Mamba Exploration is hitting high-grade gold just about wherever it sinks a hole at the Calyerup Creek gold project in WA.

The first results from the company’s first RC drilling campaign at the project near Jerramungup in the Great Southern region of the mining State are in and Mamba (ASX:M24) has released an impressive set of hits to start off 2022.

Seven of the eight holes Mamba completed last year at Calyerup Creek came up trumps with significant and shallow gold strikes including a tasty intercept of 15m at 2.20g/t gold from just 1m deep, including 3m @ 3.53g/t in 21CCRC002.

Other results included:

  • 15m at 2.08g/t gold from 3m, including 2m at 9.74g/t gold in 21CCRC007
  • 16m at 1.05g/t gold from 18m, including 3m at 2.58g/t gold and 1m at 2.74g/t gold from 43m to EOH in 21CCRC003
  • 2m at 2.70g/t from surface and 11m at 1.38g/t gold from 7m in 21CCRC004
  • 10m at 1.34g/t gold from 20m in 21CCRC005; and,
  • 2m at 2.59g/t gold from 19m in 21CCRC006.

“It is very pleasing to report shallow and consistent widths of high-grade gold mineralisation in seven of the first eight RC holes completed by the company at the Calyerup Creek Gold Project,” Mamba managing director Mike Dunbar said.

“To intersect consistent and significant widths of high-grade gold mineralisation from such shallow depths along a strike length of around 140m at the Southern Prospect is a great result. Importantly this is just the start of the programme.”

An open book

Mamba’s tenure at Calyerup Creek, where significant gold readings have been recorded in drilling and soil sampling in exploration dating back to the late 1980s, is an open book for gold exploration.

Comprising a massive 2800m long strike target across two soil anomalies each longer than 1400m, Dunbar says the drilling results represent less than 5% of its strike potential.

Even more stark, the depth extent of the potential deposit is completely open below just 30m and unlike many new gold discoveries in WA which are hidden under deep cover, looks to be mineralised very close to surface.

Only 8 of the initial 50 holes planned by Mamba have been drilled, with a rig expected to get back to work on January 21 to complete the program.

It comes alongside results from additional soil sampling to infill the sample dataset at Calyerup Creek.

That picked up peak results of 2.8g/t from the southern trend and 1.3g/t from the northern trend.

Those areas remain undrilled, prompting a fast-moving Mamba to submit a program of works to the WA mines department to add another 100-hole program over the 50-hole drill already approved.

“This drilling will initially focus on the shallower portions of the programme,” Dunbar said.

“Additionally, to have identified high grade gold up to 2,800ppb (2.8g/t gold) in the southern trend and 1,300ppb (1.3g/t gold) from the northern trend in the infill soil sampling programme is a great outcome.

“This infill data has better defined the anomalous gold trends and an additional PoW for the project has been submitted for approval by DMIRS to allow additional drilling to be completed. Once approved, the additional drilling will be undertaken as a priority.”

Mamba active on multiple fronts

As far as WA explorers go, Mamba has a diverse set of exploration assets.

Along with Calyerup Creek in the State’s south, Mamba also owns the Ashburton gold project north of Carnarvon in the Mid-West and projects in the Kimberly that are prospective for copper-nickel and PGE mineralisation.

Along with Calyerup Creek, Mamba has RC drilling ongoing at Black Hills in its Darling Range project, a 6km ultramafic trend just 30km northeast of Chalice Mining’s (ASX:CHN) world class Julimar nickel-copper-PGE discovery.

Drilling late last year identified multiple zones of sulphide mineralisation in the second hole at the priority target with lab results still to come.
