The company reported its auger drilling program over the Ara Creek prospect defined a gold anomaly that was more than 400 metres long and open along strike.
Kingston reported its field team had surveyed five historic underground adits within the creek area, with rock chips from the entrances to the horizontal passages to the mine grading up to 8.45 g/t gold.
The area was mined underground before World War II and is about 2.2km from the north coast at Siagara village, 2.5km north of the Umuna pit and in the middle of Misima North region.
Placer Mines explored the area between 1992 and 1994, undertaking soil and channel sampling at Ara Creek area and finding significant surface mineralisation.
Misima Mines also undertook conventional soil sampling at the site and drilled intersections such as 10 metres at 3.20 g/t gold from surface in one hole and 12 metres at 2.05 g/t from surface in another.
Ara Creek prospect is in the Misima project’s Misima North area on what is interpreted to be a northern continuation of the Umuna Fault Zone (UFZ).
UFZ’s southern end hosts most of the project’s 2.8 million-ounce Misima JORC resource.
The company told the market: “The northern extension is relatively under-explored, despite having similar scale to the historic Umuna area, with well over 3 kilometres of prospective shear, historic underground workings, and strong geochemical indicators.”
Kingston managing director Andrew Corbett said: “These auger and rock chip values again highlight the vast and immediate exploration upside that exists across Misima.
“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 company will continue to share results from its rock chip sampling, trenching, auger drilling and diamond drilling efforts over the coming months.
