Omineca Begins Diamond Drilling at Wingdam

SASKATOON, SK – September 22, 2020 – Omineca Mining and Metals Ltd. (TSXV: OMM) (" Omineca"

or the "Company") , announces that it has commenced its maiden diamond drill program at the Wingdam

gold exploration project in the Cariboo Mining District of south-central British Columbia.

Initial drilling is focussed on an area within a one kilometer radius adjacent to and upstream of the single

underground crosscut that yielded 173.4 ounces of placer gold. The drill program follows initial exploration

consisting of airborne geophysics, rock sampling and soil geochemical analysis conducted by Stephen

Kocsis and Axiom Exploration Group’s geological team.

Omineca’s lode gold exploration program targets several NW striking faults where they intersect NE

trending faults identified in the magnetic survey completed in 2018. This structural control pattern is

indicative of Riedel style strike -slip deformation known to produce sub- vertical ore shoots at the Osisko

Gold Royalties’ Cariboo Gold Project located 25 kilometers to the east. The Wingdam and Cariboo Gold

projects share similar lithology and structur e; two of the main ingredients for mineralization in the gold

producing Barkerville Terrane.

Stephen Kocsis, P.Geo, is a qualified person within the context of National Instrument 43- 101 and has

About Omineca Mining and Metals Ltd.

Omineca Mining and Metals Ltd. controls its flagship Wingdam Project and the Fraser Canyon Project

through its wholly owned subsidiary CVG Mining Ltd. The Wingdam Project is located 45 km east

of Quesnel B.C. on the Barkerville highway. The property includes both placer and hard- rock tenures now

totaling over 51,000 hectares ( 510 square kms) surrounding the Lightning Creek valley . T opographic

conditions created a thick overburden which preserved a large portion of an underground channel from

conventional surface placer mining activity. For 2020, Omineca has plans to re- start a bulk sampling

program to recover placer gold trapped underground while also conducting a diamond drill program to

explore for multiple potential hard rock sources of the placer gold.
