DELTA INTERSECTS 1636 G/T AND 697 G/T GOLD OVER 1.0 METRE INTERVALS AND REPORTS VISIBLE GOLD IN TWO STEP-OUT HOLES IN INITIAL PHASE 2 DRILLING AT DELTA-1 IN THUNDER BAY, ONTARIO

Delta Resources Ltd. has provided assay results from the last four drill holes of its 2023 phase 1 drill program along with initial observations on its first drill holes of the 5,000-metre phase 2 drilling at the Delta-1 gold project located 50 kilometres west of Thunder Bay, Ont.

Wide intercepts of gold mineralization were intersected near surface in drill holes D1-23-35 and D1-23-36, extending this style of mineralization an additional 100 metres east of the previously reported drill holes (see release April 25, 2023).

Drill hole D1-23-38 intersected exceptionally high-grade gold mineralization in narrower intervals east of a northeast-trending cross-fault that displaced the mineralized zone toward the south. It is unclear at this point how this high-grade mineralization correlates with the very wide intervals of lower grade west of the cross-structure. Vein widths, density of veining and grade distribution can be highly variable within these large gold systems and hole D1-23-38 is typical of that variability along the favourable structure and geophysical target.

Delta is also pleased to report that the first stepout drill holes from Delta's second phase of drilling announced April 24, 2023, have now been completed. In yet another stepout of 100 metres east of drill hole D1-23-38, drill holes D1-23-40 and D1-23-41 appear to mark a return to the very wide intervals of gold mineralization with visible gold observed in both drill holes. Drill holes D1-23-40 and D1-23-41 are the first drill holes directly testing the Deep Blue target.

Andre Tessier, president and chief executive officer, commented: "These bonanza grades at Delta-1 are very impressive but more important is the fact that we are doing large, 100-metre stepouts and are still consistently hitting strong alteration with higher-grade gold segments hosted within a broader zone of low- to moderate-grade gold. This speaks to the strength of the mineralizing system and the upside potential as our drilling progresses eastward into the larger Deep Blue target area. This deposit is certainly full of pleasant surprises. Given the limited drilling to date, we still have a lot of work ahead of us to better understand this deposit."

Hole D1-23-37 was collared on the same drill pad as drill hole D1-22-09 and intercepted a wide zone of alteration and low-grade gold mineralization in the Alpha and Beta zones with significant grades in the Gamma zone.

The Delta-1 project is located in the Shebandowan greenstone belt and covers a 17-kilometre strike extent of the Shebandowan structural zone.

Analytical protocol and quality assurance/quality control

Chemical analyses reported in this press release were performed at SGS Canada Minerals Laboratories. Sample preparation was performed in Sudbury, Ont. Sampling and analytical procedures are subject to a comprehensive quality assurance and quality control program that includes duplicate samples, blanks and analytical standards.

The following assaying protocol was adopted at Delta-1 in an attempt to reduce the assay variability due to nugget effect caused by visible gold:

• If visible gold is observed in the sample or within the assumed mineralized zone, the assay is performed by metallic screening whereby the entire sample is crushed, a one-kilogram portion is pulverized and screened to 106 micrometres, and analyzed by 50-gram fire assay with gravimetric finish at the SGS Laboratory in Lakefield, Ont. If no visible gold is observed or outside of the mineralized zones, an initial assay is performed by 50-gram fire assay with inductively coupled plasma optical emission spectroscopy finish at the SGS Laboratory in Burnaby, B.C.
• If the assay result exceeds two g/t gold, remaining rejects are pulverized, a one kg portion is screened to 106 micrometres and analyzed by 50-gram fire assay with gravimetric finish at the SGS Laboratory in Lakefield, Ont.

NQ-size drill core was sawed in half lengthwise and half of the core was sampled and sealed in clean plastic bags before being shipped for assay. The remaining half of the core was replaced in core boxes and is stored at Delta's core storage facilities. Standards and blanks are inserted in the sequence of samples on site as quality assurance and quality control in addition to the regular insertion of blank, duplicate and standard samples accredited by SGS Canada Minerals Laboratories during the analytical process.

About Delta Resources Ltd.

Delta Resources is a Canadian mineral exploration company focused on growing shareholder value through the exploration of two very high-potential gold and base metal projects in Canada.

• Delta-1 covers 58.3 square kilometres located 50 kilometres west of Thunder Bay, Ont., where a gold mineralized zone 950 metres long was outlined through drilling in a multikilometre-scale intense alteration halo. Best grades to date include a drill intercept of 14.8 g/t Au over 11.9 metres, within a broader interval of 5.92 g/t Au over 31 m. The zone is open in all directions.
• Delta-2 VMS (volcanogenic massive sulphide) and Delta-2 Gold covers 194 square kilometres in the prolific Chibougamau district of Quebec. The property holds excellent potential for gold-rich polymetallic VMS deposits as well as hydrothermal-gold deposits. Delta targets VMS deposits such as the LeMoine past producer where 760,000 tonnes were mined between 1975 and 1983, grading 9.6 per cent zinc, 4.2 per cent copper, 4.5 grams per tonne gold and 84 g/t silver.
