Extending Gold Mineralization 50 Metres from
High-Grade Thundermine Intercept
New assays continue to demonstrate continuity of the
mineralized system
Toronto, Ontario--(Newsfile Corp. - September 17, 2026) -
Nuvau Minerals Inc. (TSXV: NMC)
is
pleased to report additional assay results from its 2026 summer drilling program at Thundermine (also
called Thunderwood) in Matagami, Québec. Hole TH-26-11, located approximately 50 metres shallower
than TH-26-08, intersected 17.37 g/t gold (Au) over 2.40 metres within a broad mineralized interval. The
new intersection provides an additional pierce point between TH-26-08 and historical drilling, further
supporting continuity of the mineralized system.
Highlights of drill results:
17.37 g/t Au over 2.40 metres in TH-26-11, within a broader 165-metre interval averaging
0.37 g/t Au characterized by variable densities of mineralized veins.
TH-26-11 is located approximately 50 metres shallower than TH-26-08, which intersected
138.9 g/t Au over 4.4 metres, and halfway toward historical drilling, adding another
mineralized pierce point to the system.
Every Nuvau summer drillhole assayed to date has returned gold mineralization, with six
additional holes pending and the system remaining open.
"TH-26-11 is a 50-metre step-out from TH-26-08 and demonstrates continuity of the system," said
Christina McCarthy, Nuvau's Chief Executive Officer. "The hole returned 17.37 g/t Au over 2.40 metres
within a 165-metre mineralized interval, in the same altered tonalitic host and quartz-tourmaline vein
array intersected throughout the program. Remember, this Thundermine property has not been
systematically tested for over 40 years, and orogenic systems of this style in the Abitibi are known for
their significant vertical persistence. Thundermine remains open along the interpreted trend to the
southeast, as shown in our previously announced diagrams
1
, and at depth, with assays from six holes
still pending."

Mineralization Continues at Thundermine
TH-26-11 intersected the same altered tonalitic intrusive and quartz-tourmaline vein system observed
throughout Nuvau's drilling at Thundermine. Gold grades and vein density vary considerably through the
intrusive, with discrete higher-grade veins occurring within broader zones of lower-grade veinlet and
associated disseminated mineralization. These results remain consistent with Nuvau's interpretation of a
Val d'Or-analogue orogenic gold system developed within a fractured intrusive host. The Thundermine
system remains open along the interpreted trend and at depth.

11 relative to recent and historical drilling. See previous press release

Note: In all figures and tables, reported intervals are core lengths; true widths are unknown. Composite grades are length-
weighted, with unsampled intervals and assays below detection assigned 0 g/t Au. Mineralization also occurs outside the
reported composite intervals.
Quality Assurance, Quality Control, and Data Verification
Drill core is logged, photographed, sawn in half, and sampled at Nuvau Minerals' secure core facility.
One half of the core is submitted for analysis, and the remaining half is retained on site for reference.
Samples are sealed in individually labelled plastic bags and transported under chain-of-custody
procedures to MSALABS in Val-d'Or, Québec, an independent ISO/IEC 17025-accredited laboratory.
Samples are dried, crushed to achieve approximately 70% passing 2 mm, and prepared for analysis.
Gold assays are completed using PhotonAssay™ technology on a nominal 500 g aliquot. The
Company's quality assurance and quality control (QA/QC) program includes certified reference
materials, blanks and duplicate samples, representing approximately 11% of all submitted samples.
Additional QA/QC samples are inserted at intervals that contain visible mineralization. MSALABS also
applies its internal quality control procedures in accordance with its accredited analytical protocols.
Analytical results are reviewed through a comprehensive QA/QC verification process, including the
evaluation of standards, blanks, and duplicate samples. Reanalysis is conducted systematically where
QA/QC criteria are not met. The Qualified Person reviews the analytical results, QA/QC data, and
verification procedures disclosed herein and considers the results to be reliable and suitable for
reporting.
