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

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

British Columbia

Saskatoon, SK. October 11, 2019 – Omineca Mining and Metals Ltd. (TSXV: OMM)

(“Omineca” or the “Company”) an nounces that preparations for th e dewatering program are

underway at the Wingdam Gold Project. These preparations involve grouting off the connection

point between the current proje ct and the deep lead channel fro m the historic Sanderson Mine

which was operational during the 1930’s. The resulting reduced water flow should decrease the

dewatering time from the expect ed 3-4 months down to 3-4 weeks. The impact of this on the

project economics of the bulk samp le is significant, reducing s tart-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 M ining 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 W ingdam 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 h as installed a grout plug at this

connection point, which will serve to block off the Sanderson M ine from the Wingdam Gold

Project, with the express purpose of either ceasing or signific antly 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 reha bilitation 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 topographi c conditions created a thick

overburden which isolated a large portion of the channel from conventional surface placer mining

activity.
