Slide 6: Big Sandy Snapshot
BIG SANDY SNAPSHOT In 2017, exploration data from the Perseverance project showed that the truncated hangingwall had been transported farther than was expected. Bell used this information to refine where the hangingwall from Diamond Joe Peak might reside Perseverance Analogue 100% owned 2020 S
Slide 7: Exotic Copper
EXOTIC COPPER Several unusual copper occurrences believed to be linked to a shallowly covered porphyry copper deposit. Copper minerals found at Big Sandy are hosted in geologically recent terrace gravels of the Big Sandy River, in young faults that have recently conducted groundwater up to the sur

Slide 10: Drilling Program
DRILLING PROGRAM Bell’s objective was to locate the truncated top of the Diamond Joe porphyry system which we believed had been transported approximately 12 -15 km ENE onto the Big Sandy Claim block. Based on the size of the target, 4 drill sites were permitted with approximately 1.6 km spacing be

Slide 12: Drilling Program
DRILLING PROGRAM With drill hole BS-1 successfully locating the truncated system on the Big Sandy Claim block, Bell is now focused on locating the potentially mineral rich copper shell. Drill hole BS-2 was located approximately 1.6 km south of BS-1. BS-2 revealed fringing, scattered propylitic a

Slide 15: Drilling Program - Drill Hole BS-3 Copper Sulfides
DRILLING PROGRAM - Drill Hole BS-3 Copper Sulfides The 200-meter interval between 1302 meters and 1502 meters returned an average grade of 0.42 percent copper (8.4 lbsCu/st) and 2.4 grams of silver per tonne, including 54 meters from 1445 meters to 1499 meters grading 0.67 percent copper (13.4 lbs

Slide 17: Drilling Program - Drill Hole BS-3
DRILLING PROGRAM - Drill Hole BS-3 From an inclined depth of 1502 meters to the bottom of the hole at 2026.33 meters, sulfide minerals were dominated by pyrite, accompanied by minor chalcopyrite, tennantite, sphalerite, and trace molybdenite, with pyrite averaging Core from BS-3 (1927.5 m) showing
Slide 18: Metallurgy - Drill Hole BS-3
Metallurgy - Drill Hole BS-3 Conventional froth flotation approach was found to be successful at recovering and concentrating the value minerals. Batch test copper recovery of 82-84% into a concentrate grade of 25% Cu was achieved. Mineralogically, 75% of the copper in the sample was chalcocite, 1
Slide 19: Metallurgy - Drill Hole BS-3
Metallurgy - Drill Hole BS-3 Low molybdenum feed grade made it difficult to produce a Mo concentrate, but in a best test, a Mo cleaner concentrate graded 20.7% Mo. Further test work on larger amounts of sample is required to improve upon Mo results. The rhenium grade was assayed in a lower grade
