Vancouver — A drill program by
The road-accessible project was previously explored by various companies in the 1980s and ’90s, with most of the work focused on the Eagle zone, one of four intrusive-hosted zones identified at Dublin Gulch. Past work included more than 109 diamond drill holes totalling 13,426 metres, and 158 reverse-circulation holes totalling 22,098 metres.
Based on a 1997 feasibility study by a previous operator, the Eagle zone was estimated to host a minable reserve of 50.4 million tonnes averaging 0.93 gram gold per tonne, or about 1.5 million contained oz. The estimate predates National Instrument 43-101.
Late last year, StrataGold commissioned Australia’s Snowden Mining Industry Consultants to review the previous study and prepare an updated resource calculation compliant with NI 43-101.
Based on a cutoff grade of 0.5 gram gold, Snowden confirmed that the Eagle zone contains an indicated resource of 55.2 million tonnes grading 0.93 gram gold (or about 1.65 million oz.) plus an inferred resource of 17.3 million tonnes grading 0.73 gram gold (or 412,000 oz.).
StrataGold views Dublin Gulch as having excellent potential to expand known resources and define new targets. The Eagle zone is open to the west and downdip, and the current 5,500-metre drill program is primarily aimed at testing the western boundary of the zone and boosting gold resources.
The company will also test two high-priority anomalies situated 250 metres and 1,800 metres from the Eagle zone. These targets are named the Steiner and Olive zones, respectively.
StrataGold sees the property as under-explored for intrusive-hosted gold deposits and notes geological similarities to the low-grade Fort Knox gold mine in Alaska. At Dublin Gulch, gold is hosted along the margins and within sheeted quartz veins, shears and fractures within granodiorite and nearby metasediments.
As part of the current program, the company also is defining and prioritizing early-stage targets identified by a major, magnetic induced-polarization survey carried out over the property late last year.
These data will also help the company better understand the main granodiorite intrusion and granodiorite outliers in order to guide ongoing exploration efforts in the region.
StrataGold has several other projects in the Keno Hill mining camp, namely the Lynx and Aurex properties.
