Blue Spec East
A focus of Northwest’s exploration along the Blue Spec Shear is the Blue Spec East target. This target is located less than 400m to the east of the Blue Spec deposit and could be developed as an extension of the Blue Spec deposit from existing underground access.
Northwest has completed detailed structural mapping and compiled a number of innovative geological datasets over the Blue Spec East area as part of the development of Northwest’s predictive targeting model for gold mineralization along the Blue Spec Shear. Significant alteration zones identified by structural mapping in the Blue Spec East area strongly correlated with results from other complimentary datasets. This correlation, together with sophisticated down-hole vectoring techniques, enabled Northwest to successfully target the new shoot position.
A drilling programme was tagerted at Blue Spec East and completed in May 2007. The programme comprised 11 RC drill holes for 1,900m and a single diamond hole to gain structural orientations to assist interpretation of the RC drilling results. Significant intersections included:
- 4m at 4.5 g/t Au from 23m (down hole)
- 10m at 2.3g/t Au from 93m (down hole)
- 18m at 4.2g/t Au from 121m (down hole)
- 6m at 2.7g/t Au from 148m (down hole)
The results of the programme in combination with down-hole structural orientation data have indicated that mineralisation at Blue Spec East dips steeply towards the north and is influenced by the location of a secondary splay fault. The results suggest that this secondary mineralised structure may play a role in controlling the location and plunge orientation of higher-grade mineralisation at Blue Spec East.
At present, drilling intersections within the higher grade zone at Blue Spec East are interpreted to range between 2-5m in true width. Further drilling on the western extent of the identified higher grade mineralisation will be required to further quantify the average true width.
Drilling indicates that the higher grade zone at Blue Spec East lies to the west of the current drilling coverage. Further drilling planned for next quarter will utilise this additional information to more accurately target the location of the potential high-grade shoots.
Importantly, this shoot position is located less than 400m to the east of the Blue Spec deposit and could be developed as an extension of the Blue Spec deposit from existing underground access. Northwest believes further testing of the prospect is warranted as any nearby resource potential which can be developed in conjunction with the Blue Spec deposit will contribute strongly to the Blue Spec project’s economics.
