Winshear Portsoy Project - Successful Metallurgical Testwork Produces Marketable Copper and Highly Attractive Nickel Concentrates
Winshear confirms flotation viability at its Portsoy project, validating metallurgical results despite ongoing cash burn.
Winshear Metals Corp. has released initial metallurgical testwork results for the Rodburn Target at its Portsoy Project in NE Scotland. The company states that composite samples from 2023/2024 drill holes demonstrate amenability to conventional sequential flotation.
Testing was conducted by Blue Coast Research Ltd, supervised by company metallurgists and approved by Qualified Persons. Head assays average 0.82% Copper, 1.64% Nickel (1.38% in sulphide form), and 0.11% Cobalt. Expected recoveries are 75-80% for Copper and 60-65% for Nickel, with further locked-cycle studies anticipated to improve yields.
Nickel concentrate grades are projected at 14-16% with >1% Cobalt and 0.54% payable Copper. Copper concentrate grades are projected at ~25% with <1% Nickel, falling below typical penalty charge thresholds.
The release marks a logical progression in the Portsoy Project’s exploration and earn-in timeline. Historical news establishes a clear sequence: an option agreement in August 2025, TSX-V approval in December 2025, a $2.5 million financing in March 2026, Phase 1 drilling in May 2026, geophysical targeting in July 2026, and metallurgical validation in July 2026.
The results confirm technical viability and processing amenability, slightly de-risking the project by proving that conventional methods can produce marketable concentrates. However, the news does not introduce new discovery dimensions, resource estimates, or financing. It represents a standard technical milestone that aligns with prior management guidance and the earn-in commitment.
The market impact is expected to be incremental.
Winshear Gold Corp. is a Canadian exploration company focused on identifying and acquiring mineral properties. Its flagship asset is the Portsoy Nickel-Copper-Cobalt Project in Aberdeenshire, Scotland, where the company holds an earn-in agreement to acquire a 100% interest from Peak Nickel Ltd. The company also holds a secondary project, the Thunder Bay Gold Project in Northwestern Ontario, which is also under an earn-in structure.
The company is currently in the exploration stage. No known mineral resources or reserves have been defined, and the company is entirely dependent on exploration success and external financing.
