Benton Resources is a well-funded mineral exploration company listed on the TSX Venture Exchange under the symbol BEX. Benton has a diversified, highly prospective real estate portfolio and holds large equity positions in other mining companies that bring forward high-quality assets. Where possible, BEX retains net smelter return (NSR) royalties with long-term cash flow potential.

Benton is focused on advancing its high-grade Copper-Gold Great Burnt Project in central Newfoundland, which has a mineral resource estimate of 667,000 tonnes at 3.21% Cu indicated and 482,000 at 2.35% Cu inferred. The project has an excellent geological setting covering 25 kilometers of strikes and features six known Cu-Au-Ag zones over 15 kilometers all of which are open for expansion. Further potential for discovery is excellent given the large number of untested geophysical targets and Cu-Au soil anomalies. Phase 1 and 2 drill programs produced impressive results, including 25.42 m of 5.51% Cu, including 9.78 m of 8.31% Cu and 1.00 m of 12.70% Cu. Drilling in the South Pond Gold Zone, approximately 7.5 km north of the Great Burnt Copper-Gold Zone, has confirmed a robust gold mineralized system over 2.5 km with results of 74.20 m at 1.43 g/t Au and 43.75 m at 1.62 g/t Au and is open to expansion in all directions.
