Omineca Announces Operational Re-Start of

the Underground Placer Gold Recovery

Program at Wingdam

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

(OTCQB: OMMSF) ("Omineca" or the "Company"), is pleased to announce the re-start of

underground operations at the Wingdam placer gold project. D&L Mining, working with ground

stabilization specialists BAT Construction Ltd., are currently setting up and preparing the

underground workings in advance of re-entering the paleochannel containing gold bearing gravels

beginning at the already established crosscut heading #3.

Following delays related to the provision of geotechnical submissions to the BC Ministry (EMLI),

operations are now set to begin under the mine plan utilizing tunnel liner plate and/or grouted fore-

poling (spilings) as needed for ground support in advancing into the gold bearing gravels. The

entrance heading will be at a location described in previous news releases, where mining conditions

exhibited very dry gravel at the breakthrough from bedrock into the gold bearing paleo-gravels.

Under the mine plan, miners will use either grouted fore-poling followed by the application of

shotcrete after excavation or tunnel liner plate where applicable. There are advantages to both

types of artificial ground support depending on the characteristics and conditions encountered. D&L

has restarted operations with preparatory tasks including rehabilitating the haulage/access drift,

cleanout and upgrading dewatering sumps, ventilation upgrades, bulkhead installation and

evaluation/reinforcement of existing bulkheads as necessary. With all equipment, mining supplies,

and manpower now aggregated on site and operations well underway it is expected that gold

bearing gravel recovery will commence in the very near term.

Omineca will provide further updates as D&L advances into the channel toward the central portion

where the highest concentrations of placer gold are known to accumulate. The current plan is to

continue tunnelling and processing gold-bearing gravels across the full width of the channel followed

by excavation both up and downstream within the central portion of the old riverbed.

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

.
