Project Overview
The Iron Lake property covers 8,035 hectares located 50 km northeast of the community of 100 Mile House in south-central British Columbia, within rocks of the Triassic-Jurassic Quesnel Terrane. The property is under option to Tech-X Resources Inc., a private company that in 2023 — having expended $4 million since 2021 — earned a 51% interest in the project, with Eastfield retaining a 49% interest. The Iron Lake ultramafic complex, occupying the northern half of the property, has received the vast majority of exploration, including 43 drill holes (8,558 metres). The project is fully permitted for drilling until May 2, 2027.
Geology & Target Model
Rocks on the property are predominantly volcanic, volcaniclastic, and intrusive (both alkalic and calc-alkalic), in contact with an ultramafic body several square kilometres in extent. The ultramafic complex corresponds to both very strong regional magnetic and regional airborne gravity highs and hosts disseminated and massive-sulfide styles of mineralization. The southern half of the property, outside the ultramafic complex, has scarce outcrop of diorite and feldspar porphyry. The Iron Lake ultramafic complex is comparable to the Turnagain Ultramafic Complex of northern British Columbia and the Lac des Isles palladium deposit in Ontario.

Exploration Highlights
- 01
43 drill holes (8,558 metres) completed, focused on the Iron Lake ultramafic complex occupying the northern half of the property.
- 02
In 2022, a 60-kilometre induced polarization survey outlined a very strong anomaly over an area measuring 4 by 3 kilometres — a compelling untested porphyry copper-gold target.
- 03
An average of eight samples of disseminated mineralized olivine pyroxenite rubble (from one select area) is 0.71% copper, 0.70 g/t gold, 0.20 g/t palladium and 0.13 g/t platinum.
- 04
Significant massive-sulfide drill intercepts from at least four horizons, including hole IL05-03 with 17.0 metres grading 0.34% copper and 23.7% iron, and hole IL23-24 with 9.5 metres grading 0.42% copper.
- 05
The ultramafic complex corresponds to both very strong regional magnetic and regional airborne gravity highs.
- 06
Historical drilling returned cobalt values in massive sulfide reaching 0.14% over 1.4-metre core intervals, with select grab samples reaching 0.35% cobalt.
- 07
Historical exploration on the southeastern side of the property returned soil values up to 12.0 g/t gold and select rock samples up to 74.9 g/t gold from an area of arsenical gold mineralization.

Ownership, Partner Status & Next Steps
Ownership & Option Status
Under option to Tech-X Resources Inc., a private company. In 2023, Tech-X Resources — having expended $4 million since 2021 — earned a 51% interest in the project. Eastfield Resources Ltd. retains a 49% interest. Tech-X may earn an additional 29% interest, for a total interest of 80%, subject to the terms of the option agreement.
Planned Next Steps
The project is fully permitted for drilling until May 2, 2027. The 4 by 3 kilometre IP anomaly on the southern half of the property remains a compelling untested porphyry copper-gold target.
