Ban Phuc Nickel Project Drilling Completed
Asian Mineral Resources Completes Ban Phuc Nickel Project Drilling
Asian Mineral Resources Limited (TSX Venture “ASN”) announced today further results from its recently completed drilling programme on the Ban Phuc Nickel (sulfide) Project in Vietnam. Since March 2004, Asian Mineral Resources Limited (“AMR”) has completed drilling of 73 holes for a total of 13,661 metres in a programme designed to explore resource extensions and in-fill the main Ban Phuc nickel deposit.
Significant Results (down-hole intervals) include:
BP04-53 2.80 metres at 6.38% Nickel and 2.00% Copper
BP04-51A 3.40 metres at 3.40% Nickel and 1.73% Copper
BP04-55 49.2 metres at 0.61% Nickel and 0.07% Copper
BP04-55A 22.0 metres at 0.68% Nickel and 0.11% Copper
BP04-61 17.8 metres at 0.54% Nickel and 0.04% Copper
“The completion of this comprehensive drilling programme, on time and on budget, is a milestone”, said Mr David Woodhouse, President and CEO, “We now have the base data necessary to prepare a definitive resource estimate for our feasibility study”.
Work is progressing rapidly on updating the geological model and validating the database in preparation to undertake a new revised resource estimate that will incorporate the new drilling data. A previously announced resource estimate (September 17, 2004) incorporated results from the first stage of open-pit targeted drilling (27 holes for 2,962 metres) and does not yet incorporate the 10,699 metres of additional drilling completed to date. Assay results for the last 11 holes are pending.
AMR is pleased to report the timely completion of this phase of its programme of in-fill, confirmatory, and extensional target drilling on the Ban Phuc massive sulphide vein structure and the lower grade disseminated ultramafic intrusive zone. Good progress is being made in understanding the structural and geological controls of these mineralised types.
Downhole Surveying Programme An independent contractor has completed a comprehensive down hole gyroscopic surveying programme on all the holes drilled in this recently completed campaign. Because the deposit contains magnetite and pyrrhotite, a down hole ‘gyroscopic’ survey tool was used as it is unaffected by local magnetic variations which would otherwise cause difficulties with conventional down-hole survey techniques.
Previously, a paucity of down hole survey information meant that the Company’s independent geological consultants were not able to classify and report any measured resources. These hole positioning uncertainties have now been eliminated which clears the way for the Company’s next resource estimate to include the full spectrum of resource classification categories. In addition, several drill holes from the recent campaign have been used as verification holes to confirm the positioning on some key pre-2004 drilling.
Geotechnical Drilling AMR’s independent geotechnical consultant, Knight Piesold, have supervised the completion of 16 triple-tube diamond core holes. Six holes were drilled at strategic locations in an area reserved for the proposed tailings storage facility. Seven holes have been completed over two potential plant site locations and three holes completed over an area to be reserved for a small water storage and sediment catchment barrier. This data is being processed and compiled for inclusion in the Company’s project assessment.
Massive Sulphide Zone Hole BP04-53 confirmed the down dip depth continuation of the high grade intercept previously intersected and reported (Nov. 9, 2004) from Hole BP04-49 (down hole 7.9 metres at 5.16% Ni and 1.67% Cu). These intercepts successfully confirm the presence of a high grade mineralised chute which remains open and untested down plunge to the west. Future drilling will test the down plunge continuity by systematically stepping out on sections further to the west. (Refer Table 1 and attached diagrammatic long section for details).
In-fill drill hole BP 04-51A confirmed the lateral and depth extents of the higher grade sulfide mineralisation on section 49950E within a previously delineated inferred resource block for which we had limited drilling information and were reliant on a few historical drill holes. This hole supports the evolving geological model by demonstrating continuity in relation to the westerly down plunge setting of the high grade mineralised chutes.
Holes BP04-48, 50A, 52, and 55A were drilled to explore the overall depth extent of mineralisation on sections between 49850E and 49950E. All holes successfully passed through the targeted structure with intercepts of barren mafic dyke however, the results suggest that these holes pass under the keel of the overall westerly plunging higher grade zone of mineralisation.
The quantitative impact all these intersections will have on the Company’s resource inventory will not be known until these data have been incorporated in our next resource estimation.
Disseminated intrusive hosted mineralisation Holes BP04-55A and BP04-61 returned significant widths of +0.5% disseminated “UB2” dunite hosted mineralisation on sections 49950 and 49850 respectively. UB2 is the main serpentinised-dunite ultramafic unit containing virtually all the disseminated cumulate mineralization in the Ban Phuc deposit area and is volumetrically significant, constituting the majority of the Project’s resource inventory.
drilling programme was designed to confirm the lateral and
vertical continuity of the lower grade disseminated
mineralisation within the limits of the proposed open-pit
outline. The Company is actively compiling and interpreting
the results received and reported to date. The quantitative
impact of these results on the Company’s resource inventory
will not be known until these data have been incorporated in
our resource estimation, which is currently in progress
