Aurumin reports ‘great assays’ at Mt Dimer gold project
Aurumin’s Mt Dimer project in WA was historically mined and produced more than 125,000oz gold during its life.
Western Australia gold explorer Aurumin (ASX: AUN) has returned what it describes as “high-grade results” from the first assays at its historic Mt Dimer project, located 120km northeast of Southern Cross.
The reverse circulation drilling at the previously unmined Lightning prospect included one hole that intersected two separate mineralised zones.
The first assayed at 16m at 4.44 grams per tonne gold, including 1m at 12.35g/t, and then another zone was intersected over 3m at 15.35g/t, including 1m at 36.2g/t.
Another hole returned 4m at 4.39g/t, including 1m at 14.98g/t.
Mt Dimer is a historic gold operation. It was discovered in 1987 — the year of the huge market crash that sidelined many mining projects — by the former major Western Mining Corporation.
Historic mining at average 6.4g/t
It was previously mined by the former Tectonic Resources between 1994 and 1997, when the gold price varied between US$300 and US$500 per ounce.
In all, 125,000oz was produced at 6.4g/t. However, mining did not include the Lightning deposit, the target of present drilling, but was, instead, carried out at the project’s Golden Slipper prospect.
Mt Dimer can be accessed from the Great Northern Highway and has an operational airstrip.
Aurumin managing director Brad Valiukas was positive about the latest drilling results.
“Some great assays from Lightning, both filling in a gap in the existing data and chasing some lateral extension to the north,” he said.
“The assays highlight the high-grade nature of mineralisation at Mt Dimer,” he added.
Aurumin has completed five reverse circulation drill holes at Lightning for 529m.
Potential new high-grade shoot
The program was designed to intercept northerly trending mineralised structures, predominantly along strike from historical work.
All holes were successful in intersecting the northerly structure, which comprises massive quartz veins.
However, other holes to the south, while unsuccessful in extending the southern-most shoot further south, included one that potentially identified a new high-grade shoot immediately to the north.
Aurumin also owns the Mt Palmer gold project, 15km from Marvel Loch in Western Australia.
It also hosts a historic mine, having been worked between 1934 and 1944, during which time it produced 158,000oz at an average 15.9g/t.
Aurumin is also looking for further acquisitions.
