Toronto, Ontario--(Newsfile Corp. - February 26, 2019) - Crown Mining Corp., (TSXV: CWM) ("Crown" or the "Company") is pleased to announce that it has applied for a permit with the US Forest Service for a drill program on its 100% owned Moonlight Copper deposit. The proposed program will consist of 26 core drill holes totaling 2600 feet to both delineate the oxide cap that sits on top of the large Moonlight copper sulfide deposit and to characterize the oxide zone by sampling for metallurgical testing. Drilling is expected to begin in the summer of 2019 with a total budget of $450,000.

Crown's President & CEO, Stephen Dunn commented: "The Moonlight deposit was evaluated in a report titled "Technical Report and Preliminary Economic Assessment on the Moonlight Deposit" by Tetra Tech dated April 18, 2018 ("PEA") and found on Sedar. The oxide deposit, which had been partially evaluated by previous operators, has not been fully delineated and was treated as waste in the PEA. Proper and positive delineation of the oxide and metallurgical results from this proposed oxide drill program could substantially improve the economics of Moonlight."

About Crown Mining Corp.

Crown controls approximately 12 square miles of patented and unpatented federal mining claims in the Light's Creek Copper District in Plumas County, NE California; essentially, the entire District. The District contains substantial copper (silver) sulfide and copper oxide resources in three deposits - Moonlight, Superior and Engels, as well as several partially tested and untested exploration targets.

The Superior and Engels Mines operated from about 1915-1930 producing over 161 million pounds of copper from over 4 million tons of rock containing 2.2% copper with silver and gold credits.

The Moonlight Deposit was discovered and drilled by Placer Amex during the 1960's. A Preliminary Economic Assessment Study ("PEA"), prepared by Tetra Tech Inc., had the following highlights:

  • After-tax NPV of US$179M at an 8% discount rate and a $3.15 copper price.
  • After tax IRR of 14.6%.
  • Initial Capital Cost: US$513M, including a contingency provision in the amount of US$71M.
  • Plant Processing Rate: 60,000 tons per day (STPD).
  • Average Copper Recovery: 86.0%.
  • Mine Life: 17 years, based on the existing Mineral Resource estimate.
  • Life of mine copper production of 1.5 billion pounds.

Please note the PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Furthermore, there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Readers are encouraged to read the technical report.

Further details of the PEA and the resources on Crown's property and the parameters used to calculate them can be found in the "Technical Report and Preliminary Economic Assessment for the Moonlight Deposit, Moonlight-Superior Copper Project, California, USA" dated April 12, 2018 on both the company's website at or on under the Crown Mining Corp profile.
