ENGINEER GOLD MINES EXPLORATION PROGRAM UNDERWAY

The 2026 phase I exploration program is under way on Engineer Gold Mines Ltd.'s 100-per-cent-owned Engineer gold project, located 30 kilometres southwest of Atlin in northwestern British Columbia (see news release dated April 29, 2026). This large property comprises 18,319 hectares covering a 25-kilometre-long contiguous claim block and hosts the historic Engineer gold mine, the TAG property, the Wann River prospect, plus numerous additional mineral occurrences.

The first phase of the 2026 program consists of soil and rock sampling at Engineer, soil geochemistry, and an in depth core review and resampling at TAG. The company is fully permitted to follow this with a phase II program consisting of diamond drilling, excavator trenching and induced polarization geophysical surveys in the Engineer mine area. Phase II plans will be announced once finalized.

The Engineer project hosts multiple styles of mineralization including high-grade epithermal gold-silver veins, polymetallic veins and structurally controlled bulk tonnage style gold systems.

Engineer gold mine

Phase I program is designed to expand the Engineer mine's high-grade gold mineralization and adjacent bulk tonnage targets along strike of previously identified structural corridors labelled Shear A and Shear B. These structures have been traced by geophysics and geochemistry for over three kilometres to the south of the past-producing Engineer mine. Phase I work will include an expanded soil and rock sampling program.

TAG property

As well, phase I work includes a rigorous core review and infill core sampling program at the TAG property six kilometres north of the Engineer mine. From 2006 to 2008, a total 11,520 metres of diamond drilling in 69 holes was competed at TAG ((Fekete and Simper (2009), Fekete and Skinner (2007); ARIS reports No. 30931 and No. 29581). Highlights from the historical diamond drilling results include those shown in the attached table.

Recent on site core re-examination at TAG has indicated that several drill intercepts crossing the identified mineralized trend were not fully sampled, and in some instances, samples were not collected adjacent to those hosting significant gold values. Once the infill and expanded drill core sampling is completed a detailed model of the TAG results will be produced to target areas for potential expansion of the gold mineralization and to facilitate completing an updated resource estimate for TAG.

Additional soil geochemical sampling will be completed at TAG as prior sampling returned anomalous gold and silver values uphill from the known mineralization indicating the potential for a subparallel second mineralizing structure.
