Blue Moon, USA
The Company is focused on the advanced stage Blue Moon zinc project. The Blue Moon project is subject to a NI 43-101 Mineral Resource estimate with approximately 7.8 million tons with a grade of 8.07% zinc equivalent for approximately 771 million pounds of zinc, 71 million pounds of copper, 300,000 ounces of gold and 10 million ounces of silver in the Inferred category.. The resource is open at depth and along strike and has favourable metallurgy. A NI 43-101 report detailing the resource is available here and was filed on SEDAR on November 20, 2018. A long section of the 2018 drill program can be found here. The Company plans to advance the project to feasibility and permitting.
The Blue Moon Deposit is located in east central California within Mariposa County in the Foothills. The property is accessible by gravel roads off nearby paved highway. There are active mines in the region and was part of the original California gold rush.
The main transmission lines and a hydroelectric power generation facility are both within one mile of the property. Sea ports, rail and trucking routes are all accessible. It’s a three hour drive to the Oakland port and a 4 hour drive to Reno, Nevada.
Mining by Hecla Mining Company during 1943-1945 produced 55,656 tons grading 12.3% zinc, 0.36% copper, 0.48% lead, 3.75 oz/ton silver and 0.062 oz/ton gold. The property was actively explored and advanced by Imperial Metals, Boliden and Lac Minerals (now Barrick) in the 1980s and 1990s.
Review, verification and analysis of the historical data has provided a NI 43-101 compliant resource estimate of the polymetallic massive sulphide deposit at its Blue Moon project. The technical report was co-authored by Gary Giroux and Lawrence O’Connor. The resource estimate estimated by Gary Giroux at Blue Moon has been classified as inferred.
For resource calculations purposes, it has been assumed that the Blue Moon Deposit would likely be mined by underground methods. The results of the resource estimate are as follows:

Remodelling of the deposit using the digitized data shows the deposit is open both to depth and to the south. The potential to expand the current resources is considered excellent.
Metal Prices and Estimated Recoveries (Metallurgy)
As the Blue Moon is a multi-variable deposit with all variables contributing to the economic value a method of combining the grades into one variable was required. The parameters used were as follows:
Zinc – $1.30/pound – 95% Recovery
Copper – $3.00/pound – 93% Recovery
Lead – $1.00/pound – 95% Recovery
Silver – $17.00/ounce – 65% Recovery
Gold – $1,250.00 /ounce – 70% Recovery
The zinc equivalent equation is as follows:
ZnEq = (Zn%*24.70 + Cu%*55.80 + Pb%*19.00 + Ag(oz/t)*11.05 + Au(oz/t)*875.0)/ 24.70
Recoveries used in the calculation are based on metallurgical testing of drill core undertaken by Lakefield Research (now SGS) on samples of mineralization.
