Impact Minerals Encounters Visible Sulphides at Little Broken Hill Gabbro and Red Hill

THE DRILL SERGEANT: Impact Minerals reported visible sulphide mineralisation being intersected in diamond drill core for the first time at Little Broken Hill Gabbro and Red Hill prospects at the company’s 100 per cent-owned Broken Hill project platinum group element (PGE)-copper-nickel project in New South Wales.

The fun kicked off at the Little Broken Hill Gabbro (LBHG), where hole RWIPT016 was drilled between two traverses of previous RC drill holes at Rockwell, which covers the northern third of the LBHG and where Impact has discovered very encouraging PGE-nickel-copper mineralisation over at least 1,500 metres of strike within the very poorly explored basal ultramafic unit.

Hole RWIPT016 intersected the basal 95m of the LBHG which comprises 71 metres of gabbro that overlies the target basal ultramafic unit which, in this location is 24m thick true width.

At Red Hill, two diamond drill holes were completed to follow up a previous drill intercept in RC hole RHIPT34, testing the southern contact of the Red Hill chonolith intrusion.

The new diamond holes intersected the basal contact of the intrusion at a depth of about 450m below surface.

“It is great to get a first look at the high tenor PGE-dominant mineralisation at the base of the Little Broken Hill Gabbro,” Impact Minerals managing director Dr Mike Jones said in the company’s ASX announcement.

“The textures indicate the mineralisation is directly associated with magmatic processes at the base of host ultramafic unit and which have the potential to form a massive sulphide deposit in the right trap such as a basal channel structure as we have already discovered at Platinum Springs.

“We believe that such a channel may be close by and we look forward to getting a down hole EM survey underway to identify possible targets for massive sulphide as quickly as possible.

“A down hole survey is also planned at Red Hill where fine disseminated sulphide has been recognised in many places in the core and to determine if massive sulphide could be present below the base of the intrusion which has been faulted off.

“We will have to wait for assays to confirm the PGE grades and of course there are significant delays in laboratories across Australia at present.

“These delays have also affected the delivery of the assays from our Apsley drill program, despite promises from the laboratory, with further batches due by mid-June.

“We are very encouraged by the core at Broken Hill as it confirms our belief that the LBHG may potentially contain a significant reservoir of PGE’s and possibly nickel and copper.

“We have to remember that this is the first ever drill program to test the basal ultramafic unit and yet every drill hole that has intersected it has returned some level of mineralisation.

“It is evident that there is very significant potential along the entire length of the 6.5 kilometres long intrusion and we are gearing up towards a major follow up drill program at all of our prospects there as soon as practicable given we already have statutory permissions for a number of drill holes in place.

“We are in discussions with drill contractors and note that drill availability is much more reasonable in New South Wales than elsewhere in Australia.”
