Omineca Expands Diamond Drilling Program at Wingdam

SASKATOON, Dec. 17, 2024 - Omineca Mining and Metals Ltd. (TSXV: OMM) (OTCQB: OMMSF) ("Omineca" or the "Company"), is pleased to report that the second drill rig (see news release December 5, 2024) has completed its 3^rd hole, a scissor-hole to WD24-38 added to test the down dip extension of veins observed in that hole. The second rig has now commenced its 4^th hole of the program. With the first drill rig on its 4^th hole, 8 diamond drill holes will be completed before the holiday break.

All drill holes to date have encountered wide zones of quartz carbonate sericite alteration with some quartz veins containing various concentrations of localized semi-massive to massive sulphide mineralization (see photos below). Of note, samples from several holes will be metallic screen assayed for coarse gold.

The program has been expanded from 10 to 17 holes and up to 10,000 meters. The first drill hole has been logged, sampled and shipped for assay with logged samples from the second and third holes expected to ship this week. Drilling will recommence in the new year and results will be announced as they are received and analysed.

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.
