Cornerstone Capital Provides Cascabel Exploration Update – Holes 19 to 25

Cornerstone Capital Resources Inc. (“Cornerstone” or “the Company”) (TSXV:CGP) (FRANKFURT:GWN) (BERLIN:GWN) (OTCBB:CTNXF) announces the following project update for the Cascabel copper-gold porphyry joint venture exploration project in northern Ecuador.
As quoted in the press release:

• HIGHLIGHTS:

• Hole 19 final results return:

  • 1344m @ 0.44 % copper and 0.28 g/t gold from 268m (0.62% CuEQ at 0.10% CuEq cut-off, true width: 484m), including:
    • 980m @ 0.55 % copper and 0.36 g/t gold from 514m (0.78% CuEq at 0.30% CuEq cut-off, true width: 353m), and
    • 552m @ 0.68 % copper and 0.45 g/t gold from 822m (0.96% CuEq at 0.5% CuEq cut-off, true width: 199m).

• Hole 20R intersects strongly mineralized porphyry clasts within hydrothermal breccia returning open ended intersection of:
  • 498.4m @ 0.20% copper and 0.15 g/t gold from 844m (0.29% CuEq at 0.10% CuEq cut-off, true width: 130m), including:
    • 126.0m @ 0.27 % copper and 0.32 g/t gold from 1136m (0.47% CuEq at 0.30% CuEq cut-off, true width: 33m), and
    • 44.0m @ 0.27 % copper and 0.58 g/t gold from 1202m (0.64% CuEq at 0.50% CuEq cut-off, true width: 11m).

• Hole 21 intersects copper sulphide mineralization from around 685m to 1610m depth. Assay results for Hole 21 are expected in late April 2017.

• Hole 22 intersects copper sulphide mineralization from 253m to approximately 1150m depth. Assay results for Hole 22 are expected early in April 2017.

• Hole 23R intersects hydrothermal breccia and strong phyllic alteration, with the presence of mineralized porphyry clasts in parts of the breccia. Hole 23R, at a current depth of 277.0m, is planned to intersect deep untested pockets of mineralization up to 1800m below surface and has a planned hole depth of at least 2000m.

• Hole 24 continues drilling at Alpala Southeast, at a current depth of 552.0m testing some 570m to the southeast of Hole 23R. Hole 24 is planned to extend the known mineralized corridor at Alpala to some 1150m from Hole 13 in the northwest.

• Hole 25 continues drilling at Hematite Hill, at a current depth of 377.7m testing some 250m to the southeast of Hole 23R. To date Hole 25 has intersected hydrothermal breccia with strong phyllic alteration and trace chalcopyrite mineralization, and has a planned hole depth of 2000m.

• A 4th man-portable rig will arrive at site early in April 2017. Arrival of Rigs 4, 5, 6 and 7 over the coming two quarters will also see drill testing expanding to Alpala East, Alpala West, Carmen, Triviño and Aguiñaga by mid-year.
