Struggling to attach a link, however if you google
"byron reef gold drill results" , click on the 2nd link down. It's a presentation from 2nd February 2019, and it goes through the mining history of Bailleston & Creswick and surroundings areas. Apologies for those who have seen this, but WOW! first time I've come across it, and it's an interesting read. I've attached a couple of snippets from the article below
"In contrast to Avoca,
the Bailieston area has
a modest historical production history from alluvial and vein quartz mines. Byron Reef, a major
producing reef, was discovered in 1864 by a prospector searching for alluvial gold. At its point of
discovery, the reef was only 25 mm wide, but widened to over 6 m at depth. The deepest early shaft
exploited Byron Reef to over 100m. There are no surviving records of early production from the reef, but
State government records indicate that grades ranged from 30 g/t Au to 280 g/t Au prior to closure of
the shaft. "
"The most significant recent discovery was made by Perseverance Corporation Ltd, leading to the
development of the Hill 158 open-cut gold mine, 7 km east of Nagambie and approximately 10 km east
of the Bailieston project. This was a low-grade, bulk mining stockwork or layered vein structures and
operated. The mine was started in 1989 and 132,000 ozs of gold was obtained from the Nagambie Hill
158 mine through the 1990s, an amount that exceeds the sum of all gold production in the district prior
to that year. "
"GMK’s drilling near the main shaft hit old stopes, while further south a narrow, high grade intercept was
encountered (BLP140: 3 m at 14.74 ppm Au). At the Maori reef, drillhole BLP136 intersected 2 m at 17.2
ppm Au from 44 m downhole. Other holes encountered stopes (BLP008 and BLP172), with remnant
mineralisation intersected prior to the stopes."
If I'm correct, the Maori reef is the next stop for MIDAS so seeing grades of 17 g/t is encouraging
"The Black Cat prospect is immediately south of ground recently applied for by Newmont Exploration and
contains 220m of historical workings along three known lines of quartz reef. Strong gold-in-soil
anomalism in some areas indicates unworked reefs may remain to be discovered, and rock chip
sampling of quartz-poor material indicates potential for disseminated gold. Rock chip samples at Black
Cat have returned encouraging grades up to 11.3g/t gold.
"The Dimocks Main Shale may therefore provide an opportunity to bulk mine a series of auriferous veins
across the width of the shale. Only two holes have been drilled to test the DMS within EL006184, both in
the 1990s. The results of this drilling included an intercept of 2m@ 12.28 g/t Au. The best previous drill
intercept into the DMS to the south of Creswick was a rather stunning 2m@ 176 g/t Au.
Another great reminder what we're currently dealing with :D Happy weekend everybody
