Stephens Trig shows promise

One of the largest mining tenement holders in the region says initial drilling results show potential for an open cut mine just north of the city.
Silver City Minerals said a shallow drilling program it conducted at its Stephens Trig prospect, 12 kilometres north of Broken Hill, had found zinc within 100 metres of the surface.
Managing director Chris Torrey told the BDT that the company was actively searching for a shallow deposit in the area as part of a joint venture with CBH Resources.
“The concept there is very simple; it is to find some shallow ore close to surface that could be mined easily and cheaply that could be taken to the CHB plant (in Broken Hill),” he said.
“Open pit mining costs significantly less than underground mining and it’s barely 12 kilometres out of town.
“That’s the kind of scenario we’re looking at.”
The company sunk five holes with up to nine per cent zinc found in one intersection that was drilled in area where no near-surface drilling had taken place previously.
It said further drilling was required to assess the extent and grade of the zone.
Silver City holds 1200 square kilometres of ground in the region and Mr Torrey said “without a doubt” the most prospective tenements were Stephens Trig and another, wholly-owned project further east called Razorback West.
“Razorback West looks like the northern extension, offset by fault, of Broken Hill line of lode. It’s just north of the Stephens Creek reservoir and there’s no outcrop.
“When we first looked at it there had been no drill holes in that area ... until we came along.”
He said Silver City found “some big geochemical anomalies” underneath the gravel but now wants to take a closer look at Razorback West along with Stephens Trig.
“We’re lining these up to drill within the next three months.
“The government actually funds drilling programs every year and we’re trying to get them to help us by drilling some deep holes out there.
“We’ll see whether we’ve been successful in getting that funding in June, I think.”
Shares in Silver City Minerals shot up this week after it announced it was also planning to search for lithium in the region.
Mr Torrey said the company also had an arrangement with another explorer, Impact Minerals, which would deliver it a 20 per cent stake in a lead, zinc and silver project that company holds.
“We’ve been plugging away at Broken Hill since about 2010 and we’ve been actively exploring on a lot of things.
“We have had some success but we haven’t found a deposit yet. We keep working at it because that’s what we do.
“If we could get something together especially with CBH (Resources), our partner on a number of projects, it would be ideal because you could bring it from 20 kilometres away, if it’s high grade, and you could put it through the mill.”
