Omai Gold Mines Corp. (TSXV:OMG) (“Omai” or the “Company”) is
pleased to announce exploration results from initial trenching and
drilling on the Broccoli Hill target, at its Omai project in
Guyana. Trenching exposed a quartz-rich shear zone with samples
assaying 29.3 g/t Au, 7.8 g/t Au, 5.0 g/t Au and 2.2 g/t Au along a
40-metre strike. A first round of drilling on Broccoli Hill,
totalling 690 metres, intersected gold mineralization with four of
the six holes returning assays greater than 1 g/t Au and as high as
4.04 g/t Au over 0.9 m and 0.91 g/t over 6.8 m.
Elaine Ellingham, Chief Executive Officer,
commented, “We are pleased to have delivered on our goal of
completing an NI 43-101 mineral resource estimate on Wenot by the
end of 2021 (see news release Jan 4, 2022). This new mineral
resource is quite an achievement for our first year. We are also
pleased to report that our initial trenching and drilling on
Broccoli Hill, that commenced late in 2021, has already resulted in
several significant gold values.”
“Broccoli Hill is an area located only 300
metres north of the Wenot pit and less than 200 metres east of the
Fennell pit. These two pits combined, produced over 3.7 million
ounces of gold1. After field work and trenching in October and
November, we completed six initial wide-spaced holes on Broccoli
Hill before the holiday break in December. We intersected gold in
four of the six holes and consider this very successful for first
pass drilling on a large, relatively untouched target area. With
the knowledge gained, this week we started additional trenching,
mapping and sampling. Over the next couple months, we will advance
some of the property’s prime exploration targets, including
Broccoli Hill, that hold potential for new near surface
mineralization amenable to open pit mining,” stated Ms.
Ellingham.
Broccoli Hill has been worked by artisanal
miners for over 100 years. Broad gold anomalies were identified by
previous auger and soil surveys and the airborne geophysical
signatures are similar to those of the Fennell deposit. The
abundance of past placer gold workings in the lowlands flanking the
hill, together with the numerous scattered artisanal workings on
the hill itself, indicate a nearby gold source (Map 1). Exploration
across this large 900m by 700m area has been hampered by a lack of
knowledge of the underlying bedrock lithologies due to deep
tropical weathering of the bedrock to clay-weathered saprolite to
depths of 25 to 60m, complicated by transported
laterite.
Trenching with an excavator on the northwestern
part of Broccoli Hill in November exposed a quartz-veinlet-rich
zone. Samples assayed 29 g/t Au, 5.0 g/t Au, 2.2 g/t Au, and 7.8
g/t Au along a 40 m strike. The orientation of these
northeast-trending, northwest dipping veinlets is consistent with
some of the higher-grade zones within the Fennell deposit, located
less than 300 metres to the west. A 1990’s era shallow auger hole
approximately 80 metres east of this trench assayed 12.4 g/t Au
from a sample taken from a 4 to 6 m depth.
1 Past production at the Omai Mine (1993-2005)
is summarized in several Cambior Inc. documents available on
SEDAR.com, including March 31, 2006 AIF and news release August 3,
2006.
Six initial diamond drill holes totalling 690
metres were completed on Broccoli Hill in December, ranging in
depth from 74 to 200 metres. Two of these holes (21ODD-027 and
-032) were located to test the high grade, quartz-rich zone
identified in the northwest trench and the other four holes were to
test a combination of soil geochemical anomalies, interpreted
structures from the geophysics and other possible quartz veining
and felsic dikes identified from our trenching and mapping. These
holes, spanning 850 metres across Broccoli Hill, provide
considerable encouragement with four of the six holes returning
assays of more than 1 g/t Au, three with values of greater than 2
g/t Au, and higher values of 4.04 g/t Au, and 2.96 g/t Au in holes
28 and 30, respectively. The gold is associated with intervals of
quartz and quartz-ankerite veining and weak veinlet stockworks, and
in hole 28 appears hosted in a deeply weathered felsic dike. The
assay results for the Broccoli Hill drilling are presented in Table
1 below, and Table 2 summarizing drill hole locations and Maps 1
and 2 are presented at the end of this news release.

Drill holes 21ODD-027 and -032 tested the
northwest area of Broccoli Hill near the high-grade trench and
auger samples. Hole 21ODD-027 was collared in 25 m of laterite and
saprolite, then cut several narrow intervals of sparse
quartz-ankerite veining developed in weakly metamorphosed,
propylitic-altered andesite and basalt. Assays include 1.3 g/t gold
over 1.5 m from 72.0 to 73.5 m. Hole 21ODD-032, collared 60 metres
east of hole 027, had better results with 0.91 g/t gold across 6.8
m, 2.40 g/t gold across 1.5 m and visible gold was identified at
145m, but with no significant assay results. This drilling provides
evidence that the favourable northeast trending gold-bearing vein
system seen in the Fennell deposit continues east into Broccoli
Hill and to depths of at least 100 metres.
Holes 21ODD-028, -029 and -031 were drilled in
the central area of Broccoli Hill. Hole 028, near the hilltop,
tested a large >0.1 g/t gold-in-soil anomaly where trenching
exposed a quartz-bearing ferruginous duricrust (with anomalous gold
at 70 to 180 ppb) which is interpreted to be the weathering surface
developed over a felsic intrusive. The hole cut a set of
saprolitized quartz-bearing felsic dikes high in the hole, with one
assaying 4.04 g/t gold over 0.9 metres. Most of the hole
intersected andesitic to basaltic lithologies with a few narrow
quartz veins with only anomalous gold. Holes 029 and 031 were also
located to test the broad soil anomaly. Hole 031 intersected an
overprinting of silicification and patchy biotite alteration,
indicative of higher temperatures and possibly of a nearby
intrusive, but with no significant gold values.
Hole 21ODD-030, located over 840 metres east of
hole 027, tested a strong soil-auger anomaly (with values >0.2
g/t gold). A sample from 18.0 to 19.5 metres returned 2.40 g/t gold
over 1.5 m in a weathered basalt within the saprolite and
additional quartz veining continued into fresh rock but without
significant gold values. A scattering of quartz vein fragments
observed while establishing the drill pad are likely related to
this mineralization. Within this hole, sheared granodiorite lenses
were observed and below 75 m a visually impressive wispy
calc-silicate alteration stockwork is developed in basalt,
containing garnet-diopside-rhodonite altered xenoliths. No gold
values were returned but late stage rhodochrosite veining noted
near the bottom of the hole marks the contact between basalt and
microdiorite.
This late 2021 trenching and drilling provides
valuable information on Broccoli Hill, confirming the presence of
gold mineralization across the large target area. Mineralization is
consistent with the previously mined deposits, being associated
with stockworks of quartz veinlets or brittle fractured and
annealed felsic dikes. With this information, additional field work
including trenching and mapping recommenced this week. Drilling is
expected to re-start in 3 to 4 weeks.
Quality Control
Omai maintains an internal QA/QC program to
ensure sampling and analysis of all exploration work is conducted
in accordance with best practices. Certified reference materials,
blanks and duplicates are entered at regular intervals. Samples are
sealed in plastic bags and shipped to MSALABS Guyana Inc., a
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. Certified reference materials
and blanks meet with QA/QC specifications.
