RPX Gold Expands Gold Mineralization Beyond the PEA Open Pit and
Underground Mine in Support of the Planned PFS
Intersecting 1.87 g/t Gold Over 35.10 Metres
TORONTO--(BUSINESS WIRE)--September 16, 2026--RPX Gold Inc. (“RPX Gold” or the
“Company”) (TSXV: RPX) (OTCQB: RDEXF) is pleased to announce gold (“Au”) assay results
from 25 drill holes totalling 4,336 metres (“m”) from its 2026 ongoing drilling program at the
Wawa Gold Project in Ontario. The Company has now completed approximately two-thirds of
the drilling meterage planned to support the prefeasibility study (“PFS”) and approximately half
of its planned 20,000 m 2026 drill program. The results will be included in an updated mineral
resource that will support a PFS, targeted for completion in H1 2027.
Highlights (See Figure 1, and Tables 1 and 2):
Drilling results extend mineralization at southern end of the Jubilee Deposit beyond
the 2026 PEA mine plan and remains open down plunge:
o 1.87 grams per tonne gold (“g/t Au”) over 35.10 m core length, including 21.50
g/t Au over 1.00 m and 6.22 g/t Au over 2.35 m in SD-26 676
o 1.19 g/t Au over 33.98 m, including 10.00 g/t Au over 0.98 m and 5.77 g/t Au
over 1.07 m in SD-26-674
o 1.68 g/t Au over 16.68 m, including 5.16 g/t Au over 1.19 m and 8.46 g/t Au over
1.16 m in SD-26-677
o 2.66 g/t Au over 9.87 m including 7.02 g/t Au over 2.69 m in SD-26-675
Drilling results add near-surface gold mineralization with potential to increase open
pit resource:
o 2.05 g/t Au over 4.26 m and 4.68 g/t Au over 2.35 m in SD-26-660A
o 1.61 g/t Au over 8.47 m, including 11.50 g/t Au over 0.71 m in SD-26-685
Results build on previously announced drilling post-2026 PEA (see press releases of
December 16, 2025 and May 27, 2026). Combined, these drill results support the
potential to connect the North and South pits in an updated mine plan:
o 8.77 g/t Au over 13.33 m including 30.12 g/t Au over 3.39 m in SD-26-626
o 10.05 g/t Au over 8.59 m including 82.80 g/t Au over 0.92 m in SD-25-616
o 13.82 g/t Au over 4.94 m, including 55.20 g/t gold over 1.04 m in SD-26 639
o 4.63 g/t over 13.25 m, including 18.60 g/t Au over 1.47 m and 14.70 g/t Au over
0.88 m in SD-25-593
o 3.33 g/t Au over 16.78 m including 19.40 g/t Au over 0.97 m in SD-26-627
o 23.20 g/t Au over 1.18 m and 2.09 g/t Au over 5.37 m including 9.67 g/t Au over
0.78 m in SD-26-636
Michael Michaud, President and CEO of RPX Gold, commented “We are pleased with the
progress of our 2026 drill program, with these latest results demonstrating the continuity of
mineralization within and beyond the 2026 PEA mine plan, particularly at the southern end of
the Jubilee Deposit. In addition, the near-surface results reinforce the potential to grow
mineralization with potential to connect the North and South pits in an updated mine plan. With
approximately half of the overall program now completed, we remain focused on expanding and
upgrading the resource as well as continued de-risking of the Wawa Gold Project as we advance
toward an updated mineral resource estimate and PFS in H1 2027.
At the same time, we are focused on advancing other key elements of our development strategy –
toll-milling opportunities, permitting, and Indigenous consultation, including progress on an
IBA. As the PFS-focused drilling nears completion, an increasing portion of the remaining 2026
drill program will shift to exploration targets, testing new areas for potential resource growth
while keeping the Wawa project on track towards production.”
2026 Drilling Program
The previously released 2026 PEA mine plan identified that approximately 63% of open-pit
ounces and 86% of underground ounces included in the economic model were classified as
indicated mineral resources (see news release dated February 18, 2026). To support conversion
of the remaining inferred resources to indicated, the Company announced a 20,000 m drilling
program in preparation for the PFS (see news releases dated May 27, 2026 and July 14, 2026).
The 2026 drilling program aims to:
Complete the conversion of inferred mineral resources to indicated mineral resources in
the mine plan identified in the 2026 PEA;
Acquire additional data for grade validation, and metallurgical and geotechnical purposes
in key areas of the underground mine plan identified in the 2026 PEA; and
Conduct initial follow-up drill testing of several exploration targets identified by previous
drilling in areas outside of the current mineral resource.
Approximately 2/3 of the drilling meterage planned for the PFS has been completed.
Combined with previously announced post-2026 PEA results, the new drilling results continue to
extend gold mineralization in areas of open-pit potential along the Jubilee Shear Zone (Figure 1
and Table 2). This includes the crown pillar of the historic Surluga Mine where targeted infill
drilling in gaps in the 2026 mineral resource continues to indicate the presence of near-surface
gold mineralization, particularly in SD-26-660A and SD-26-662.
Drilling also continues to demonstrate that gold mineralization can be extended beyond the 2026
PEA mine plan in areas that were either sparsely tested or untested in historical drilling
programs. The drilling intersections at the southern edge of the Jubilee Deposit confirmed and
extended gold mineralization in and beyond the 2026 PEA mine plan (Figure 1). Those new
drilling intersections, particularly in SD-26-674, SD-26-676 and SD-26-677, could increase the
inventory of gold mineralization in that area of the Jubilee Deposit that remains open down-
plunge.
Quality Assurance/Quality Control ("QA/QC") Measures
Individual drill core samples are labelled and sawn in half along a pre-marked cutting line. A
consistent half-core sample is then placed in an individual numbered plastic sample bag that is
sealed. The remaining half-core samples are kept at the Company’s core storage facility located
on the Wawa Gold project. Quarter-core duplicates are taken from certain samples to define the
variability of gold distribution. Groups of samples are then placed into durable rice bags sealed
with security seals to be transported by commercial carrier for analysis at Activation
Laboratories Ltd. (Actlabs), Ancaster, Ontario. NQ core assays are obtained by 50-gram fire-
assay with a AA finish or by 1-kilogram metallic screen fire assay. The 1-kilogram metallic
screen assay method is selected for samples anticipated to contain coarse gold and when the
original fire-assay returns results greater or equal to 2.25 g/t Au. The residual coarse reject
portions of the samples remain in storage for a minimum 90-day period if further work or
verification is needed.
As part of its QA/QC program, RPX Gold inserts external gold standards (low- to high-grade)
and blanks every 20 samples and routinely inserts blanks immediately after samples with visible
gold. Quarter core duplicates are routinely inserted to evaluate the natural variability of gold
mineralization. Assay certificates are sent to at least three members of the senior management
team, and they are directly accessible from the WebLIMS portal of Actlabs. Approximately 5%
of the pulps and coarse rejects analyzed at Actlabs are sent to Agat Laboratories in Thunder Bay
for umpire testing.

QUALIFIED PERSON
Jean-François Montreuil, P.Geo., Vice President, Exploration at RPX Gold, and a Qualified
Person as defined under National Instrument 43-101, has reviewed and approved the scientific
and technical information in this press release.
ABOUT RPX GOLD INC.
RPX Gold Inc. is a gold exploration company, advancing the flagship Wawa Gold Project
located in northwestern Ontario, in the Michipicoten Greenstone Belt of Ontario, and is adjacent
to several established gold-producing operations, including those operated by Wesdome Gold
Mines Ltd., Alamos Gold Inc. and Hemlo Mining Corp. The Wawa Gold Project benefits from
strong local infrastructure and excess regional mill capacity.
The Company is evaluating open-pit operations designed to generate early cash flow to help fund
the advancement of the underground operation. This phased approach is aimed at de-risking
development, accelerating the time to revenue and minimizing shareholder dilution. The
approach is subject to the completion of a number of milestones before a production decision can
be made, such as continued drilling and mineral resource definition, conducting additional
metallurgical test work, completing a prefeasibility study, continuing baseline studies as well as
additional permitting and Indigenous consultations, among other factors.
The Wawa Gold Project currently hosts mineral resources from two mineral deposits, namely the
Jubilee Shear and the Minto Mine. The mineral resources include an indicated mineral resource
of 22.909 million (“M”) tonnes grading 1.69 g/t Au containing 1,244,000 ounces Au and an
inferred mineral resource of 9.951 M tonnes grading 1.59 g/t Au containing 509,000 ounces Au,
with both open-pit and underground mining potential. Gold mineralization extends to surface on
a historic mining property, which supports the Company’s phased development strategy. Please
