Red Ribbon Shear
In June 2006, Northwest announced the discovery of the Red Ribbon Shear. The shear trends parallel to the Blue Spec Shear, lying approximately 1km north and has now been mapped over a strike length of approximately 18kms within the Blue Spec Shear Project area.
Northwest believes that the Red Ribbon Shear has the same potential as the Blue Spec Shear to host multiple high-grade, near surface, gold deposits. This discovery has effectively doubled the strike extent within the Blue Spec Shear gold project area to over 30kms.
Structural mapping, rock chip and soil sampling completed over the new Red Ribbon Shear has confirmed that the new shear has the same key characteristics as the Blue Spec Shear. These similarities include:
- Generation of structure - Structural characterisation of both the Blue Spec Shear and Red Ribbon Shear indicates that both shears are of similar age and have accommodated significant movement during the main mineralising event.
- Alteration signature - A distinct alteration assemblage comprising limonite-sericite-carbonate that is associated with the Blue Spec Shear has also been recognised along the strike extent of the Red Ribbon Shear.
- Metal association - The Red Ribbon Shear records similar pathfinder element associations as those recorded along the Blue Spec Shear. Sampling of visible stibnite-bearing veins at surface from the Red Ribbon Shear has confirmed a gold-antimony metal association similar to the high-grade Blue Spec Shear.
