Nuvau Launches Follow up Drilling to Bracemac Footwall Gold Discovery in Matagami
Nuvau Launches Follow up Drilling to
Bracemac Footwall Gold Discovery in
Matagami
Toronto, Ontario--(Newsfile Corp. - August 12, 2025) - Nuvau Minerals Inc. (TSXV: NMC) has begun its
minimum 1,500 m drill program aimed at testing continuity and extensions to the
orogenic gold system
discovered last month
. The discovery was made with the first hole drilled of an inaugural gold-focused
exploration program, in the footwall of the Bracemac-McLeod Mine approximately 200 m below surface.
The follow-up program is being drilled immediately north east of this base metal mine, which was in
production until mid 2022.
The Matagami Property is in the northern Abitibi Region of Quebec, one of the world's most prolific gold
endowed districts. This northern part of the Abitibi region includes Canada's largest gold producing mine
with the country's largest gold mineral reserves: the Detour Lake Mine owned by Agnico Eagle Mines
Limited.
Hecla Mining Company's Casa Berardi Mine, which has produced over 3 million ounces of
gold, is located to the southwest of the Matagami Property (see Figure 1 below).
While the Abitibi's first recorded gold discovery was 119 years ago in Rouyn-Noranda, the Matagami
Property remains one of the largest areas in the region that has not been subject to a gold focused
exploration program. Previous owners were concentrating on defining and developing multiple VMS
deposits into multiple mines that produced extensive copper and zinc for more than 60 years. This was
one of the primary opportunities Nuvau identified when it entered into the agreement to acquire the
Property from Glencore. The Company recently began compiling gold related historic data, as well as
launching several gold-focused initiatives (including till sampling) aimed at defining initial targets for
drilling.

Nuvau's current gold-focused exploration program has identified three initial priority targets:
1
.
Bracemac Footwall Discovery
2
.
Gold-in-Till Anomaly Target
3
.
Thunder Mine (1988) Target
The map below shows the location of these three targets (Figure 2). The vast majority of this 1,300 km

land pack remains open for gold exploration.

1. Bracemac Footwall Discovery
The recent discovery of gold mineralization in the footwall of the Bracemac Mine is located only 25 m
from the access ramp of this permitted mine. The steeply dipping, strong shear zone structure with quartz
veining mineralized with pyrite and locally visible gold was intersected at a depth of approximately 200
m. The visible gold was observed over approximately 0.5 m of core and assays are still pending on the
discovery hole, BRCG-25-001.
Although located within the immediate footwall of the past-producing Bracemac-McLeod mine, the
mineralized structure occurs in a late intrusive that truncated the mine host rock units (see Figure 3). The
intrusive has seen very little drilling as the stratigraphy was not of interest for VMS exploration.
The follow up drill program is now underway to continue to step-out both up and down dip, and along
strike, to test continuity of mineralization within the structural corridor as well as providing critical data on
the dip and strike of the vein.

2. Gold-in-Till Anomaly Target
As part of Nuvau's target generative exploration program, an overburden (till) drilling program was
launched in 2023. This program resulted in the
discovery of significant gold-in-till mineralization that was
announced on March 4, 2025
.
From the 2023 sonic drill program, hole PD-23-030s produced a notable gold grain anomaly detected at
a depth of between 29.26 to 29.87 m in the overburden and featured more than 2,000 gold grains per 10
kg of material. In addition, a near-contiguous sample with 295 gold grains per 10 kg of material between
31.12 to 32.00 m was also encountered with the interval between consisting of a large locally derived
boulder. Based on the almost pristine nature of the gold grains, and their close proximity to the bottom of
the hole, the source is expected to be relatively close to this hole. (See images of gold grains below in
Figure 5.)
To assist in defining targets in this area, a detailed drone MAG survey was completed. The limited rock
outcrops were also mapped recently and together with the MAG data, a drill program is being designed
for later this year. The objective of this drill program will be to gain a better understanding of the local
geological structures and to test for the potential source of the extensive gold grains.

3. Thunder Mine (1988) Target
The Thunder Mine property was acquired by Nuvau in 2023 for its potential for both base metal and gold
mineralization. In 1988, Thunderwood Exploration Ltd. drilled a series of holes as follow-up to a 1959
hole that intersected copper mineralization (see Figure 6).
This follow-up program identified multiple gold-bearing structures; however, no subsequent follow-up
work was completed. Highlight intercepts from the available public domain report include the following:
DT-14-88: 209.00 - 209.80 m (0.80 m) @ 26.40 g/t Au.
DT-10-88: 205.00 - 206.00 m (1.00 m) @ 78.16 g/t Au.
DT-18-88: 100.80 - 107.30 m (6.50 m) @ 1.55 g/t Au, incl.: 0.30 m @ 4.89 g/t Au.
DT-19-88: 226.00 - 231.00 m (5.0 m) @ 2.27 g/t Au, Incl.: 0.50 m @ 10.39 g/t Au.
DT-20-88: 136.80 - 137.10 m (0.30 m) @ 10.37 g/t Au and 204.50 - 205.00 m (0.50 m) @ 6.48 g/t
Au.
DT-21-88: 310.50 - 319.90 m (9.40 m) @ 4.02 g/t Au, incl.: 0.70 m @ 42.03 g/t Au and 0.70 m @
7.30 g/t Au.

About Nuvau Minerals Inc.
Nuvau is a Canadian mining company focused on the Abitibi Region of mine-friendly Québec. Nuvau's
principal asset is the Matagami Property that is host to significant existing processing infrastructure and
multiple mineral deposits and is being acquired from Glencore.
Qualified Person and Quality Assurance
Bastien Fresia P. Geo. (Qc), Technical Services Director of Nuvau and a "qualified person" as is
defined by National Instrument 43-101, has verified the scientific and technical data disclosed in this
news release, and has otherwise reviewed and approved the scientific and technical information in this
news release.
Drill core samples are sawn by staff technicians to create half core splits. One split is retained in the drill
core box for archival purposes with a sample tag affixed at each sample interval and the other split is
placed in a labelled plastic bag along with a corresponding sample number tag and placed in the
shipment queue.
Quality control samples including blind certified reference material ("CRM"), blank material, and core
duplicates are inserted at a frequency of 1 in every 20 samples and sample batches of up to 60 samples
were then shipped directly by Nuvau personnel to the ALS Canada Ltd. preparation laboratory in Rouyn-
Noranda, Québec.
All submitted core samples are crushed in full to 95 % passing less than 2 mm (ALS code CRU-32). A
1000-gram sample was then riffled split from the crushed material and pulverized to 90 % passing 75
μm (SPL-22 and PUL-32a). Pulps are shipped from the preparation laboratory to ALS Canada Ltd.'s
analytical lab in North Vancouver, British Columbia, for assay.
Lead, silver, copper and zinc analyses were determined by ore grade four acid digestion with an
inductively coupled plasma atomic emission spectroscopy ("ICP-AES") or atomic absorption
spectroscopy ("AAS") finish (ALS codes Pb-OG62, Ag-OG62, Cu-OG62 and ZnOG62), whereas gold
was determined by 50 g fire assay analysis with an AAS finish (code Au-AA23).
ALS Canada Ltd. is an accredited, independent commercial analytical firm registered to ISO/IEC
17025:2017 and ISO 9001:2015.
