Abitibi Metals boosts resource by 62% at B26 polymetallic deposit in Quebec
Indicated resources increased to 11.3 million tonnes from 6.9 Mt.
Impact Minerals Limited (ASX: IPT) announced that it has lodged two new applications for 100% owned exploration permits for minerals (EPMs) at its Blackridge gold project near Clermont in central Queensland, Australia.
In a press release, the miner said the applications are uncontested and upon grant, together with an existing granted EPMs and one fully granted mining lease, will cover an area of about 150 square kilometres.
“This will give Impact ownership of about 90% of the historic Blackridge goldfield which forms the southern half of the greater Miclere-Blackridge area that produced over 300,000 ounces of gold in the late 1800s and early 1900s,” the media brief states.
“The gold mined at Blackridge was in the form of coarse nuggets mined mostly underground from a two-metre thick conglomerate unit located at the basal contact (unconformity) of a sedimentary sequence of Permian age and an older sequence known as the Anakie Metamorphics.”

Impact’s new applications cover ground previously tested by reverse circulation drilling at Hard Hill and by reverse circulation and large diameter (95 cm) Calweld drilling at Pewt’s Hill.
According to the company, only the Pewt’s Hill area has been explored previously. It comprises a ridge of conglomerate that is 1,000 metres long and up to 350 metres wide that rises above the surrounding Tertiary basalt. The unconformity is present at surface on the eastern side of the ridge.
The Hard Hill license, on the other hand, covers the majority of the down-dip extent of the main conglomerate unit that was mined historically at Blackridge.
Two lines of evidence suggest that gold in this area occurs over a very large area of at least 2,000 metres down dip from surface outcrops of the unconformity to a depth of only 100 metres below surface, and for at least 1,200 metres along trend.
