Drilling returns 176m gold-copper intersection

• Drill hole PTDD020 returns 176m grading 0.50 g/t Au-Eq2 from surface
• Mineralisation at Porotillo expands to 520m x 230m
• Assays pending for additional holes and trenches before resource update

Sunstone Metals Ltd. has announced that drill hole PTDD020 at the Porotillo discovery within the Bramaderos Gold-Copper Project in Southern Ecuador has returned an intersection of 175.76 meters grading 0.50 g/t Au-Eq from surface. This result significantly expands the known mineralised footprint at Porotillo to 520 meters by 230 meters. The mineralisation is open at depth and to the south. The area, along with other recently identified mineralisation, will be included in the planned resource update for the December quarter. Assays are pending for additional holes and trenches, which will be received during August and early September.
