Goldbrook Ventures has discovered a significant and apparently extensive sulphide system at the Echo One prospect which is part of the Raglan Project in northern Quebec, Canada.
The discovery was made as part of the 2010 diamond drilling program at Raglan, which is an option-joint venture agreement with Jilin Jien Nickel Industry Co, of Jilin, China.
The Echo Ultramafic Complex was identified as an under-explored and high priority target during 2010 pre-season targeting. Historical trenching and limited shallow drilling by previous operators had sampled narrow intervals of high grade nickel-copper-palladium sulphides associated with a strike-extensive gossan at Echo One.
During the 2010 drilling campaign, Goldbrook completed 32 diamond drill holes totalling 6193 metres on the Echo One prospect. These holes were drilled on sections along the southern contact of the Echo One complex over a strike length of 1600 metres.
One hole was lost due to permafrost conditions and 31 intersected sulphide mineralization located both within, and at the contact of, a large composite ultramafic complex.
Drilling to date demonstrates a potential for a major new sulphide zone at Echo One which is about 5km west of Goldbrook's Bravo B4 deposit and 7km to the east of Goldbrook's Timtu deposit.
Ongoing interpretations of the geology, geophysical responses and geochemistry of the prospect have already indentified critical structural controls on thicker parts of the mineralized zone and have defined preliminary drill targets for a 2011 follow-up program.
Highlights of the Echo One drilling assay results received to date include 2.71 metres from 55.13 metres with an average grade of 1.09% nickel, 0.87% copper and 5.30 grams/tonne platinum group metals + gold; 6.89 metres from 80 metres with an average grade of 1.41% nickel, 1.03% copper and 8.33 grams/tonne PGE + gold; and 4.60 metres from 131.40 metres o with an average grade of 0.54% nickel, 0.67% copper and 2.42 grams/tonne PGE + gold, and a second 4 metre intersection from 151 metres in this hole with an average grade of 1.59% nickel, 1.76% copper and 4.33 grams/tonne PGE + gold.
