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 7,763 (2018) and Lovelock, 33 miles southwest, with a population of 1,814 (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 estimate has been converted into metric tonnes from short tons using a factor of 0.9072.
- Mineral reserves are reported at the point of delivery to the process plant, using the 2014 CIM Definition Standards, with an effective date of December 31, 2023. The qualified person as defined under National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“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 US$1,800/oz considering only oxide material; gold recoveries varied by deposit and ore type, ranging from 45% to 64%; reference mining cost of $2.74/t mined in-situ and $2.08/t mined fill; processing cost of $4.97/t processed for oxide crushed material and $2.67/t for oxide run-of-mine (“ROM”) material; G&A costs of $1.20/t ore processed; treatment and refining costs of $6.57/oz gold recoverable; royalty costs of $88.00/oz gold recoverable; and pit slope inter-ramp angles ranged from 38–42° for rock and 30° for alluvium / fill.
- Mineral reserves are reported at a cut-off grade ranging from 0.13 g/t to 0.20 g/t.
- Mineral reserves include a stockpile of 1,934 kt at an average grade of 0.19 g/t and total contained gold of 11.57 koz.
- Mineral reserves include Heap Leach Inventory of 3,548 kt at an average grade of 0.29 g/t and total contained gold of 32.58 koz.
- Numbers have been rounded and may not sum.
Notes to Mineral Resources
- Mineral resources estimate has been converted into metric tonnes from short tons using a factor of 0.9072.
- Mineral resources are reported, using the 2014 CIM Definition Standards, with an effective date of December 31, 2023. 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 US$1,800/oz; gold recoveries ranging from 45% to 64% for oxides and 80% for sulfides; reference mining cost of $2.74/t mined in-situ and $2.08/t mined fill; processing cost of $4.97/t processed for oxide crushed material and $2.67/t processed for oxide ROM material; processing cost of $23.15/t processed for sulfide material; general and administrative costs of $1.20/t processed; treatment and refining costs of $6.57/oz Au recoverable; royalty of $88.00/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 0.20 g/t for oxides and is 0.56 g/t for sulfides.
- Mineral resources include a stockpile of 1,934 kt at an average grade of 0.19 g/t and total contained gold of 11.57 koz.
- Mineral resources include Heap Leach Inventory of 3,548 kt at an average grade of 0.29 g/t and total contained gold of 32.58 koz.
- Numbers have been rounded and may not sum.
To the best of Integra Resources Corp.’s knowledge, information and belief, there is no new material scientific or technical information that would make the disclosure of the mineral resources or mineral reserves included in the Florida Canyon Report inaccurate or misleading” under the R&R statement for Florida Canyon.
