Delta Identifies three Significant Gold Anomalies from the 2024-25 I-Zone Sector Till Survey and Reports Drill Results from the latest Regional Exploration Drill Program

February 27, 2026 / Toronto, ON / Newsfile Corp.  Delta Resources Limited (“Delta” or “the Company”) (TSX-V: DLTA) (OTC Pink: DTARF) (FRANKFURT: 6GO1) is pleased to report the preliminary interpretation from the 2024-25 till survey conducted by IOS Géosciences in the I-Zone sector, located approximately 18 kilometres southwest of the Eureka Gold Deposit and about 60 kilometres west of Thunder Bay, Ontario. The till survey, completed in the fall of 2025 (see September 17, 2025 news release), has identified at least three significant gold anomalies and one nickel anomaly, further reinforcing the potential for expansion and new discoveries in the area. Delta is also pleased to report assay results from its most recent regional exploration drill program at the Delta-1 Gold Project. Highlights Include: A sample containing 629 total gold grains (normalized to 10 kg fraction) and an anomalous fine-fraction value of 86.8 ppb Au collected west of the I-Zone, which may reflect an extension of the known I-Zone showing or indicate a previously undiscovered gold occurrence. A sample containing 488 normalized gold grains collected from an area with no known historical gold occurrences, approximately 3 km northeast of I-Zone, hosted within a distinct geological package. A sample containing 152 normalized gold grains, likely derived from the New Road Zone, a known gold occurrence identified by Delta as a high-priority, yet-to-be-drilled exploration target. A large anomalous nickel trend pointing to an area northeast of the I-Zone prospect. Ron Kopas, Chief Executive Officer of Delta, commented: “With the 2024–25 till data and its interpretation now completed, Delta continues to demonstrate district-scale discovery potential beyond the Eureka Gold Deposit. This is most evident in the I-Zone sector, where historic work indicates high-grade gold mineralization in a style distinct from Eureka. In the coming months, we will advance an aggressive follow-up exploration program in the I-Zone area while continuing to accelerate development of the Eureka deposit and nearby priority targets”. 2024-2025 Till Survey In the fall of 2024, Delta initiated a large-scale regional till survey in the western portion of the Delta-1 property, which hosts the I-Zone and associated gold showings. The survey was originally scheduled to resume in the spring of 2025 but was ultimately completed later in the fall. Results from recent till sampling and geochemical interpretation within the I-Zone sector have identified multiple highly anomalous gold and nickel responses, supporting the presence of both known and previously unrecognized mineralized sources in the area. Note: Gold grain counts are reported as normalized values to 10 kilograms of processed till material to allow consistent comparison between samples of varying weights. A highly anomalous till sample collected near the I-Zone returned 629 normalized gold grains, along with an anomalous fine-fraction gold value of 86.8 ppb Au. Based on ice-flow indicators and Quaternary interpretation, this anomaly is considered unlikely to have been sourced directly from the existing I-Zone trench. The sample may represent either an extension of the known I-Zone gold showing or a previously undiscovered gold occurrence proximal to the I-Zone. A second anomalous sample returned 488 normalized gold grains and was collected from an area with no known historical gold occurrences. This sample is hosted within a distinct geological package separate from the I-Zone, suggesting the presence of an additional, previously unrecognized gold-bearing system within the broader project area. A third anomalous sample returned 152 normalized gold grains and is interpreted to be derived from the New Road Zone, a known gold occurrence previously identified by Delta Resources as a high-priority exploration target that has not yet been drill tested. In addition to the gold anomalies, compilation of geochemical data has identified a large anomalous nickel trend extending to the northeast of the I-Zone prospect, highlighting an additional exploration vector and supporting the multi-commodity potential of the area. Collectively, these results reinforce the prospectivity of the I-Zone sector and support continued follow-up exploration and target refinement aimed at advancing near-term drill targets. The combined 2024-2025 surveys in the I-Zone sector consisted of 209 sample sites and covered an area of approximately 70 km². The I-Zone sector is located 18 kilometres southwest of the Eureka Gold Deposit and hosts several high-grade gold showings, including historical (non-NI 43-101 compliant) drill intercepts of 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 (Landore Resources, 1995–1997), as well as a 1,000-kg mini-bulk sample (Mengold Resources, 2008) that returned an average grade of 9.9 g/t Au. Figure 1: Map of 2024-2025 Normalized gold grain counts (till, 10 kg) Drill Results The 1,386-metre follow-up drill program, consisting of six (6) holes, was designed to further evaluate the gold-bearing system identified by the Company’s previously reported intercept of 1.11 g/t Au over 10.3 metres at the Nova Target (see February 4, 2026 news release), to test the extent of associated geophysical anomalies, and to further assess the Wedge Zone and Kaspar Target areas (Figure 2). Multiple samples returned anomalous gold mineralization including: values up to 0.62 g/t Au in D1-26-154 and D1-26-157, further extending Wedge Zone mineralization to the east; values up to 0.5 g/t Au within an 8 m-wide sulphide-bearing iron formation in D1-26-158; anomalous samples in D1-26-156, located 220 m east and along the predicted strike of the Nova Target and anomalous samples from initial drill-testing of the historic Kaspar Zone. Anomalous gold within favorable host rocks confirms a large, active hydrothermal system at Wedge and informs future drill targeting (Table 1). “This phase of drilling demonstrated the presence of anomalous gold within favorable host rocks confirming our geological model and providing critical data to refine targets and improve future drill effectiveness. Encouraging indicators of scale and continuity support clear pathways for continued value creation as exploration advances,” commented Dan Boudreau, VP Exploration of Delta.

Analytical Laboratory and QA/QC Procedures All till samples were collected by IOS Géosciences. Samples were collected from subsurface till using a combination of hydraulic excavator and hand-shovel methods, depending on overburden conditions. Excavation was employed where necessary to access till beneath historical glacial lake sediments. All samples were logged in the field, collected following procedures consistent with previous surveys on the property, and spatially referenced using UTM NAD83 coordinates. Field operations were supervised by IOS Géosciences to ensure sample integrity and procedural consistency. Fine-fraction (
