One hole towards the northern end of the prospect returned 1 metre at 62.9 g/t from 129 metres, with the drill bit intersecting the Cutler structure and returning an expected high-grade result.
Grades recorded so far have strengthened the concept of northerly plunging gold mineralisation and confirmed the presence of a mineralised structure over at least 500 metres of strike.
Riversgold managing director Alan Kelly said the 62.9 g/t intersection was from one of the deeper holes drilled at Cutler to date and had significant implications for the potential size of the target.
He said regarding a previously drilled hole: “It looks like [the hole] did not effectively test the Cutler structure, which means the gold mineralisation remains open down-plunge to the north, potentially for a significant distance.”
Other highlights from the program include: 1 metre at 4.63 g/t; 3 metres at 1.29 g/t; and 10 metres at 0.85 g/t, including 3 metres at 1.44 g/t.
These results were intersected in a 30-metre wide zone of gold anomalism from 117-148 metres.
The hole that returned the high-grade intercept of 62.9 g/t also hit further mineralisation deeper down, intersecting 3 metres at 2.19 g/t from 145 metres.
A third hole encountered shallow high-grade oxide mineralisation with an assay of 4 metres at 5.31 g/t.
This hole also intersected the Cutler structure, returning further assays of: 5 metres at 0.88 g/t from 107 metres, including 2 metres at 1.53 g/t from 110 metres.
Riversgold has recently received a program of work approval for further follow-up drilling at Cutler, which will start following completion of its Alaskan drilling campaign.
It is one of several targets identified from historical surface geochemical surveys completed during the late 1980s to early 1990s.
