The Florida Canyon Mine is located 125 miles east of Reno Nevada, and immediately south of Interstate 80. The nearest towns are Winnemucca, 40 miles northeast with a population of 8,388 (2022) and Lovelock, 33 miles southwest, with a population of 1,854 (2018). The highway exit for the Florida Canyon Mine from I-80 is at Imlay, Nevada. Access is reliable via the Interstate year round.
The mine currently produces gold by conventional hard rock open pit mining with processing by 2 stage crushing and Run of Mine (ROM) heap leaching. The mine was in continuous operation from 1986 through 2011 and then intermittently until 2015. It was reopened in mid-2016 and has been in operation since that time. The land package owned or leased by FCMI covers a total of 22,039.9 acres. Fee lands total 5,520.4 acres and 789 unpatented claims total 16,159.6 acres. Contained within the fee lands are 19 patented claims totaling 359.9 acres. This land position includes both Florida Canyon and the Standard Mine, which is located south of Florida Canyon.
Mineral Reserves & Resources

Notes to Mineral Reserves
- Mineral reserves are reported at the point of delivery to the process plant, using the 2014 CIM Definition Standards, with an effective date of May 31, 2026. The qualified person as defined under NI 43-101 for the estimate is Ms. Terre Lane, MMSA QP, a Global Resource Engineering, Ltd. employee.
- Mineral reserves are constrained within an open pit design that uses the following assumptions: gold price of $2,400/oz considering only oxide material; gold recoveries varied by deposit and ore type, ranging from 43% to 67%; reference mining cost of $3.24/t mined in-situ and $2.93/t mined fill; processing cost of $6.51/t processed for oxide crushed material and $4.23/t for oxide run-of-mine (“ROM”) material; G&A costs of $1.14/t ore processed; treatment and refining costs of $38.73/oz gold recoverable; royalty costs of $132.00/oz gold recoverable; and pit slope inter-ramp angles ranged from 36–42° for rock and 36° for alluvium / fill.
- Mineral reserves are reported at a cut-off grade ranging from 0.14 g/t to 0.15 g/t.
- Mineral Reserves include a stockpile of 1,094 kt at an average grade of 0.21 g/t and total contained gold of 6.78 Koz.
- Mineral Reserves include Heap Leach Inventory of 6,648 kt at an average grade of 0.29 g/t and total contained gold of 56.5 Koz.
- Numbers have been rounded and may not sum.
Notes to Mineral Resources
- Mineral resources are reported, using the 2014 CIM Definition Standards, with an effective date of May 31, 2026. The qualified person as defined under NI 43-101 for the estimate is Ms. Terre Lane, MMSA QP, a Global Resource Engineering, Ltd. employee.
- Mineral resources are reported inclusive of those mineral resources converted to mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
- Mineral resources are constrained within a conceptual open pit shell that uses the following assumptions: gold price of $2,650/oz; gold recoveries ranging from 43% to 67% for oxides and 80% for sulfides; reference mining cost of $2.79/t mined in-situ and $2.47/t mined fill; processing cost of $6.51/t processed for oxide crushed material and $4.23/t processed for oxide ROM material; processing cost of $26.30/t processed for sulfide material; general and administrative costs of $1.14/t processed; treatment and refining costs of 38.73/oz Au recoverable; royalty of $132.00/oz Au recoverable, and pit slope overall angles ranging from 30–36°.
- Mineral resources are reported at a cut-off grade ranging from 0.13 g/t to 0.14 g/t for oxides and is 0.46 g/t for sulfides.
- Mineral Resources include a stockpile of 1,094 kt at an average grade of 0.21 g/t and total contained gold of 6.78 Koz.
- Mineral Resources include Heap Leach Inventory of 6,648 kt at an average grade of 0.29 g/t and total contained gold of 56.5 Koz.
- Numbers have been rounded and may not sum.
NOTES FOR STANDARD MINE
- Mineral Resources are reported, using the 2014 CIM Definition Standards, with an effective date of May 31, 2026. The Qualified Person for the estimate is Mr. Antoine Teixeira deCarvalho, P.Geo., a BTAMS employee.
- Mineral Resources are reported inclusive of those Mineral Resources converted to Mineral Reserves. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
- Mineral Resources are constrained within a conceptual open pit shell that uses the following assumptions: gold price of US$2,650/oz; gold recoveries ranging from 43% to 66.7% for oxides and 80% for sulfides; reference mining cost of $2.79/ton mined in-situ and $2.47/ton mined fill; processing cost of $5.37/ton processed for oxide crushed material and $3.09/ton processed for oxide ROM material; processing cost of $25.16/ton processed for sulfide material; general and administrative costs of $1.14/ton processed; treatment and refining costs of $38.73/oz Au recoverable; royalty of $145.75/oz Au recoverable, and pit slope overall angles ranging from 30–43°.
- Mineral Resources are reported at a cut-off grade ranging from 0.0038 oz/ton to 0.0071 oz/ton for oxides and is 0.0133 oz/ton for sulfides.
