Omineca Commences the Underground Portion of Rehabilitation for its Placer Gold Bulk Sample Program at Wingdam

SASKATOON, SK, April 29, 2021 /CNW/ - Omineca Mining and Metals Ltd. (TSXV: OMM) ("Omineca" or the "Company") reports that it has commenced the underground portion of rehabilitation at the Wingdam placer gold bulk sampling project, 40 kilometers east of Quesnel in the Cariboo Mining District of British Columbia. Omineca's joint venture partner has been on site for the past several months dewatering, setting up and equipping for the resumption of underground placer gold recovery operations including camp, power, ventilation, heat and mine rescue and now continues work underground.

The dewatering of the decline and mine workings with the temporary grout plug system installed in 2020 has significantly reduced pumping time and water volumes.  The water level is currently holding approximately 2/3 of the way down the decline. Once rehabilitation reaches the temporary grout plug level, it will be replaced with an engineered permanent plug prior to moving on to the mine face.

The 2021 bulk sampling program is designed to continue the successful placer gold test sample program initiated in 2012. That program utilized ground freeze technology to recover 173.4 ounces of placer gold from a single 2.4-metre by 2.4-metre by 23.4-metre-long drift across the gold-bearing paleochannel located approximately 50 metres beneath Lightning Creek. This initial phase of the bulk sample program, slated for 2021, includes the first 300 metres of 17,000 metres of potential paleochannel on Omineca's claims.

About Omineca Mining and Metals Ltd.
Omineca Mining and Metals Ltd.'s flagship Wingdam gold exploration and placer recovery project is located along the Barkerville Highway 45 km east of the town of Quesnel. The property includes hard-rock tenures totaling over 50,000 hectares (500 square kms) and in excess of 17 linear kilometers of placer claims, both encompassing the Lightning Creek valley where topographic conditions created a thick overburden which preserved a large portion of an underground channel with placer gold-bearing gravels. Omineca also has a diamond drill program currently underway exploring for the potential multiple hard rock sources of the placer gold at Wingdam.
