Orecap: Kerr Addison Tailings Evaluation Announced, Unlocking Value from Legacy Assets

In This Article:

Highlights:‎

  • Orecap owns ~36 million tonnes of tailings from the historic Kerr-Addison Mine, one of Canada's highest-grade gold producers, with 11 million ounces of past production.

  • The Province of Ontario's updated mining regulations unlock opportunities for sustainable reprocessing of residual metals in tailings.

  • Orecap plans to collaborate with experts to assess metallurgical potential and develop a low-risk processing plan.

  • The initiative aligns with global trends, leveraging proven models to explore economic and environmental benefits of tailings reprocessing.

Toronto, Ontario--(Newsfile Corp. - January 28, 2025) - Orecap Invest Corp. (TSXV: OCI) (OTCQB: ORFDF) (the "Company" or "Orecap") is pleased to unveil its plan to evaluate and reprocess the historic tailings of the Kerr-Addison mine, one of Canada's most storied and highest-grade gold producers. The Kerr-Addison mine, located in Virginiatown, Ontario, has produced a remarkable ~11 million ounces of gold at 9 g/t, earning its place as a key chapter in Canada's mining history. Today, Orecap, within its McGarry property boundary, owns virtually all the mine's tailings, estimated at approximately 36 million tonnes.

Unlocking Untapped Potential
While definitive tonnage and grade data for the tailings is not yet established, historical and modern metallurgical insights suggest the presence of residual gold in the tailings. Metallurgical recoveries from the 1930s through to the 1990's were less efficient than today's standards. This historical inefficiency leaves room for optimism about the economics of the residual gold within the tailings.

Further optimism comes from modern metallurgical data collected by neighboring operations, including studies by Gold Candle Ltd ("Gold Candle"). While Gold Candle does not own the Kerr-Addison tailings, their work on nearby deposits with similar mineralization styles provides valuable benchmarks. According to Gold Candle's metallurgical recovery projections, published in their NI 43-101 report dated August 24, 2023 (Section 13.14), the reported gold recoveries range from 92.5% to 70.2%, depending on the ore type. Orecap emphasizes that these studies do not necessarily reflect historic mining recovery rates. Further, the metallurgical work conducted by Gold Candle was performed on mineralization from the Kerr-Addison Mine, not on the tailings owned by Orecap. While this work provides potential insights, further analysis is required to fully assess the residual grades in the tailings and determine metallurgical recoveries specific to this material.
