About Minnova Corp.

Minnova Corp. is a near term gold producer focused on the restart and expansion of its 100%-owned PL Gold Mine in the prolific Flin Flon Greenstone Belt of Central Manitoba. The project is situated on a past-producing mine site and benefits from significant existing infrastructure, including a 1,000 tpd processing plant and valid underground mining permit (Environment Act License 1207E).

A positive 2018 Feasibility Study, based on an underground development plan and a gold price of US$1,250 per ounce, outlined a robust 5-year mine life with an annual production rate of 46,493 ounces. Considering current high gold price Minnova is revising the mine development plan to prioritize lower-cost open pit mining methods for the initial years of production before transitioning to underground methods. The new mine plan leverages the full 1,000 tpd mill capacity and targets reduced operating costs compared to the previous underground-only model. A revised mine development plan is underway and will be the subject of a Preliminary Economic Assessment and Feasibility Study to be completed in 2026.

The current global gold resource remains open to expansion, as does the reserve. The Mineral Resource Estimate will be revised in 2026, using current consensus gold price assumption and will incorporate all drilling conducted after the 2018 Feasibility Study, including the upcoming 15,000-meter drill program scheduled for 2025 and 2026.
