Bunker Hill Secures Ball Mill Capable Of Increasing Annual Production Throughput Capacity To 2,100 tpd

Back to all news


  • Enables production throughput of 1,800 tons per day (tpd) as envisaged in the Prefeasibility Study
  • Potential capacity of up to 2,100 tpd, subject to future detailed engineering and mine planning
  • Purchase price of $675,000, of which $100,000 non-refundable payment made; remaining instalments in Q4 2022
  • Located within 500 miles of the Bunker Hill Mine, previously utilized at a western US mining operation
  • Planned delivery to Bunker Hill Mine in Q1 2023, consistent with scheduled mill construction activities

TORONTO, Canada, September 20, 2022 – Bunker Hill Mining Corp. (CSE: BNKR) (“Bunker Hill” or the “Company”) is pleased to report that it has secured a ball mill capable of increasing production throughput at the Bunker Hill Mine.

Sam Ash, CEO of Bunker Hill, stated: “We are excited to secure a ball mill capable of delivering the 1,800 ton per day mine plan envisaged in our Prefeasibility Study.  Subject to future detailed engineering and mine planning, the mill could also support a throughput increase to as much as 2,100 tons per day.  Given the potentially very long life of the Bunker Hill Mine, this optionality represents an obvious source of value creation.  We look forward to finalizing the purchase and integrating it into our mill construction plans.”

The equipment secured includes a ball mill, motor and numerous spare parts, and is being purchased from D’Angelo International LLC.  The mill being purchased is 13.5’ diameter by 20’ in length, is powered by a 2,000 horsepower motor, and is intended to fulfill the 1,800 tpd mine plan in the PFS.  A grindability study has indicated a maximum throughput capacity of 2,100 tpd under Bunker’s ore specifications; through continued mine planning and optimization, the Company plans to investigate the feasibility of this run rate in future mine models.  The mill was previously utilized at a mining operation in the western US, within 500 miles of the Bunker Hill Mine.  The Company is planning delivery for Q1 2023, consistent with scheduled mill construction activities. 

A non-refundable down payment of $100,000 has been paid, with two payments to follow in October and December of 2022 for a total purchase price of $675,000.

Wilson, CPG, President of Resource Development Associates Inc. and a consultant to the Company, is an independent qualified person as defined by NI 43-101 and is acting as the qualified person for the Company.
