OMG NEWS RELEASE 1 Omai Gold Commences Exploration on East Wenot Extension and Broccoli Hill Target

Exploration Programs

OMG NEWS RELEASE 1

Omai Gold Commences Exploration on East

Wenot Extension and Broccoli Hill Target

October 29, 2021 Toronto, Ontario — Omai Gold Mines Corp. (TSXV: OMG) ("Omai" or

the "Company") is pleased to report that exploratio n has commenced on the East

Wenot Extension and on the Broccoli Hill target, at the Omai property in Guyana.

The current drilling program that focused on the We not deposit beneath the past

producing pit, was completed yesterday. The program consisted of 16 holes totalling

9,367 metres, with final assay results pending. P&E Mining Consultants are engaged

as the independent Qualified Person and have commen ced the Wenot resource

study. This allows the technical team to initiate a broader exploration program on the

Omai property to include drilling the extension of the Wenot deposit to the east, plus

the Broccoli Hill target, both located near the past-producing pits.

East Wenot Extension

The Wenot Shear Corridor is part of a wide east-wes t trending gold-mineralized

geological structure with 3 kilometres of drill-ind icated strike length across the

property. The Wenot pit, covering roughly 1.7 km of the strike length of this structure,

produced 1.4 million ounces of gold 1 to a depth of 190 metres. Like the classic regional

shear structures that host many of central Canada’s significant gold mines, several

episodes of crustal deformation were focused along this shear structure creating

permeable fracturing to significant depths, that allowed hydrothermal fluids to invade

and deposit gold within the open fractures and breaks.

Drilling is scheduled to start in mid-November, to explore the eastern extension of the

Wenot shear. Work will commence from the eastern e nd of the pit (~306000E) and

continue along an initial 800 metres, following the trend of the shear. This area has

seen no commercial mining, however abundant pitting in the surficial alluvial

material attests to gold that has attracted small s cale miners. Significant gold

mineralization has been identified in this area by several shallow holes drilled along

this trend from 1993-95 but testing to depths of only 50 to 75 metres into fresh rock.

Sedar.com, including March 31, 2006 AIF and news release August 3, 2006.

OMG NEWS RELEASE 2

Gold was intersected on ten 50-metre spaced section lines, with the best intersections

(west to east) including 21m @ 1.3 g/t Au (306130E) , 27 m @ 3.6 g/t Au (in saprolite), 9

m @ 2.6 g/t Au (306380E) and 15m @ 1.9 g/t Au(30653 0E) (see figure 1 and figure 2).

Since the holes were short, they did not fully test the width of the shear corridor in this

area, nor the depth extent of the gold mineralizati on. The drilling, scheduled to

commence in mid-November, will focused on expanding the known mineralization

and evaluating the potential for a near-surface economic deposit in this area.

Broccoli Hill

Broccoli Hill (“BH”) is a conspicuous hill that sit s less than 300 metres east of the

Fennell pit and 300 metres north of the Wenot pit. Combined, these two pits

produced over 3.7 million ounces of gold 1. BH has been an attraction for artisanal

miners for over 100 years and has seen minor surficial exploration for several decades.

Previous auger and soil surveys have identified num erous gold anomalies on BH,

including one auger hole that sampled 12.4 g/t Au f rom a 4 to 6 meters depth in

saprolite adjacent to a large area of pork knocker (artisanal miner) activity (Figure 3).

The abundance of past placer gold workings in the lowlands flanking the hill, together

with the numerous scattered artisanal workings on t he hill itself suggests a gold

source somewhere on BH. It is a very compelling target, interestingly, with little to no

drilling.

Figure 3. Broccoli Hill – Soil and auger sampling & Artisanal mining

Airborne geophysics completed in 2020 shows a magne tic-low signature over BH, a

characteristic of the adjacent Fennell deposit. At Fennell, gold occurs within a series

of relatively flat lying structures within a quartz diorite plug known as the “Omai

Stock”, with a diameter at surface of roughly 400 m etres. At Zijin’s Aurora Mine,

located approximately 200 km northwest of Omai, the ir Rory’s Knoll gold deposit

which is often compared to the Omai stock, has a fo otprint only 200-metres in

diameter. Broccoli Hill, covering an area of about 500 m by 700 m, with the underlying

bedrock still of unknown affinities, certainly has the potential to host such a deposit.

Figure 4. Aeromagnetic data (red = magnetic highs; blue = magnetic lows)

Field work at Broccoli Hill commenced in late Septe mber with trenching and

mapping to investigate the underlying geology, in order to better identify drill targets.

The tropical environment of Guyana creates a pervas ive thick saprolite weathering

and often an overlying ferruginous laterite that effectively conceal and mask bedrock

geology.

The excavator on site was sent to Broccoli Hill to open up trenches and some of the

old roads, and to develop a trail along the ridge crest. The work was done to improve

access and to expose saprolite for mapping and samp ling. The trenching was

successful at exposing saprolite and a significant area was found to have an

abundance of quartz crystals or grains in the ferricrete. It is possible that these quartz

grains, which appear to be floating in the ferruginous matrix of hematite, goethite and

jarosite, and in some exposures could represent a r esidual texture of a quartz-rich

intrusive underlying portions of Broccoli Hill. It is also possible that a Fennell-type

intrusive may not come to surface and would require deeper drilling. Two to three

drill holes, planned for late this year, will target some of the best gold anomalies in the

soil and auger sampling, areas of pork knocker workings and areas possibly underlain

by granitic intrusives. These initial drill holes will provide valuable information on the

bedrock underlying BH to direct further drilling.

Fennell Target

Fennell is one of primary targets on the Omai property, based on results of a 46-drill

hole exploration program completed by Iamgold in 20 07. This drilling identified a

significant gold deposit beneath the past producing pit.

The Fennell pit produced 2.4 million ounces between 1993 and 2004 1. It was mined to

a depth of 250m where it bottomed at a barren diabase sill. After production ceased,

Iamgold completed the exploration beneath the sill and completed a resource report.

Impressive results included 43 intersections of over 1 oz/ton over one metre, as well as

a few samples with over 1000 oz/ton Au over one met re. This drilling reached a

maximum depth of about 960 metres with the deepest holes ending in

mineralization, suggesting even further depth potential.

Omai has started modelling this historic data and plans to initiate a drill program on

the Fennell target in Q2 of next year. This work will require deeper holes to verify the

historic resource (to be NI 43-101 compliant) and t o explore the depth extent of this

mineralization.

Elaine Ellingham, CEO commented “Completing the dri lling to support the Wenot

resource study is quite an achievement for the new Omai team. With this

accomplished, we are very excited to step out to explore some of the other prime near-

mine targets. Areas such as Broccoli Hill and East Wenot have excellent potential for

both significant new discoveries and for expanding known zones of mineralization.

Wenot East is one of those areas where limited hist oric drilling identified very

interesting gold mineralization, but was not pursued. These offer great opportunities

for us to test the extent of these zones and assess their economic potential. We expect

to begin drilling the East Wenot Extension and to complete a couple of initial holes at

Broccoli Hill before the holiday break in December.”

Sample collection, assaying and data management

Standards, blanks and duplicates are entered at regular intervals. Samples are sealed

in plastic bags and shipped to the ActLabs certified laboratory in Georgetown, Guyana,

respecting the best chain of custody practices. At the laboratory, samples are dried,

crushed up to 80% passing 2 mm, riffle split (250 g), and pulverized to 95% passing 105

μm, including cleaner sand. 30 g of pulverized material are then fire assayed by atomic

absorption (AA). Initial assays with results above 3,000 ppb gold are re-assayed with

gravimetric finish. Standards and blanks meet with QA/QC specifications.
