VANCOUVER, BC, Nov. 11, 2024 /CNW/ - GoldMining Inc. (the
"Company" or "GoldMining") (TSX: GOLD) (NYSE American:
GLDG) is pleased to report additional assay results from the 2024
auger drilling program at its 100% owned São Jorge Project ("São
Jorge" or the "Project") in the Tapajós gold district ("Tapajós"), Pará
State, Brazil.
Highlights:
• The auger drilling program successfully identified several new
gold-in-bedrock targets, directly underlying large high-tenor
surface soil anomalies at São Jorge.
• Peak assays exceeded expectations for this style of drilling,
returning several +1 gram per tonne gold ("g/t Au") intercepts in
shallow weathered bedrock, including highlight intercepts:
• 1 metre ("m") at 10.2 g/t Au from 14 m depth;
• 5 m at 2.78 g/t Au from 10 m depth; and
• 3 m at 1.05 g/t Au from 12 m depth.
• At least three of the high-tenor contiguous gold-in-bedrock
targets warrant additional follow-up drilling at the William South
zone, part of an emerging multi-kilometre trend defined by soil
and auger drill anomalies located approximately 2 km north of
the São Jorge deposit. All targets remain open with potential for
further expansion along strike.
• Only 13% of the broad gold-in-soil anomalies across the Project
have been tested to date with top of bedrock auger drilling. The
Company currently plans to continue with systematic auger
drilling in 2025 with the objective of delineating additional gold-in-
bedrock targets and to conduct follow-up deeper drilling with the
objective to potentially discover additional gold resources at São
Jorge.
Tim Smith, Vice President of Exploration of GoldMining,
commented: "To complement the previously reported encouraging
gold intercepts from the 2024 São Jorge step-out core drilling
program, the auger drilling program has yielded several new zones of
shallow gold-in-bedrock mineralization. Mounting evidence appears to
point to additional corridors of gold mineralization at the Project, which
were initially identified by systematic grid pattern gold-in-soil sampling
and which now have been confirmed through auger drilling to have a
proximal bedrock source. The high-grade gold values intersected by
auger drilling have exceeded our expectations and underpin the
exploration potential and quality of the broader São Jorge mineral
system. Several high priority targets have been identified for follow-up
deeper drilling with the objective to further expand gold mineralization
at the Project."

São Jorge Drill Program Overview
The Company commenced a systematic program of auger and
diamond core drilling at São Jorge in May 2024 (see news release
dated May 29, 2024). The objectives of the program included
confirmatory drilling within and near the margins of the existing São
Jorge gold deposit (the "Deposit"), as well as exploratory drilling of
identified gold targets in areas with no previous drilling, located within
1-2 km of known mineralization.
The auger drilling program focused in an area located approximately 2
km north of the São Jorge deposit to follow up on the large, multi-
kilometre high tenor 'William South' gold-in-soil anomaly. All assays
have now been received and the results demonstrate very
encouraging indications of primary gold mineralization in bedrock,
which highlights that the large, regional-scale São Jorge property has
the potential to host additional corridors of mineralization. Follow-up
RC and/or diamond core drilling is required to test for deeper bedrock
mineralization with the objective to potentially discover and define
additional zones of gold mineralization at São Jorge.
São Jorge comprises an extensive land area of some 45,997 hectares
that lies within the active and rapidly developing Tapajós gold district
(see Figure 1), which is estimated to have produced over 20 million
ounces of gold historically from artisanal mining of surface deposits,
according to the Brazil National Mining Agency. The Tapajós is home
to Serabi Gold Plc.'s producing high-grade underground Palito Mine
and G Mining Ventures Corp.'s ("G Mining") Tocantinzinho Gold Mine,
which recently declared commercial production (see G Mining news
release September 3, 2024).
São Jorge has the advantage of being located near paved Hwy BR-
163 and a new 138 kV powerline corridor, which ties into the district
electrical grid recently constructed for the Tocantinzinho Gold Mine.
Exploration activities at São Jorge are operated from a permanent
camp near the existing deposit which is just 3 km from the highway.

Auger Drilling Program
The 2024 power auger drilling program comprised 3,098 meters for
approximately 206 holes, which was completed in September 2024.
The program primarily targeted the high priority 'William South' area
located approximately 2 km north of the São Jorge deposit. William
South comprises a broad high-tenor zone of anomalous gold-in-soil
(see Figures 2 and 3), measuring approximately 2 km x 2 km with soil
assays peaking at 2,163 ppb Au (2.163 g/t Au).
The auger drilling utilized a powered 20 centimetre diameter rotary
drill head capable of penetrating to 15-20 m depth, with vertical drill
holes completed on an approximately 25-50 m x 50 m grid pattern. A
geologist or technician supervised the drilling to log the drill cuttings
and distinguish transported overburden from in situ weathered
bedrock. Sampling is conducted on 1 m intervals with assaying to 5
parts per billion ("ppb") Au detection. The drill method is open-hole,
therefore contamination and/or dilution of precious metal grades by
material from higher in the hole is possible. The advantages of the
auger program include the low detection limit assay results, coupled
with the interpretation of the geological profile to provide a quick,
inexpensive and effective direct mapping for the presence of gold
mineralization in the uppermost portion of the residual weathered
bedrock profile. This information can be used to guide follow-up
exploration drilling using larger equipment such as RC or diamond
core drilling. The auger drilling assay results are illustrated in Figure 2
and Figure 3, and details are provided in Tables 1 & 2.
Background gold values in both residual weathered bedrock and
overlying transported soils is expected to range from nil to 1-2 ppb Au,
thus values of greater than 10-25 ppb Au are considered to be
'elevated', and values greater than 100 ppb Au interpreted to be
'highly anomalous'. The auger program at William South has to date
returned several +1 g/t Au intercepts, including a best intercept of
17.14 g/t Au over 1 m from 12 meters depth (SJTRD-082-24).
Analysis of the auger program assay results indicates that
approximately 17% of all holes returned highly anomalous assay
results (greater than 100 ppb Au), confirming the presence of gold
mineralization in weathered bedrock in several areas. Furthermore,
the grid drilling program has identified several areas with clusters of
anomalous results interpreted to indicate semi-contiguous zones of
mineralization over 100's metres and remaining open along strike.
Indications of multiple contiguous high tenor primary gold
mineralization occurrences in bedrock is compelling for the potential
discovery of new gold resources at William South and warrants
deeper follow-up drilling which is planned for 2025. Positive
confirmation of underlying mineralization in close proximity to surficial
gold-in-soil anomalies is further encouraging for more widespread
application of auger drilling – a cheap and rapid sub-surface
geochemical test – across other gold-in-soil anomalies located
throughout the Project. Several additional target areas are planned for
systematic auger drill testing in 2025.
