Delta Drills 4.18 G/T Au over 17.7 Metres at Eureka and Initiates First Phase of Comprehensive Metallurgical Test Work Program at the DELTA-1 GOLD Project, Thunder BAY, Ontario
DELTA DRILLS 4.18 G/T AU OVER 17.7 METRES AT EUREKA AND INITIATES
FIRST PHASE OF COMPREHENSIVE METALLURGICAL TEST WORK PROGRAM
AT THE DELTA-1 GOLD PROJECT, THUNDER BAY, ONTARIO
February 18, 2026 / Toronto, ON / Newsfile Corp. Delta Resources Limited (“Delta” or “the
Company”) (TSX-V: DLTA) (OTC Pink: DTARF) (FRANKFURT: 6GO1) is pleased to report
assay results from the remaining two holes of its Fall 2025 drilling program and to announce the
initiation of a comprehensive preliminary metallurgical test work program at the Delta-1 Project
in Thunder Bay, Ontario.
Highlights:
• 4.18 g/t Au over 17.7 metres in hole D1-25-145
• 0.91 g/t Au over 16.1 metres in hole D1-25-146
• Initiation of a comprehensive preliminary metallurgical test work program
The drill holes were designed to support early-stage technical evaluation through infill drilling,
while also providing new material for the metallurgical test work program. The holes were
strategically positioned within the core of the Eureka Gold Deposit to serve this dual purpose
(Figure 1). The results confirm the lateral continuity of mineralization between previous drill
holes, an important step in increasing confidence in the mineralization as the Company
continues to de-risk the Eureka Gold Deposit.
Assay results include 4.18 g/t Au over 17.7 metres, 0.74 g/t Au over 11.7 metres, and 0.89 g/t
Au over 13 metres in hole D1-25-145, and 0.91 g/t Au over 16.1 metres and 1.14 g/t Au over 7.3
metres in hole D1-25-146 (Table 1). Both holes were drilled approximately 40 metres from the
nearest previously completed hole. Nearby intercepts from prior Delta drilling include 5.92 g/t Au
over 31 metres (D1-22-018) and 1.79 g/t Au over 128.5 metres (D1-23-060).
Additional material for metallurgical testing was sourced from available coarse assay rejects
from previous drill programs. For the complete table of results from the Fall 2025 drill program,
please refer to Table 2.

Delta has retained the services of Joe Milbourne, FAusIMM, SME Senior Member, to provide
internal technical oversight and guidance for the metallurgical test work program. Mr. Milbourne
has over 50 years of experience in metallurgy, mineral processing, and technical project
evaluation, with extensive involvement in the advancement of exploration and development-
stage mineral projects. He is acting as a technical advisor to the Company and is not
considered an independent Qualified Person for the purposes of National Instrument 43-101.
Ron Kopas, Chief Executive Officer of Delta (interim), commented:
“The initiation of this comprehensive first phase of metallurgical test work represents an
important step in advancing the Delta-1 Project, and particularly the Eureka Gold Deposit
beyond the exploration stage. The results are expected to provide critical insight into the
physical properties, recovery characteristics and processing options, helping to inform future
technical and economic studies while continuing to de-risk the project. We are pleased to be
working with Mr. Milbourne, whose extensive experience will provide enhanced guidance and
technical oversight for the metallurgical test work program.
The infill drilling also helps us to further define the high-quality, higher-grade potential starter pit
area of the Eureka Gold Deposit as we advance the project on multiple fronts, while continuing
to expand the potential of Delta-1 with ongoing property-scale exploration.”

Analytical Protocol and QA/QC
Chemical analyses reported in this news release were performed by AGAT Laboratories, an
independent analytical laboratory accredited to ISO/IEC 17025 by the Standards Council of
Canada (SCC). Sample preparation was completed at AGAT’s facility in Thunder Bay, Ontario.
All sampling and analytical procedures were conducted under a comprehensive Quality
Assurance/Quality Control (QA/QC) program, including the insertion and monitoring of certified
reference materials (standards), blanks, and duplicate samples.
To minimize assay variability associated with the nugget effect from coarse and/or visible gold,
the Company implemented the following assaying protocol at Delta-1:
Where visible gold is observed in the sample or where the sample is derived from an interpreted
mineralized zone, the assay is performed by metallic screening. In this procedure, the entire
sample is crushed, and a 1 kg split is pulverized and screened to 106 µm. Both the coarse and
fine fractions are analyzed by 50 g fire assay with gravimetric finish at AGAT Laboratories in
Thunder Bay, Ontario.
Where visible gold is not observed, or where samples are outside of interpreted mineralized
zones, an initial assay is performed by 50 g fire assay with ICP-OES finish at the AGAT
Laboratory in Thunder Bay, Ontario. If the assay result exceeds 2.0 g/t Au, remaining rejects are
pulverized, a 1 kg portion is screened to 106 µm and analyzed by 50 g fire assay with
gravimetric finish at the AGAT Laboratory in Thunder Bay, Ontario.
NQ-size drill core was sawn lengthwise in half using a diamond blade saw. One half of the core
was sampled, placed in sealed and labelled plastic bags, and shipped to AGAT Laboratories for
preparation and analysis. The remaining half core was returned to core boxes and retained for
reference at Delta’s secure core storage facilities. QA/QC materials including blanks and
certified standards were inserted into the sample stream at the project site. In addition, routine
insertion of accredited blank, duplicate, and certified reference samples was conducted during
the analytical process by AGAT Laboratories, providing further independent QA/QC monitoring.
Mineralized intervals are calculated using a 0.2 g/t Au cut-off grade. Reported intercepts are
constrained to intervals where internal dilution does not exceed 5 m of continuous core grading
below the cut-off.

About Delta Resources Limited
Delta Resources is a Canadian mineral exploration and project development company focused
on its Delta-1 Project in Ontario, where it has discovered a large, near-surface gold deposit
located 50 kilometres west of Thunder Bay, directly adjacent to the Trans-Canada Highway.
The Eureka Gold Deposit extends 2.5 km in strike length, from surface to over 300 metres in
depth. Highlights include drill intercepts such as 5.92 g/t Au over 31 metres (including 14.8 g/t
Au over 11.9 metres), and 1.79 g/t Au over 128.5 metres. Mineralization has been observed up
to 600 metres vertical depth and remains open in all directions. The property covers 297 square
kilometres containing multiple corridors of intense alteration and deformation on strike with, and
to the south of, the Eureka Gold Zone, many of which remain under-explored.
The property also hosts several high-priority targets which expand the gold potential beyond the
Eureka Gold Deposit with exploration continuing to demonstrate strong district-scale upside
across multiple targets.
• Shabaqua Target drilling confirmed higher-grade mineralization in sulphide-rich iron
formation and chert, returning 4.25 g/t Au over 11.8 m, 2.4 g/t Au over 4.3 m, and 1.37
g/t Au over 10.5 m, along with broad bulk-tonnage-style mineralization of 0.16 g/t Au
over 132 m.
• I-Zone Target, located 18 km southwest of the Eureka Gold Deposit, hosts strong
historical (non-NI 43-101-compliant) high-grade intercepts, including 4.32 g/t Au over
41 m, 4.53 g/t Au over 14.4 m, and 4.36 g/t Au over 20.4 m (Landore Resources, 1995–
1997), plus a mini-bulk sample grading 9.9 g/t Au (Mengold Resources, 2008).
• Wedge Area, located 4 km west of the Eureka Gold Deposit, hosts three distinct targets.
Recent drilling expanded the Wedge Zone by nearly 400 m along strike and confirmed
continued mineralization, with gold values of up to 0.73 g/t Au. A new mineralization
style at the Nova Target returned 1.11 g/t Au over 10.3 m, associated with a 500 m
VTEM anomaly. Meanwhile, the Kaspar Target, situated more than 900 m from the
currently defined Wedge Zone, yielded high-grade surface samples of 8.72 g/t Au, 4.01
g/t Au, and 1.75 g/t Au.
