Fraser Range Gold Project
Key Facts
- Revision of (bottom of hole) geological logging and assay data from Fraser Range drilling (March 2007) was undertaken in November 2007.
- The purpose of the drilling was to test a geophysical (gravity ± aeromagnetic) high in the northern drill area, and attempting to gain more information about the bedrock geochemistry over calcrete anomalies and interpreted structural lineaments in the southern drill area.
- Most drill holes yielded weathered to near-fresh I-type granite, usually below shallow saprolite and younger palaeochannel muds and fluvial sediments.
No visible alteration or mineralization was observed in these intersections, but after plotting assay data on a plan of the 
drillingarea it became apparent that there were areas of geochemical anomalism whichwere deemed worthy of follow up drilling.
These areas included a broadly anomalous area of Zn covering holes along the eastern portion of the program (occasionally accompanied by weak Cu and/or Ni anomalism), as well as isolated patchy Cu anomalism in other parts of the drilled area.
One drill hole (FRAC 044) returned reasonable (bottom of hole) anomalism in Au (3m @ 18ppb), Ag (3m @ 0.35ppm), W (3m @ 83ppm) and Zn (3m @ 116ppm with 4m @ 1614ppm above this intersection). This hole also returned weaker Cu and Ni anomalism. The position of DDHAC44 on plan shows it to be within the broader Zn anomaly, and again the geology is within I-type granite which also hosts high levels of magnetic susceptibility (probably due to enriched magnetite content – yet to be established whether magnetite enrichment is an alteration feature).
Also of interest were bottom-of-hole geology intersections from a couple of holes in the central/northwest portion of the drilled area. These holes revealed an increased amount of iron oxide both as an overprint (staining? or alteration?) on bedrock granites (DDHAC10), 
and as a discrete younger layer of chemically precipitated botryoidal hematite ± Mn-oxides (DDHAC16). To the north of these holes was DDHAC13, which showed bottom-of-hole immature arkosic sandstone, suggesting that there is a lithological change from granites to the east (?fault separated; ?unconformity).
