Exploration Programs

DELTA COMMENCES 10,000-METRE DRILL PROGRAM AT EUREKA AND I-ZONE,

DELTA-1, THUNDER BAY, ONTARIO

September 22, 2026 / Toronto, ON / Newsfile Corp. Delta Resources Limited (“Delta” or “the

Company”) (TSX-V: DLTA) (OTCQB: DTARF) (FRANKFURT: 6GO1) is pleased to announce

the commencement of a 10,000-metre drill program at its 340-square-kilometre Delta-1 Gold

Project, located approximately 50 kilometres west of Thunder Bay, Ontario. The program will

test extensions of gold mineralization at the Eureka Gold Deposit and continuity along the I-

Zone mineralized trend.

1) Eureka: drilling will test the depth and down-plunge potential of the mineralized system,

as well as its lateral extensions, towards the Shabaqua target, where hole D1-25-150

returned an interval of 4.25 g/t over 11.8 metres, approximately 2 kilometres west of

Eureka (see January 13, 2026 press release).

2) The I-Zone: drilling will test the continuity of gold mineralization at depth and along strike

of the recently extended mineralized trend (see September 21, 2026 press release).

Additional drill targets may be defined as results from the summer 2026 surface

exploration program are received and interpreted.

Ron Kopas, Chief Executive Officer (CEO) of Delta, commented:

“This drill program is designed to test some of the most significant opportunities we currently

see for expanding the mineralized footprint of the Eureka Gold Deposit. We are stepping out

aggressively to test the interpreted westward plunge of the higher-grade core at depth as well

as exploring the westward continuity of the deposit towards the Shabaqua area.

At the I-Zone, our objective for this first phase of drilling is to establish continuity both vertically

and along strike of the recently defined eastward continuity of the mineralization over 400

metres. As results continue to come in from the ongoing surface exploration program at the I-

Zone Sector, additional drill targets may be refined and tested. Surface exploration work will

continue in parallel with the drilling program as long as weather conditions permit.”

About Delta Resources Limited

Delta Resources is a Canadian mineral exploration and development company focused on

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 km 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.
