The result was among the latest from drilling to test the COD vein and also included 0.46m at 167.5g/t gold, 1,370g/t silver and more than 500g/t tellurium.
The company said the 2.05m intersection was a fresh highlight, ahead of an earlier 2.1m at 14.62g/t gold, 150.2g/t silver and 102g/t tellurium also at the COD vein.
GGX entered an option agreement to acquire a 100% interest in Gold Drop in mid-2016.
The company, formerly Revolver Resources, reported a net loss of C$1.9 million (US$1.4 million) at March 31 as exploration expenses increased.
It raised C$395,600 (US$300,000) in June then a further $362,000 (US$276,000) last month in private placements, saying it had sufficient funds to complete its planned summer exploration programme at Gold Drop.
Shares in the company have slid from C20.5c a year ago to 7c last month.
They rose 1.5c, or more than 13% yesterday, to 12.5c.
