Sheffield Resources hits best grades yet at Thunderbird

/in /by

THE DRILL SERGEANT: Sheffield Resources (ASX:SFX) has announced the best drill results it has achieved so far from the company’s Thunderbird heavy mineral sand (HMS) deposit, located near Derby in the Canning Basin region of Western Australia.

The results were part of the third batch of assay results to be reported from the 2013 aircore drilling program.

The results relate to 63 infill and extension drill holes, which returned thick, high-grade intervals, including: (using a greater than 2 per cent HM cut-off, including greater than 7.5 per cent HM cut-off).

–    55.5 metres at 10 per cent heavy minerals (HM) from 4.5 metres (THAC352), including 19.5 metres at 21 per cent HM from 12 metres;

–    46m at 12.4 per cent HM from 30.5m (THAC404), including 28m at 17.9 per cent HM from 32m;

–    52.5m at 8.37 per cent HM from 9m (THAC348), including 18m at 17.2 per cent HM from 16.5m;

–    40.5m at 11.7 per cent HM from 24m (THAC403), including 24m at 16.1 per cent HM from 25.5m;

–    58m at 9.61 per cent HM from 27.5m (THAC400), including 32.5m at 14.5 per cent HM from 29m;

–    46.5m at 9.73 per cent HM from 3m (THAC370), including 27m at 14.3 per cent HM from 12m; and

–    62.5m at 9.14 per cent HM from 33.5m (THAC401), including 29.5m at 13.3 per cent HM from 36.5m.

Sheffield said the latest results confirm the presence of a thick continuous zone of high-grade mineralisation (greater than 7.5 per cent HM) trending in a north-south direction through the deposit, which is considered to be at least 6km long and 2.5km wide.

“The Thunderbird drill results continue to significantly exceed our expectation, which is highly-encouraging for our scoping study and further exploration work,” Sheffield Resources managing director Bruce McQuitty said in the company’s announcement to the Australian Securities Exchange.

“These results delineate a large, thick accumulation of high-grade mineralisation, which is a pleasing new development from this year’s drilling.

“The Thunderbird deposit currently extends over an area of seven kilometres by four kilometres.

“The broad high-grade zone is now defined over an area of six kilometres by 2.5 kilometres and contains some extremely high-grade material.

“Our scoping study will focus on optimising this substantial zone of high-grade mineralisation during the early production years.”
