Despite encountering drilling difficulties that resulted in the abandonment of two holes at their Rockford project in the Fraser Range, Legend Mining says it gained a valuable insight into the geology in the area.
Legend Managing Director Mark Wilson said “When the geology from these holes is considered along with the magnetic, gravity and EM datasets the setting is consistent with the possible presence of Ni-Cu mineralisation. The rig has now moved to Conductor 4 and new techniques are planned to overcome difficulties experienced in the first two holes. We will drill new holes at Conductors D1 and D2 later in this programme.”
The company says the drill holes intersected several dense rock units including olivine gabbro, pyroxene-rich granulite and garnet-rich granulite which are consistent with the observed discrete gravity feature.
Legend kicked off a 5 hole RC drilling campaign on February 22nd aimed at testing five strong to moderate conductors identified by moving loop electromagnetic surveying at Areas D and F.
Detailed geophysical modelling of the conductors indicated down hole target depths to conductor source ranging between 150-325m.
These drill holes are the first deep RC holes in the re-known Fraser Range region which is also home to the massive Nova-Bollinger Nickel find.
Legend says it is able to confirm the presence of “Fraser Zone” rocks within the Rockford Project and the information obtained from the drilling to date is seen as positive and highlights the prospectively of Area D for Nickel and Copper mineralisation.
Changes to the drilling technique have now been implemented to assist with the penetration and casing of “running” sand in the transported cover sequence and the program is now expected to be completed within three weeks.
