Ambrex Reports Significant Results From Aripuana
Discovery
TORONTO, ONTARIO--Ambrex Mining Corporation today announced
extremely positive results for the second round of drilling at its
Volcanogenic Massive Sulphide (VMS) discovery on its 49
percent-owned Aripuana property in Mato Grosso, Brazil. The
drilling includes significant gold/copper and zinc/lead
intersections from the same VMS system.

The holes were all drilled in the 800-meter-long section to a
maximum depth of 200 meters where a preliminary zinc/lead
geological resource of 4 million tonnes has been outlined. Hole
DDH 14 was a 50-meter stepout to the west from DDH 7 (2.9 m at
11.1 percent zinc) and DDH 15 was 50 meters east of DDH 8 (8.7m at
13.3 percent zinc). Only three holes -- DDH 9, DDH 11 and DDH 13
-- did not intersect massive sulphides.
The results confirm extensive lateral continuity of the VMS
deposit. It must be noted that the lower part of DDH 15, the zinc
section below the 4-meter gold/copper intersection, cut more than
42 meters (138 feet) of significant sulphide mineralization (3.3
percent zinc), thus demonstrating the superb size potential of the
deposit. The very high-grade portion of DDH 15 with a Gross Metal
Value (GMV) US$165 per tonne over 5 meters was part of the
42-meter intersection.
The first phase of detailed magnetometry over the property
demonstrated that the sulphide-rich body dips sub-vertically and
is open at depth and along strike. The mineralized body is
interpreted to continue to at least 400 meters in depth, over
twice the depth of the current drilling program. The survey is
continuing along the complete 3.1-kilometer geochemical anomaly on
the property to define the lateral potential.
Hole DDH 12 encountered significant copper (5 percent) and gold
with a Gross Metal Value (GMV) of US$137 per tonne over 5.8
meters. This underscores the potential for a separate gold/copper
orebody in addition to the zinc mineralization. This is confirmed
by Hole DDH 15 and the gold/copper values previously reported in
DDH 5 and 6. Both the gold/copper and zinc/lead sections of the
VMS show that the mineralization is part of a large-scale body. A
1-meter-wide stringer in DDH 14 returned 37.3 percent zinc,
suggesting proximity to a more massive mineralized body.
Of the 15 holes drilled to date by Ambrex at Aripuana, 10 holes
have intersected massive sulphides related to this gold, copper,
zinc, lead and silver discovery. The section drilled by Ambrex
begins 700 meters east of the property boundary, where Anglo
American is carrying out a large-scale drilling program on a
reported polymetallic discovery.
