Omineca Updates - Readies for Maiden Drill Program and Reopening Placer Recovery

Operations at Wingdam

Saskatoon, SK. July 31, 2020 - Omineca Mining and Metals Ltd. (TSX -V: OMM) (“Omineca”

or the “Company”) reports an update for both its maiden lode gold drilling program at the

Wingdam gold project and the recommencement of the placer gold bulk sampling program in the

Cariboo Mining District, 25 km west of Barkerville, BC.

Field work for the exploration and drilling program was initiated on May 7 th and is ongoing. A

diamond drill is now on site and the commencement of drilling will be announced once plans are

finalized and permits are confirmed.

At the same time, p reparations are being finalized to mobilize remaining equipment to site at

Wingdam and the crew is now waiting for the water level of Lightning Creek to subside in order

to begin dewatering the decline to the underground wor kings of the placer recovery program,

which will also be announced upon commencement.

Lode Gold Exploration Drilling

The central focus of Omineca’s lode gold exploration program is to locate the presumed multiple

bedrock sources of placer gold recovered by Omineca in the 2012 underground bulk sampling

program which yielded 173.5 ounces of gold across the width of the Deep Lead Paleochannel

beneath Lighting Creek . The preliminary results from the current field programs are validating

Omineca’s hypothesis that the sources of the placer gold at Wingdam are likely in very close

proximity upstream to where the gold was recovered.

The current field program is designed to assist in drill targeting for the 2020 drilling program.

Access and drilling permits have been submitted for the first 27 drill holes (~8,000 m) and approval

for this work is anticipated within the coming weeks.

A geological team from Axiom Exploration Group Ltd. (“Axiom”) alongside Omineca’s lead

geologist, Stephen Kocsis, have conducted a series of field sampling programs through May and

June with an initial focus on a region upstream (northeast) and within an approximate 5 kilometer

radius from the first underground crosscut bulk sample location where 173.5 ounces of placer gold

were recovered from the Deep Lead Paleochannel.

The current exploration work area was subject to an earlier SkyTEM survey where a large electro-

magnetic (“EM”) signature was identified immediately upstream of Omineca’s underground paleo

placer gold recovery program at Wingdam. The Lightning Creek river valley represents a major

interpreted structural and erosional feature cross -cutting through several parallel structures

overlying the large SkyTEM EM anomaly. The current area of exploration and d rilling

encompasses the large targets identified by the SkyTEM survey as well as targets identified and

confirmed by Omineca’s 2018/19 airborne UAV magnetic survey program.

Axiom’s May and June sampling programs collected 170 outcrop samples, of which 143 samples

were sent for geochemical analysis. A small soil sampling program was also conducted where 15

samples were sent for geochemical analysis to determine the elemental pathfinders most likely

associated with a confirmed outcrop Au anomaly within the e xploration area. Axiom reports that

based on the results of the 2020 sampling programs to date, the conclusive initial recommendation

is that a comprehensive soil sampling program should be completed ‘upstream’ to the northeast of

the 2012 placer exploration drift and surrounding select outcrop geochemical anomalies.

A team from Axiom is currently conducting the soil sampling program which was recommended

in the logistics report from the first two programs. This program is comprised of a 100 m x 50 m

grid across the primary areas of interest.

Bedrock mapping has identified several significant fault and shear zone structures within the

immediate target area along the productive part of Lightning Creek as well as multiple Paleozoic

intrusive bodies exposed along the eastern half of the work area.

A quartz -rich mylonitic shear zone of note has been identified and sampled by the team of

exploration geologists in the current program. The shear zone was identified in outcrops at the

contact between the Harveys Ridge and Ramos successions forming a z -fold. This zone strikes

across an area about 800 m upstream along Lightning Creek from the Wingdam paleochannel

crosscut. Similar sheared quartz was also mapped and sampled in an isolated exposure about 300

m SE alo ng strike towards the creek. Two other identical zones of quartz-rich shear ing were

recently identified by the crew in isolated bedrock exposures. The second zone, within the Ramos

Succession, is located about 3 40 m across strike or S W of the first zone and the third is located

near the boundary between Harveys Ridge and Keithley successions. The geological team is

extending mapping and sampling to the two new zones.

Stephen Kocsis notes that this structural control pattern is analogous t o some of the gold

mineralized structures found at Barkerville, specifically the contact between the Hardscrabble and

the Downey successions where historic and now contemporary gold deposits have been delineated

by Osisko Gold Royalties and its predecessor s on Island Mountain, Cow Mountain, and

Barkerville Mountain adjacent to Williams Creek. Williams Creek, like Lightning Creek, was a

prolific placer gold producer in the Cariboo Mining District. Mr. Kocsis further notes the

correlation between the elevated Au concentrations found in the Ramos Succession with that found

in the Downey Succession at the Cariboo Gold Project near Barkerville which is typically 30 to

60 ppb Au. Of particular note was that the May sampling program completed by Axiom reported

geochemical assays where 100% of the samples returned reportable Au values, many within the

analogous Barkerville range, including several substantially exceeding the typical values up to 236

ppb Au.

Prior to the May -June program, which is beginning to validate the theory that the source of the

placer gold is proximal to Wingdam and Lightning Creek, inspection of the placer gold recovered

from the 2012 bulk sample suggested multiple lode gold sources upstream of the Wingdam Mine.

Many of the nuggets recovered were jagged and angular, contained quartz inclusions, and a high

silver content which indicates a minimal transportation distance from the bedrock source (<100

meters). Most of the gold particles recovered were coarse -grained flax se ed-like flakes, which

normally travel less than 1 km in a fluvial environment. Less than 5% were fine-grained

(submillimeter), polished gold particles which are normally indicative of travelling further

distances.

To further aid in the exploration and dri lling for the lode sources of the placer gold, Omineca

intends to do further geo-scientific work on the morphology of the placer gold recovered from the

crosscut bulk sample and future extraction to match and identify the surrounding source rocks and

structures. Details will be announced once plans and methodologies are finalized.

Underground Placer Gold Bulk Sample Program

Preparations have been made to dewater and re -enter the decline and begin underground

rehabilitation work to continue bulk sampling the paleochannel where the first test crosscut left

off. Both settling ponds have been rehabilitated and preparations are being finalized to mobilize

pumps and a freeze plant to the Wingdam M ine site. All the required freeze piping remains

installed to the bulk sample face and will only require a pressure test for recommissioning. The

crew is now waiting for the water level of Lightning Creek to subside after an unusually heavy

freshet this year to begin pumping water from the mine workings. With an engineered grout plug

system initiated last year, it is anticipated that dewatering should now be reduced in time to ~3 -4

weeks followed by rehabilitation and underground preparation time of another 4 weeks before

freezing and mining operations are to begin.

The first phase of underground placer recovery is planned to be approximately 125 crosscuts,

similar in size and scope to the 2012 crosscut bulk sample, over the first 300 m of the estimated

2,400 m of the paleochannel that has been subjected to extensive study through 3D seismic, and

historic and contemporary drill holes. Future development plans include geological investigation

and evaluation along the total ~17 km of potential paleochannel (upstream and downstream) within

Omineca’s current claims.

hard-rock tenures along the Lightning Creek valley, where topographic conditions created a thick

overburden which preserved a large portion of the channel from conventional surface placer

mining activity.
