It acquired the project - adjacent to its Goldwedge property which has a fully permitted underground mine and mothballed mill - from Kinross Gold affiliates in March, for US$100,000 and $150,000 in shares.
The headline intercept was from the previously-mined West Pit area.
All five assays to date from the East Pit area intersected gold mineralisation, including 6.1m at 4.95g/t.
Scorpio said 11 of 31 planned holes had been completed.
The project is about 17km south of Kinross' Round Mountain mine.
Scorpio said its now-consolidated holdings in the Manhattan mining district gave it control of 2,457ha and a large land position along the Reliance Fault Zone.
Scorpio last month regained 100% of its Mineral Ridge gold project in Nevada after Titan Mining terminated an earn-in option.
Mineral Ridge produced 603 ounces of gold and 330oz of silver in the March quarter through a dwindling, residual heap leach operation.
Scorpio had $4.1 million in working capital at March 31.
Its shares (TSXV: SGN) gained 10% yesterday to close at C11c, towards the bottom of a 12-month span, valuing it at $12.3 million (US$9.7 million).
