MOROBE miner Niuminco Group Limited has returned some positive early results from a new shallow drilling program at the Enterprise vein system (Chimney Area) at Edie Creek.
The program was designed to enable the establishment of an initial JORC Resource at the Enterprise vein system and to define potential sources of high grade material to feed an upgraded wet gravity concentrating plant at the rate of 50 to 60 tonnes per day.
An interim report on the completion of the initial three drill holes found that each of the holes contained a higher grade vein section conforming to the predicted west-dipping vein model
Best results included intersections of 5.4m at weighted average of 2.97g/t gold and 94g/t silver from 8m depth; including: 0 2m at 6.89g/t gold and 195g/t silver from 10m, 9m at weighted average of 1.07g/t gold and 62g/t silver from 12m, including; 0 1m at 4.06g/t gold and 21g/t silver from 13m and 3.4m at weighted average of 2.03g/t gold and 143g/t silver from 35m; including 2.1m at 3.04g/t gold and 167g/t silver from 35m.
Niuminco’s managing director, Tracey Lake said the program was off to a good start.
“Our geologists are very pleased with the results and grades so far despite some core loss, with the three holes achieving expected intercepts with the predicted vein system,” Mr Lake said.
The planned exploration program comprises drilling a total of approximately 350 to 500 metres in 10 angled diamond core drill holes spread over five drill platforms utilising one of Niuminco’s drill rigs and crew.
Niumino is hoping to resurrect the historic Enterprise Mine which was developed immediately prior to World War II, but no production occurred. Detailed underground sampling was reported in 1940 prior to abandonment due partly to the Japanese invasion of New Guinea and partly to a flooding incident at the nearby Edie Mine. The mine saw substantial level development but no stoping and production, so that there is ore defined by sampling that was never exploited.
Calculations by Mincor Resources NL in 2013 established potential for 35,000 ounces in four adjacent blocks.
Niumino’s immediate target at Enterprise is the shallow exposure at the southeast end of the lode in a Block described as EP-1a where potential for 1,000 ounces was calculated by Mincor Resources NL. This was based on surface channel sampling over a 60m section, and a 100m section on the Level 1 development drive.
