Omineca Intersects 3.2m of 0.438% Copper at

Mouse Mountain

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

("

Omineca

" or the "Company"), is pleased to announce the results from its recent 2,000 metre drill

campaign at the Mouse Mountain project located approximately 15 kilometers due west of

Omineca's Wingdam gold project in the Cariboo Mining District of south-central BC. Highlights

include drillhole MM21-04, which intercepted 12 metres of 0.156% copper followed by 28 metres of

0.104% copper and a separate 3.2 metre interval in monzonite assaying 0.428% copper. The 2,000

metre drilling program intersected extensive sulphide mineralization in volcanic breccias interspersed

with intrusive monzonite and monzonite breccias on the south west and south sides of Mouse

Mountain, this is approximately 1km south of the mineralization at the Valentine zone and 2km south

of the Rainbow zone mineralization. Planning for a follow up drill program based on these results will

be announced when finalized.

Omineca has earned a 50% interest in the Mouse Mountain property and with report filing will have

formed a Joint Venture with CanAlaska Uranium Ltd. (TSX-V: CVV; OTCQB: CVVUF; Frankfurt:

DH7N) for the further exploration of the property.

CanAlaska President,

Peter Dasler

, comments, "The property lies within a major trend of Tier 1

porphyry copper and copper-gold deposits and is located close to established infrastructure. The

current drill program has allowed a better interpretation of the stratigraphy at Mouse Mountain, and

the continuity of the mineralized monzonite and monzonite breccias. We are looking forward to

working with Omineca to advance to new discovery using this information."

Previous drilling conducted by various companies focused on surface showings and related resistivity

targets and did not fully test the surrounding geophysical chargeability anomalies. The last drill hole

(RVC08-19) completed by Richfield (the previous property operator), intersected a non-magnetic

monzonite breccia assaying 0.36% copper between 398 to 418 meters depth. This hole is located

immediately adjacent to the northern end of the large chargeability anomaly on the west flank of

Mouse Mountain and 800 metres north of the current drill targeting.

The project is centered on Mouse Mountain, 12km east of

Quesnel, BC

. The geology hosts a

hydrothermal system with copper-gold mineralization spread over a large area associated with

typical copper porphyry style alteration. Additional smaller copper showings extend further out from

this system indicating potential for a large-scale porphyry copper and gold system. The current drill

program was aimed at sulphide targets interpreted by geophysics, south of the previous drill

targeting. The mineralization intercepted in the drilling confirmed the targeting and extended the

mineralized monzonite footprint

.

About Mouse Mountain

Mouse Mountain is located within the prolific Quesnel Terrane, a major regional mineral belt that

hosts alkaline and calc-alkaline porphyry copper-gold-molybdenum deposits. The

Quesnel

terrane

extends for 2,000 km northward from the

Canada

-US border and hosts among the province's largest

copper mining operations including the

Gibraltar

, Mount Milligan, and Copper Mountain mines.

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 property includes

hard-rock 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 a thick overburden which preserved a large portion of an underground channel

with 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.
