2023 Diamond Drill Results Iron Lake Magmatic Sulphide Project

TSX.V: ETF·OTC: ETFLF·VANCOUVER, BC

Oct 11, 2023, Iron Lake option partner Tech-X Resources Inc. has provided Eastfield Resources Ltd.( TSX-V: ETF) the results of diamond drilling completed between June 29 and July 26, 2023 on the Iron Lake copper-nickel-cobalt-platinum-palladium – gold sulphide prospect located 45 kilometers northeast of the community of 100 Mile House, BC. A total of 1,680 m of diamond drilling was completed in 3 holes. Two holes targeted the semi-massive sulphide horizon), referred to as the Discovery Zone, while the remaining hole was directed toward a recent airborne geophysical anomaly in an area called the Northwest Zone. Holes were angled between -55 to -65 degrees and varied in length from 324 to 750 meters.

The following table summarizes significant results:

Hole IL-23-024 was drilled at the Discovery Zone to test a conductivity anomaly at a depth of 570 m down-dip of sulphide intersections in holes IL-22-012 and IL-22-013 drilled in 2022.  The hole was extended to 606 m after intersecting two narrow massive sulphide layers at 530.0 m and 537.0 m (two additional massive sulphide layers were subsequently intersected at 572.2 m and 576.9 m).  These mineralized layers were pyrrhotite dominant and pyrite dominant respectively confirming that the magmatic sulphide system in the Discovery Zone remains open to depth. Assay results for a 9.5 m interval spanning across both of these massive sulphide intersections graded 0.42% copper and 341 ppm nickel (569.0 m to 578.5 m).  This interval includes one sample which returned a copper value over limit (>1%).

Hole IL-23-025 tested near surface and deeper flat lying conductivity anomalies outlined in an airborne survey completed in 2022 at the Northwest Zone (approximately 3.0 kilometres to the northwest of Il-23-24).  This hole was completed at a depth of 750.0 m and predominantly intersected magnetite bearing pyroxenite consistently elevated in nickel with 24.1 metres grading 0.1% Ni.  No massive sulphide intervals were encountered.

Hole IL-23-026 was drilled towards IL-23-024 to target the up-dip projection of the massive sulphides intersected in IL-23-024.  A 0.3 metre massive sulphide layer was intersected at 216.0 m.  Results from this intersection yielded 0.65% copper, 0.1% nickel and 0.3 g/t palladium over 0.5 metre.

A number of single point (single core sample) anomalies were obtained in these three holes including gold to 677 ppb, platinum to 723 ppb and cobalt to 1,620 ppm. Five samples returned >30% iron and four >20% sulphur.

Drilling in 2023 has demonstrated that mineralization at the Discovery Zone extends to depth and that potential for a large Alaskan-type system exists.  The 2023 program did not evaluate the porphyry targets defined by extensive induced polarization surveys completed in 2021 and 2022. Further work will be required to test the Discovery Zone along strike and to follow-up on significant drill intercepts elsewhere on the Project.

Tech-X Resources Inc. is a private company headed by Haig Farris with geological oversight provided by Jim Dawson. Tech-X may earn an 80% interest in the Iron Lake property by completing a total of $12,000,000 in work and paying a total of $730,000 in option payments by June 15, 2029. A 51% interest becomes earned following exploration expenditures of $4,000,000 and option payments of $230,000 by Dec 31, 2025. Twenty-three diamond drill holes were completed in 2022.

Drill supervision, core logging and QC/QA was conducted by Archer, Cathro and Associates (1981) Limited, of Vancouver, BC. A total of 957 samples were analyzed in the facilities of ActLabs located in Kamloops BC using a multi-element procedure with an aqua regia digestion.
