19.41 Million Ounces Of Measured And Indicated Gold Equivalent Ounces
Tudor Gold Corp. (TSXV: TUD) has filed a Technical Report, which includes the Initial Mineral Resource Estimate for the Goldstorm and Copper Belle Zones at the Treaty Creek Project.
The project is located within the heart of the Golden Triangle of north-western British Columbia, Canada and on trend from Seabridge’s KSM Project situated five kilometres southwest.
The Report is titled “Technical Report and Initial Mineral Resource Estimate of the Treaty Creek Gold Property, Skeena Mining Division, British Columbia, Canada”, dated April 23, 2021, with an Effective Date of March 1, 2021.
Highlights of the March 2021 Mineral Resource Estimate:
- 19.41 million ounces of Measured and Indicated gold equivalent ounces (AuEq) at an average grade of 0.74 gpt AuEq is estimated for the Goldstorm-Copper Belle deposits.
- 14.15 million ounces of Measured and Indicated AuEq ounces at an average grade of 0.72 gpt AuEq is within a constraining open-pit shell and 5.26 million Measured and Indicated AuEq ounces at an average grade of 0.80 gpt AuEq is for the out-of-pit Mineral Resources.
Cut-off grades of 0.30 gpt AuEq were used inside the constraining open-pit shell Mineral Resource Estimate and a higher cut-off grade of 0.46 gpt AuEq was used for the out-of-pit Mineral Resource Estimate which includes underground constrained blocks.
The Goldstorm Zone remains open to the northeast, to the southeast and down dip at depth to the northwest.
A total of 218 drill holes, totalling 105,658.8 metres, were reviewed for the Mineral Resource Estimate completed by P&E. Many of these holes are outside the Goldstorm-Copper Belle deposits and were not used in the Mineral Resource Estimate.The Goldstorm-Copper Belle area has 132 holes.
In addition to the 17.33 million ounces of gold in Measured and Indicated Mineral Resources and 7.22 million ounces of gold in Inferred Mineral Resources, there are 93.41 million ounces of silver estimated as Measured and Indicated Mineral Resources, with an additional 40.57 million ounces of silver in Inferred Mineral Resources.
The Measured and Indicated Mineral Resources are also estimated to contain 1.096 billion pounds of copper, with an additional 330 million pounds of copper in Inferred Mineral Resources.
A bulk density of 2.80 t/m3` was based on measurements of samples collected by P&E during their field visits.
5m x 5m x 5m three-dimensional block modelling was used for the Mineral Resource Estimate.
Measured Mineral Resources are defined by four or more drill holes within 100 metres; Indicated Mineral Resources are defined by four or more drill holes within 200 metres.
Metal prices used were US$1,625/oz Au, US$19/oz Ag, US$2.80/lb Cu with process recoveries of 88% Au, 30% Ag and 80% Cu. A C$16.50/tonne process and C$2 G&A cost were used.
The constraining pit optimisation parameters were C$2.50/t mineralized and waste material mining cost and 50-degree pit slopes with a 0.30 gpt AuEq cut-off.
The out-of-pit parameters were at a C$10/t large scale bulk mining cost. The out-of-pit Mineral Resource grade blocks were quantified above the 0.46 gpt AuEq cut-off, below the constraining pit shell and within the constraining mineralised wireframes. Out–of-Pit Mineral Resources exhibit continuity and reasonable potential for extraction by a bulk underground mining method.
