Corporate Updates

Omineca Completes Pump Down Test at Wingdam

Saskatoon, SK. November 21, 2019 – Omineca Mining and Metals Ltd. (TSX -V: OMM)

(“Omineca” or the “Company”) reports completion of a pump-down test on its flagship Wingdam

project, designed to determine the success of the grout ing program announced on October 11,

2019. This test, along with diminished recharge rates of water inflow since the test, indicate that

the Company has severed the link between the current and historic underground workings at

Wingdam. The test further indicates that the project should benefit from an 85% decrease in dewatering

time. Additionally, all necessary work on the settling ponds has been completed.

Omineca, along with its partners, are currently planning the full dewatering program at Wingdam,

along with rehabilitation of underground workings from the 2012 bulk sample program. During

the rehabilitation phase, the Company will also install an additional engineered grout plug to

permanently seal the project area from the historic workings upstream.

Omineca and its partners anticipate having the Wingdam Project dewatered before the end of 2019.

About Omineca Mining and Metals Ltd.

Omineca Mining and Metals Ltd. controls a 100% interest in both the flagship Wingdam Project

and the Fraser Canyon Project, through its wholly owned subsidiary CVG Mining Ltd. The 2700

ha Wingdam Project is located 45 km east of Quesnel B.C. on 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 preserved a large portion of the channel

from conventional surface placer mining activity.
