Delta Extends I-Zone Gold Mineralization by More than 400 Metres, Thunder Bay, Ontario
Delta Resources (DTARF) reports initial channel-sampling results that extend known gold mineralization at the I‑Zone by more than 400 metres eastward at its Delta‑1 Gold Project near Thunder Bay, Ontario.
Rhea-AI Summary
Delta Resources (DTARF) reports initial channel-sampling results that extend known gold mineralization at the I‑Zone by more than 400 metres eastward at its Delta‑1 Gold Project near Thunder Bay, Ontario.
Highlighted results include 4.85 g/t Au over 8.0 m in trench D1‑26‑TR17, and in trench D1‑26‑TR20 intervals of 2.91 g/t Au over 8.3 m and 4.23 g/t Au over 4.3 m. Preliminary outcrop grab samples returned values up to 16.1 g/t Au, with numerous additional channel and grab sample assays still pending due to extended laboratory turnaround times.
The I‑Zone remains open along strike and largely untested at depth. Delta plans a first drilling phase in the I‑Zone sector to test the mineralized system along strike and at depth within the broader Crayfish Creek Fault corridor.
Positive

- Preliminary outcrop grab samples returned up to 16.1 g/t Au
- Historical I-Zone drilling includes 4.32 g/t Au over 41.0 m and other multi-metre, multi-gram intercepts
Negative
- Laboratory turnaround times are several weeks longer than usual, delaying receipt of hundreds of assays
- Channel samples do not represent true widths of host dikes, which are narrower than sampled intervals
- Historical drilling results cited for I-Zone are not NI 43-101 compliant

Toronto, Ontario--(Newsfile Corp. - September 21, 2026) - Delta Resources Limited (TSXV: DLTA) (OTCQB: DTARF) (FSE: 6GO1) ("Delta" or "the Company") is pleased to report initial channel-sampling results that extend known gold mineralization at the I-Zone by more than 400 metres eastward at its Delta-1 Gold Project, approximately 50 kilometres west of Thunder Bay, Ontario. Results include 4.85 g/t Au over 8.0 metres in trench D1-26-TR17 and 2.91 g/t Au over 8.3 metres and 4.23 g/t Au over 4.3 metres in trench D1-26-TR20 (Table 1).
The I-Zone remains open along strike in both directions and is largely untested at depth.
Table 1. Reported Channel Results
| Survey | Azimuth | Length | UTM NAD83 Zone 16 - East | UTM NAD83 Zone 16 - North | Reported Interval |
| D1-26-TR17-01 | 265 | 11.9 | 272182 | 5383001 | 4.85 g/t Au over 8.0 m |
| D1-26-TR20-07 | 74 | 8.3 | 272435 | 5383008 | 2.91 g/t Au over 8.3 m |
| D1-26-TR20-08 | 80 | 4.3 | 272445 | 5383010 | 4.23 g/t Au over 4.3 m |
Preliminary outcrop sampling across the area has also returned gold values such as 2.49 g/t Au, 6.06 g/t Au and 16.1 g/t Au (Figure 1). Laboratory turnaround times are currently several weeks longer than usual due to a notable increase in exploration activity across Canada. Assays remain pending for hundreds of additional channel and grab samples collected as part of Delta's ongoing exploration program.
Additional results will be released as they become available.
Ron Kopas, Chief Executive Officer (CEO) of Delta, commented:
"Our summer exploration program has demonstrated significant eastward continuity over 400 metres that had not previously been established. Our first phase of drilling in the I-Zone Sector will now test the mineralized system along strike and at depth, where we see strong potential for high-grade mineralization.
Our thesis at the Delta-1 Property continues to strengthen as we are only beginning to understand the scale and potential of this system. As we apply a more systematic exploration approach, we believe we will continue to identify highly prospective targets anchored by the Eureka discovery."
Note: Gold mineralization at I-Zone is primarily associated with approximately N—S-trending extensional quartz veins hosted within approximately E-W-trending felsic dikes. Channel samples were oriented to intersect the mineralized veins and, therefore, do not represent the true width of the host dikes. Observed true widths of the felsic dikes at surface are variable and range from less than one metre to approximately four metres. Grab samples are selective by nature and may not be representative of the mineralization on the property.

I-Zone and Crayfish Creek Fault Corridor
The I-Zone is a historically recognized gold occurrence where previous drilling returned several significant gold intercepts, including 4.32 g/t Au over 41.0 metres, 4.53 g/t Au over 14.4 metres, and 4.36 g/t Au over 20.4 metres.
The I-Zone forms part of the broader Crayfish Creek Fault corridor, an underexplored area along a major regional structure where historical exploration by Inco identified more than two dozen high-grade mineral occurrences, many of which have seen little or no systematic follow-up exploration. Delta's current regional program is systematically evaluating these targets using modern exploration methods, with the objective of identifying and advancing additional gold targets for drilling.

Qualified Person
Daniel Boudreau, P.Geo., Vice President of Exploration at Delta Resources Limited, is the Qualified Person as defined by National Instrument 43-101 and has reviewed and approved the technical information contained in this news release.
Quality Assurance / Quality Control
Channel samples were analyzed under Delta Resources' Quality Assurance and Quality Control (QA/QC) program, which includes the systematic insertion of certified reference materials and blanks. Samples containing visible gold, as well as samples returning greater than 2.0 g/t Au on an initial 50 g fire assay, were analyzed using a metallic screening procedure consisting of a 1 kg pulverized sample screened to 106 µm, followed by 50 g fire assay with gravimetric finish. QA/QC results are reviewed by the Qualified Person to ensure analytical results meet acceptable quality-control thresholds.
About Delta Resources Limited
Delta Resources is a Canadian mineral exploration and development company focused on advancing its Delta-1 Gold Project in Ontario. The Company has identified a large, near-surface gold system located approximately 50 kilometres west of Thunder Bay, adjacent to the Trans-Canada Highway. The Delta-1 Property covers approximately 340 square kilometres and hosts multiple gold-bearing corridors, including the Eureka Gold Deposit and the highly prospective I-Zone-Crayfish Creek Fault trend.
The Eureka Gold Deposit extends over 2.5 kilometres in strike length and to depths exceeding 300 metres, with mineralization intersected to approximately 600 metres vertical depth and remaining open in all directions. Highlights include drill intercepts such as 5.92 g/t Au over 31 m (including 14.8 g/t Au over 11.9 m) and 1.79 g/t Au over 128.5 m.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
What follow-up work does Delta plan at the I-Zone after these channel results?
Delta plans a first phase of drilling in the I‑Zone sector. The company said this drilling will test the mineralized system both along strike and at depth, where it sees potential for high-grade mineralization within the broader Crayfish Creek Fault corridor.
How is gold mineralization characterized structurally at the I-Zone?
Gold mineralization at the I‑Zone is primarily associated with approximately north–south-trending extensional quartz veins hosted within approximately east–west-trending felsic dikes. Channel samples were oriented to intersect the mineralized veins, so they do not represent true widths of the felsic dikes, which vary from less than 1 metre to about 4 metres.
What quality assurance and quality control procedures does Delta use for these samples?
Channel samples were analyzed under Delta's QA/QC program, which includes systematic insertion of certified reference materials and blanks. Samples with visible gold and those returning >2.0 g/t Au on an initial 50 g fire assay were reanalyzed using a metallic screening procedure on a 1 kg pulverized sample (screened to 106 µm) followed by a 50 g fire assay with gravimetric finish. QA/QC results are reviewed by the Qualified Person to ensure they meet acceptable thresholds.
Who is the Qualified Person responsible for the technical information in this release?
The Qualified Person, as defined by National Instrument 43‑101, is Daniel Boudreau, P.Geo., Vice President of Exploration at Delta Resources. He has reviewed and approved the technical information in the news release.
What is the broader context of the I-Zone within the Delta-1 Property?
The I‑Zone forms part of the Crayfish Creek Fault corridor, an underexplored area along a major regional structure where historical work by Inco identified more than two dozen high-grade mineral occurrences. Delta is systematically evaluating these targets with modern methods, aiming to identify and advance additional gold targets for drilling within the Delta‑1 Property, which also hosts the Eureka Gold Deposit.
