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

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 @ 3.21% Cu Indicated and 482,000 @ 2.35% Cu Inferred. The Project has an excellent geological setting covering 25km of strike and boasts six known Cu-Au-Ag zones over 15km that are all open for expansion. Further potential for discovery is excellent given the extensive number of untested geophysical targets and Cu-Au soil anomalies. Phase 1 and 2 drill programs returned 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 at 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 of 1.43g/t Au and 43.75 m of 1.62g/t Au and is open for expansion in all directions.
