THE DRILL SERGEANT: Black Range Minerals has completed its maiden drilling program at the Hansen and Picnic Tree uranium deposits in Colorado, USA.
Black Range completed a total of eight diamond core holes at the Hansen deposit for 1,741 metres while a further three diamond core holes for 170 metres were completed at the Picnic Tree deposit.
This program was conducted by the company in order to obtain additional geological, geotechnical, metallurgical and hydrological data.
Black Range said the data acquired by the drilling prgram will be used to update previous feasibility studies that were undertaken into the development of the Hansen deposit during the early 1980s.
Analytical results from recent drilling at the Hansen deposit have been reported previously.
– 11.1 metres at 0.111 per cent uranium equivalent, including 4.1 metres at 0.165 per cent uranium equivalent, and 1.8 metres at 0.200 per cent uranium equivalent;
– 1.7m at 0.138 per cent uranium equivalent;
– 24.8m at 0.070 per cent uranium equivalent;
– 13.4m at 0.063 per cent uranium equivalent;
– 33.5m at 0.061 per cent uranium equivalent, including 10.1m at 0.093 per cent uranium equivalent, 4.3m at 0.100 per cent uranium equivalent; and
– 1.5m at 0.171 per cent uranium equivalent.
According to Black Range the recent drilling carried out at the Picnic Tree deposit confirmed the presence of shallow, high-grade mineralisation.
– 6.1m at 0.203 per cent uranium equivalent, from 40.5m, including 4.3m at 0.277 per cent uranium equivalent, from 41.2m.
“It is noted that numerous holes drilled during the recently completed program were located primarily to evaluate geotechnical conditions, rather than to evaluate resource grade, thickness and continuity, which has been well defined with the abundance of previous drilling data,” Black Range Minerals said in its announcement to the ASX.
“Representative ore samples from both the Hansen and Picnic Tree deposits are now being collected.
“These will be sent to suitable laboratories for metallurgical test work.”
Black Range has now commenced mine design work for both deposits which it said was an integral part of updating the historic feasibility study and determining the optimal development path for the project.
