Omineca Set to Re-enter Underground Paleochannel to Excavate Gold Bearing Gravels at Wingdam

SASKATOON, Nov. 7, 2024 - Omineca Mining and Metals Ltd. (TSXV: OMM) (OTCQB: OMMSF) (TSXV: OMM.RT) ("Omineca" or the "Company"), is pleased to announce that the steel tunnel liner plate sections required for D&L Mining ("D&L") to initiate operations have arrived on site and preparations are being made to re-commence mining and gravel extraction at the Company's Wingdam underground paleoplacer project located in the Cariboo Mining District of south central British Columbia.

Tunnelling operations will be restarted in the open crosscut drift where coarse placer gold was recovered in the most recent breakthrough into the paleochannel (see news release of September 6^th, 2024). As previously reported, the dry condition of the paleochannel allows for conventional mining and tunnelling methods using steel tunnel liner in place of the more complex grouted spiling ground support technique. This change to steel tunnel liner provides cost, safety and execution time advantages, as well as additional security to year-round operations regardless of wet or dry conditions at surface.

Omineca will provide further updates as D&L advances into the channel toward the central portion where the highest concentrations of placer gold are known to settle. The current plan is to continue tunnelling and processing gold bearing gravels across the full width of the channel followed by excavation both up and downstream within the central portion of the old riverbed.

About Omineca Mining and Metals Ltd.

Omineca Mining and Metals Ltd.'s flagship Wingdam gold exploration and placer recovery projects are located along the Barkerville Highway 45 km east of the City of Quesnel. The Wingdam Property includes mineral tenures totaling over 61,392 hectares (613 square kms) and in excess of 15 linear kilometers of placer claims, both encompassing the Lightning Creek valley where topographic conditions created thick layers of overburden, which preserved a large portion of a buried paleochannel containing placer gold-bearing gravels. Omineca also has an exploration and diamond drill program currently underway exploring for the potential multiple hard rock sources of the placer gold at Wingdam.
