Mining Operations Initiated at Wingdam

Paleoplacer Project

SASKATOON, SK

,

Dec. 22, 2021

/CNW/ - Omineca Mining and Metals Ltd.'s (TSXV: OMM)

("Omineca" or the "Company") announces that the Company's joint venture partner and mining

contractor, Lightning Creek Mining ("LCM") has begun it's hydraulic grouting operations for

Omineca's Wingdam underground Paleoplacer project located in the Cariboo Mining District,

British

Columbia

. Grout holes above the crosscut working space are currently being drilled to be followed

by a grout curtain hydraulically pumped into place, a setting up period and testing after which the

first mining operations will begin. Updates will be provided as the inaugural grout crosscut program

progresses.

Ken Hamilton

, President of LCM comments, "Work, setup and preparation has gone extremely well,

and the BC government has been very cooperative and expeditious in assessing our plans, tests,

and data especially as it pertains to safety, water management and environmental stewardship.

Their support is also evidenced with the recent grant of a 2-year extension to Omineca's existing

permit. We look forward to getting mining operations for this unique project underway".

Further to the August update, to date LCM has:

Lab tested in situ materials (water pressures, bedrock, paleochannel material)

Dewatered decline and mine workings, depressurized the paleochannel and associated

catchment areas

Installed, inspected, and reported a grout plug to permanently disconnect the extensive

underground workings of the Sanderson Mine from the Wingdam underground operations.

Completed, submitted design specifications, and plans for hydraulic grout mining operations.

Completed, submitted the ground water management plan.

Completed underground electrical system installation

Completed vent raise enhancement, including new ventilation system, secondary egress, and

water discharge system

Installed water management systems including

drain holes below the workings complete with valves and pump hookup

water monitoring holes drilled above, below and at mine face

pumps, valves, and meters installed

Procured all equipment required for installation of grout curtain

Procured all project specific equipment required for mechanical mining underground including an

Antraquip 50 roadheader

Drilled pilot and grout holes (ongoing)

Prepared for drifting: surveying, pilot hole drilling and cutter/roadheader preparation

Designed and commissioned gravity separation facility (trommel and wash plant)

Placer Gold Extraction

The mining method will involve a series of crosscuts and drifts running the length of the underground

paleochannel starting downstream from the first crosscut bulk sample completed in 2012. Stage 1

will take the series of crosscuts and drifts downstream for the first 300 meters. The Company has

mapped through sampling, historic drilling, and 3D seismic, 2.4 kilometers of potentially placer gold

bearing paleochannel both upstream and downstream of the successful 2012 crosscut. Omineca has

an additional 14 kilometers of claims along the Lightning Creek valley which will be explored for the

potential continuation of the gold-bearing paleochannel through drilling and 3D seismic programs.

The 2012 bulk sample was extracted from a

2.4m

x

2.4m

x

23m

crosscut and yielded 173.4 troy

ounces (5.4 kilograms) of placer gold using freeze mining technology to stabilize the ground.

In the same way as the operations from 2012, the placer gold will be recovered by gravity

separation methods. The material excavated from the bedrock sill of the paleochannel (gravel, sand,

and silt) will be processed using water with a trommel and wash plant located underground.

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 Wingdam Property

includes mineral tenures totaling over 50,000 hectares (500 square kms) and in excess of 15 linear

kilometers of placer claims, both encompassing the Lightning Creek valley where topographic

conditions created thick layers of overburden, which preserved a large portion of a buried

paleochannel containing 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.
