected to focus primarily on open-pit stripping and underground development, with almost $30 million of expenditures carried over from 2021. AISC at Los Filos in 2022 includes $38 million of sustaining capital, with $13 million allocated for capitalized stripping of the Guadalupe open pit, $7 million for development of the Los Filos underground mine, $10 million for fleet refurbishment and processing equipment and $4 million for exploration.
Aurizona production for 2022 is estimated at 120,000 to 130,000 ounces of gold. Production during 2022 is expected to come from multiple ore sources, including Piaba East and the new Boa Esperança pit, which was opened up with a small stripping campaign during 2021. The Company expects to continue to advance the Aurizona expansion during 2022, with plans to initiate permitting for an exploration portal, undertake some underground-focused exploration and continue internal studies. Development work to access the underground deposit could begin in late 2022.
Fazenda's production for 2022 is estimated at 60,000 to 65,000 ounces of gold, with cash costs estimated at $975 to $1,025 per oz and AISC estimated at $1,200 to $1,250 per oz.
Of the $14 million sustaining capital investment planned for 2022, $6 million is allocated for underground development, $3 million for open-pit waste stripping, $2 million for exploration to upgrade inferred Mineral Resources and $2 million for engineering, plant maintenance and equipment. Non-sustaining growth capital of $11 million includes $4 million for underground development and $3 million for exploration. In addition, the Company has planned a significant regional exploration program in the Fazenda-Santa Luz district, a 70-km-long greenstone belt that hosts both the Fazenda and Santa Luz mines. The 2022 regional exploration program includes a $1.5 million airborne geophysical survey that will cover the entire belt and is expected to greatly aid in the development of new targets and more than 50,000 meters of drilling targeting high priority near-mine and regional targets. Of the total $9 million non-sustaining capital spend, $4 million has been budgeted to Fazenda with the remainder budgeted to Santa Luz.
RDM production is expected to increase almost 30% compared to 2021 as the result of modifications to the pit design based on a new geotechnical model. Production for 2022 is estimated at 70,000 to 80,000 ounces of gold.
