MISIMA Island minerals explorer Kingston Resources Limited has unvielled a new high-grade gold opportunity in its ongoing regional exploration campaign.
The company’s auger programme, undertaken over the Ara Creek prospect, has defined a gold anomaly more than 400m long and open along strike, with individual auger samples assaying up to 4.18g/t Au.
Kingston said its field team has also identified and surveyed five historic underground adits within the prospect area, rock chip samples from the entrances to these adits returned values as high as 8.45g/t Au.
The Ara Creek prospect, was identified by a review of historic work completed during the early stages of Placer Mines’ exploration in the area, reinforced by structural work Kingston completed earlier in 2018.
The prospect is located within the Misima North area on the interpreted northern continuation of the Umuna Fault Zone (UFZ). The southern end of the UFZ hosts the bulk of the current 2.8Moz Misima JORC Resource.
The northern extension is relatively under-explored, despite having similar scale to the historic Umuna area, with well over 3km of prospective shear, historic underground workings, and strong geochemical indicators.
“These auger and rock chip values again highlight the vast and immediate exploration upside that exists across Misima,” Kingston’s managing director Andrew Corbett said.
“We are only just scratching the surface in terms of exploration at Misima and it is becoming clear that there are still multiple zones and new areas across the island that remain undiscovered. The potential of our total project area is just starting to be realised.
“With rock chip sampling, trenching, auger drilling and diamond drilling, we expect ongoing results across the coming months.”
Mr Corbett said the Ara Creek assay results are significant for a number of reasons:
• The area was a focus for historic underground mining pre-WW2;
• It sits roughly in the middle of the Misima North region, 2.5km north of the Umuna pit and 2.2km from
the north coast at Siagara village, straddling the Umuna Fault Zone in an area interpreted to be a
flexure in the strike of the shear; and
• Exploration by Placer identified significant surface mineralisation in soil and channel sampling between
1992 and 1994.
Ara Creek was prioritised by Kingston after a systematic review of all available data. Reports of mineralisation in the area from as far back as 1939 provide an indication of the area’s potential, and this information is supported by conventional soil sampling completed by Misima Mines in 1992, channel sampling in 1993-94, and a number of historic drill holes.
Drilling results included intersections such as 10m @ 3.20g/t Au from surface in MNR515 and 12m @ 2.05g/t from surface in MNR889. Mapping by Misima Mines also shows a subtle right-hand flexure in the shear, making it an ideal structural position for mineralising fluids.
The company says the recent auger programme has confirmed the presence of significant gold anomalism at surface on the east side of the Umuna Shear, however none of the historic drilling has properly tested the shear itself. Kingston intends to continue sampling and mapping the prospect to fully determine the extent of surface mineralisation, with a view to drill testing in 2019.
