Major Developments at Grey Fox Gold Project
Toronto-based McEwen Mining Inc. (NYSE: MUX) has achieved an impressive milestone at its Grey Fox gold deposit, reporting a remarkable increase in estimated gold resources. As of the recent assessment, the indicated resources have surged to 1,538,000 ounces of gold, a substantial increase of 32% compared to past estimates. Furthermore, the inferred resources experienced a significant boost of 95%, reaching a total of 458,000 ounces of gold.
Understanding the Grey Fox Deposit
The Grey Fox deposit is strategically located near McEwen Mining’s Black Fox Mine, playing a crucial role in bolstering the company's overall mining operation. It encompasses six distinct zones: Contact, 147, 147 NE, Grey Fox South (GFS), Gibson, and Whiskey-Jack (WJ). These zones have shown promise, showcasing historical mining potential and favorable geological conditions.
Exploration Results and Insights
Recent exploration activities have revealed that increased drilling efforts have successfully found and extended existing gold lenses. A key contributor to the uptick in resources is the enhanced gold price calculation, adjusted from $1,750 to $2,000 per ounce.
This higher value allowed for a revised lower cut-off grade leading to more ounces being included in the overall assessment. Rob McEwen, the company’s chairman, noted that these developments will enable robust annual production and extended mine life.
Historic Mining and Future Implications
An intriguing archival report claims that a bulk sample from the Gibson Zone in 1989 produced over 27 grams per tonne of gold, underscoring the historical richness of the area. The geology of the Grey Fox deposit lies close to the reputable Porcupine-Destor fault zone, which has been historically identified as prolific, yielding approximately 110 million ounces of gold.
McEwen Mining's continued geological modeling has identified over 150 mineralized lenses across a mere 1.4 square kilometer area, which is indicative of a strong and potentially sustainable mineralized system.
Resource Categorization and Comparison
A detailed evaluation indicates that all six zones at Grey Fox have shown growth in both indicated and inferred resource categories. Particularly noteworthy is the Gibson Zone, where resource estimates saw a staggering 181% increase, with indicated resources climbing from 139,000 ounces to 290,000 ounces. The inferred resources also saw an 80% increase, reflecting the zone's potential for early production.
Whiskey-Jack Zone Highlights
The Whiskey-Jack (WJ) zone presents itself as a notable area of focus, with an astounding 97% of its mineralization categorized as indicated, alongside an average grade of 5.7 grams per tonne of gold. The proximity of the WJ zone—only 350 meters from the Gibson Ramp—positions it favorably for quick and efficient access to early production opportunities.
