The 2022 drill program at Wildcat consisted of 12 holes totaling approximately 1,250 metres. The program was designed for infill drilling for mineral resource conversion, geotechnical data for pit wall design, metallurgical data (bottle roll and column tests), and to test gold mineralization below the oxidation profile. Phase 1 drilling will support the updated mineral resource and PEA expected to be released following the completion of metallurgical column testing and various mining studies.
Highlights included drillhole WCCD-0006 that returned an intercept of 0.39 g/t oxide gold over 120.2 metres from surface, including ~50 metres of oxidized mineralization below the 2020 NI 43-101 pit shell. Drillhole WCCD-0007 returned an intercept of 0.51 g/t oxide gold over 50.0 metres, including 0.98 g/t oxide gold over 11.3 metres. Drillhole WCCD-0010 returned an intercept of 0.87 g/t oxide gold over 42.7 metres, ~50 metres outside the 2020 NI 43-101 pit shell and 0.20 g/t oxide gold over 15.2 metres.
WCCD-0006 and WCCD-0007 were drilled for metallurgical testing and to confirm the historical drilling grades and continuity. Grades observed aligned with the existing block model and historical drilling.
WCCD-0010 was drilled to gather geotechnical data to test the northern slope of the pit. A new high-grade oxide extension of mineralization was encountered ~50 metres outside the 2020 NI 43-101 pit shell.
Mineralization in WCCD-0006 and WCCD-0010 is primarily composed of oxidized lithic tuffs. Mineralization in WCCD-0007 is composed of oxidized lithic tuffs to a depth of ~35 metres, followed by the granodiorite basement.
The oxidation profile observed in WCCD-0006 and WCCD-0010 is continuous and persists substantially deeper than previously modeled in the 2020 NI 43-101 estimate.
WCCD-0007 was drilled in the central northern part of the pit and presents significant acidic alteration and silicified-breccia, which are excellent indicators of the existence of a larger feeder zone within the granodiorite basement. WCCD-0007 is located ~100 metres south-west of a rhyolitic pipe, potentially controlling part of the mineralization, and could present high-grade mineralization at depth. Phase 2 drilling at Wildcat is expected to be initiated in 2023 and will target the rhyolitic pipes as they are believed to be related to the primary mineralization feeder zones.
Mineralization in WCCD-0006 and WCCD-0007 demonstrates strong grade continuity, no overburden coverage (extremely low strip ratio), and good rock competency for favourable pit slope angles, which are all attractive characteristics for a heap leach operation.
Excluding the high-grade intercepts, the residual grades of WCCD-0006 and WCCD-0007 are 0.35 g/t gold over 105.2 metres and 0.37 g/t gold over 38.6 metres, respectively, which are both above the cut-off grade of 0.15 g/t gold.
Drilling for the Phase 1 program at Wildcat is now complete and core from the remaining drillholes has been cut and sent to the lab. Final assay data will be communicated to the market as soon as results become available.
Jason Kosec, President, CEO & Director, stated, “We are pleased with the continued success from Phase 1 drilling at Wildcat. Results from WCCD-0006 and WCCD-0007 demonstrate excellent grade continuity which continues to support robust resource conversion that will be demonstrated in the updated mineral resource. The oxidation profile observed is significantly deeper than previously modeled (primarily from RC holes) which is very exciting to see. In addition, WCCD-0010 unexpectedly intercepted high-grade oxide mineralization north of the proposed limit of the pit, further demonstrating the significant growth potential at Wildcat.”
Wildcat is located within the Farrell mining district in Nevada, 56 km north of Lovelock within Pershing County. The property can be accessed by year-round roads from Lovelock via State Route 399 and Seven Troughs Road. The 17,612-acre land package consists of 916 unpatented claims and 4 patented claims.
The Inferred mineral resource estimate at Wildcat contains 776,000 ounces of gold (oxide) (60.8 million tonnes at 0.40 g/t gold.
