Resources Ltd (SGV) Mr William Fisher reports The company's richest
zinc/lead/silver intersection to date at the Aripuana volcanogenic
massive sulphide discovery in Brazil, a 4.3 metre intercept grading
14.13% zinc, 2.66% lead and 213.81 g/t silver. The significance of the
latest three holes is that the strike of the deposit has now been
extended to at least 225 metres. It also supports the results of earlier
geophysical work that suggested the deposit could extend a minimum
500 to 600 metres below surface. The deepest drill hole from the latest
results intersected ore-grade mineralization at nearly 300 metres. The
deposit remains open along strike in both directions and at depth. Full
results are as follows:

All three holes were collared to test the Valley deposit. To the west,
the company is also exploring a second deposit, known as the North
Ridge, which in preliminary drilling returned values as high as 5%
copper and 1.63 g/t gold across 5.8 metres. In the latest results, DDH
17 was a step-out 75 metres to the west of DDH 8, while DDH 18 was
a 50-metre step-out to the east of DDH 16, which as previously
announced, intersected 6 metres grading 16.1% zinc, 1.6% lead and
132.1 g/t silver. DDH 19 is the deepest hole to date and confirmed
mineralization reaches to at least 300 metres, or approaching 1,000
feet below surface. It was designed to test and now strongly supports
earlier geophysical work that the deposit has a depth extension of at
least 500 metres. The 90-metre mineralized envelope includes an
intersection with grades of 10.02% zinc, 2.56% lead and 47.3 g/t silver
across 2.91 metres. Most of the holes drilled so far indicate that the
VMS deposit displays hot zones of higher grade material at the upper
portion of each of the intersections, which confirms that there is
continuity to the higher grade portions of the deposit. The company
and St Genevieve Resources in joint venture have the right to earn a
70% interest in the project (Ambrex 49%, St. Genevieve 21%) from
Ourominas. The venture is well ahead of its obligations. (c) Copyright
