Engineer Gold Mines Begins Camp Rehabilitation at Both

Engineer and TAG

Vancouver, BC, Canada – Engineer Gold Mines Ltd. (the "Company") (TSX -V: EAU | OTC:

EGMLF | WKN: A3EEVJ ) is pleased to announce that crews, supplies and equipment have arrived

on site at its 100% owned Engineer Gold Project , located 30 kilometres southwest of Atlin in

northwestern British Columbia. The crews have arriv ed to re-establish and rehabilitate the two 20-

person camps at its Engineer Mine Project and at the TAG Project in order to expand its 2026

exploration programs (see news release July 28, 2026) . Both camps are already in place and fully

built but have not been used since 2009 (TAG) and 2021 (Engineer).

Spiro Kletas, President and CEO commented, “We are very excited to re -establish the camps at the

Engineer and TAG project sites. The fact that both camps are already in place, built and paid for, is

an enormous advantage for Engineer Gold Mines and our shareholders. This will allow the Company

to have full teams at both sites very shortly and will enable the Company to expedite our exploration

programs.”

About Engineer Gold Mines Ltd.

The Engineer Gold Project encompasses approximately 18,319 hectares in northwestern British

Columbia and is subdivided into three principal target areas: the Engineer Gold Mine, the TAG

Property, and the Wann River prospect.

ENGINEER GOLD MINE

The historic Engineer Gold Mine is a past-producing, underground gold-silver operation. Historical

production between 1910 and 1952 totalled approximately 14,263 tonnes grading 39.4 g/t (1.15

oz/ton) gold and 19.5 g/t (0.57 oz/ton) silver (BC Minfile 104M014).

In 2011, an historical Inferred Mineral Resource as defined under National Instrument 43- 101,

including only the Engineer and Double Decker veins, was completed (Snowden, 2011, amended and

restated in 2018, O’Brien et al - www.sedarplus.ca). The historical resource, based on a 5.0 g/t gold

cut-off, gave an inferred 25,000 ounces of gold at a grade of 19 g/t. The historical mineral resource

was calculated using mining industry standard practices and is deemed to be reliable and relevant

in that it demonstrates the mineral potential of the property. This estimate was based on the following

method and parameters: (1) VLP (long section) approach with projection of mineralized shoots

down-dip and along strike based on surface exposure and/or underground development; (2) The

global grade applied to each vein structure is based on a probabilistic approach, with grades

assigned to domains from historical production figures; (3) All grades were diluted to minimum

stoping width of 1 m; and (4) A density factor of 2.8 t/m3 was used which is believed to be

conservative.

A thorough review of all historic data performed by an independent QP, along with additional

exploration work, including diamond drilling, is required to confirm results and to produce a current

mineral resource estimate.

TAG PROPERTY

The TAG Property is located approximately 6 kilometres north of the historic Engineer Mine and is

associated with a 6km long structurally controlled mineralized system related to splays off of the

Llewellyn Fault. The majority of the diamond drilling to date has concentrated on the southern 2 km

section of the structure. Significant historical diamond drill intervals from TAG include: Hole

TAG06-23 which assayed 1.7 g/t Au and 5.1 g/t Ag over 26.7 m (including 3.52 g/t Au over 4.7 m);

hole TAG07-29 which assayed 1.3 g/t Au and 5.9 g/t Ag over 35.0 m; TAG08-51 which assayed 1.8

g/t Au and 7.4 g/ t Ag over 24.3 m; and TAG08- 59 which assayed 1.5 g/t Au and 8.05 g/t Ag over

42.1 m (Fekete and Simper (2009), Fekete and Skinner (2007); ARIS reports #30931 and #29581).

WANN RIVER PROSPECT

The Wann River prospect is located 4 kilometres south of the Engineer Mine and represents a highly

prospective, underexplored target. Exploration work to date has identified a mineralized corridor

approximately 800 metres by 180 metres in extent. While mineralization at the Engineer Mine and

TAG Property is charact eristic of epithermal-style systems, the Wann River prospect represents an

orogenic gold target associated with the prolific Llewellyn Fault and has returned significant gold

and silver values, including a quartz grab sample of 263 g/t gold and 1,350 g/t s ilver from the Lum

showing (Aspinall (2011); ARIS Report #32004).

Historic diamond drilling of 17 holes in 2011 returned numerous gold and silver intercepts. The

most significant intervals were from hole WR030211 which assayed 11.3 g/t Au and 76.2 g/t Ag

over 1 m, and hole WR040111 assaying 11.3 g/t Au and 94.8 g/t Ag over 1.0 m (Aspinall, 2011;

BC ARIS Report #32478). In addition to prior drilling, Wann River has undergone several surface

sampling programs which returned good gold-silver and base metal values.
