Santana reported (ASX Announcement
The CIT prospect lies in the north-west sector of the NW-SE trending Rise and Shine Shear zone (RSSZ) and associated hanging wall shear (HWS) which dip at a shallow angle to the NE. The HWS also referred to as 'lode schist' occupies the uppermost part of TZ4 biotite schist and is separated from the overlying lower metamorphic grade unmineralized TZ3 chlorite schist by the
Arsenic is used as a gold pathfinder element in regional surveys and in drill chip and core logging to provide a real-time guide to gold levels to assist in drillhole planning and site location / relocation. Historically arsenic levels >1,000 ppm As, indicate gold ore grades.
Composited intervals of >1,000 ppm As samples with 2 metre internal dilution (at zero grade) were intersected in all new CIT RC drillholes with significant intercepts up to 28 metres in HWS / lode schist immediately below the TGF. The northernmost RC drillhole, MRC070, is collared >200 metres NNE of existing resources.
RC drillholes MRC064, MRC065, MRC066, MRC069 and MRC070 appear to delineate a NNE trending area extending from existing resources where higher gold grades could be expected as indicated from higher levels and broader thicknesses of pXRF arsenic analyses. RC drillholes MRC067 and MRC068 appear to be on the fringe of the NNE trending area.
Dip sections transversely cross the NNE trend of higher pXRF arsenic, with highest grades characteristically occurring immediately below the TGF in all drillholes.
Diamond core drilling, with MDD001 at the CIT Deposit was the first to be conducted within the project area and oriented core provides important structural data for geological logging and resource modelling. Preliminary pXRF orientation arsenic analyses are being conducted to determine optimum pXRF analytical intervals to compliment geological interpretations.
Quartz-arsenopyrite breccia veinlets are also evident in MDD001 at 102 metres, below the intensely sheared, altered and stockwork HWS lode schist zone extending mineralisation from 61 to 102 metres below collar.
A total of 423 samples of TZ4 schist and the immediate overlying TGF and TZ3 schist have been despatched for gold fire assaying (FA505) with results expected in mid-January. The DD rig is currently onsite at MDD002 at the
