Omineca Provides Update on Placer Gold

Recovery Operations at Wingdam

SASKATOON, SK

,

Sept. 29, 2022

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

("Omineca" or the "Company") and their Joint Venture partner Hamilton Gold Royalties ("HGR") are

pleased to announce that the lead underground mining contractor for its Wingdam Paleoplacer joint

venture, Lightning Creek Mining Corp ("LCM") has engaged Fortis Mining Engineering and

Manufacturing ("Fortis"), to provide additional mining services. LCM & Fortis report that mining

activities and the processing plant are fully operational and that, in cooperation with provincial mines

regulators, LCM has updated the mine plan and plant for optimal, continuous go-forward operations.

Fortis has now advanced several meters into the paleochannel while continuing to grout and drain

the bedrock interface. Currently, at the interface and above the pay gravels, Fortis is reinforcing the

area at the paleochannel's bedrock contact with grout, steel sets and cement to remediate expected

ground water inflows. Following the fortification of this section while carefully monitoring water and

material, Fortis will advance into the pay zone, feed the pay gravel to the wash plant, and continue

across the channel. Extensive advance drilling indicates drier material through the channel until the

crosscut reaches the opposite rim.

The wash plant, an in-house, custom-made trommel, sluice and boil box system, has now been

reconfigured, optimized, and is operating well. Interestingly, during test runs of the plant using

presumed non gold-bearing material (bedrock cuttings and material from layers above the pay

gravels) flake and fine placer gold was recovered.

Mr.

Ken Hamilton

, president of Lightning Creek Mining, "We are very pleased to bring Fortis in as

our lead underground mining contractor. Their scale, innovation and experience are ideally suited to

execute this unusual but high reward task. We are highly confident that we will achieve a sustainably

accelerated mining and processing pace from here on as the base crosscut is established. I look

forward to having them continue here at Wingdam and with related projects going forward."

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

City of Quesnel

. The Wingdam Property

includes mineral tenures totaling over 61,392 hectares (613 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 an exploration and diamond

drill program currently underway exploring for the potential multiple hard rock sources of the placer

gold at Wingdam.
