Omineca Prepares for Accelerated Dewatering at The Wingdam Gold Project, Barkerville, British Columbia

SASKATOON, Oct. 11, 2019 - Omineca Mining and Metals Ltd. (TSXV: OMM) ("Omineca" or the "Company") announces that preparations for the dewatering program are underway at the Wingdam Gold Project. These preparations involve grouting off the connection point between the current project and the deep lead channel from the historic Sanderson Mine which was operational during the 1930's. The resulting reduced water flow should decrease the dewatering time from the expected 3-4 months down to 3-4 weeks. The impact of this on the project economics of the bulk sample is significant, reducing start-up time and overall life-of-project dewatering cost. Once dewatering is complete, underground work to prepare the first zone to be opened for ground freezing and bulk sampling will begin.

Omineca, along with its partners KR Investments Corp. and HCC Mining and Demolition Inc. (collectively "HCC") completed two shallow drill holes from surface into a vent raise that connects the Sanderson Mine to the current underground workings at the Wingdam Gold Project. This connection has allowed water to flow from the historic mine to the current workings accounting for the majority of the water inflow, and represents one of the primary causes of the relatively significant dewatering times associated with the project.

Using the holes drilled from surface into the vent raise, HCC has installed a grout plug at this connection point, which will serve to block off the Sanderson Mine from the Wingdam Gold Project, with the express purpose of either ceasing or significantly limiting water flow from the old mine. Severing the link should restrict water inflows at Wingdam to the natural ground water inflow rate, which is anticipated to be 25% of the current inflow rates. It will take up to two weeks for the grout to properly set-up, at which time testing will commence to ensure that the Sanderson Mine has in fact been sealed off from the Wingdam Gold Project's underground workings. Once this testing is completed, the full dewatering of the underground workings can proceed.

HCC has been actively working on the project since late spring, preparing the site for the commencement of bulk sample activities. This includes the rehabilitation of the settling ponds, which were last used during Omineca's initial bulk sample, completed in 2012.

About Omineca Mining and Metals Ltd.

Omineca Mining and Metals Ltd. controls a 100% interest in the Wingdam Gold Project through its wholly owned subsidiary CVG Mining Ltd. The 2700 ha Wingdam Gold Project is located 45 km east of Quesnel B.C. via the Barkerville highway. The property includes both placer and hard-rock tenures along the Lightning Creek valley, where topographic conditions created a thick overburden which isolated a large portion of the channel from conventional surface placer mining activity.
