Alexander River is looking to be a lot larger than first thought with these new mineralised shoots.
8 metre thick trench results @ 7.5grams/tonne gold
8.5metre thick drilling @ 11g/t Au in AXDDH012
"The unmined Loftus McKay shoot has been identified by surface sampling and recent drilling. The shoot plunges moderately to the NE, is around
200m high, extends for 300m down plunge and is open at depth. The shoot width pinches and swells but to date ranges from around 2-15m thick.
"Surface trenches and drillhole intersections shown in Figure 1 indicate that the McVicar mineralised shoot is up to 8m thick (8m @ 7.5g/t Au in Trench G, 8.5m @ 11g/t Au in AXDDH012). Mapping by Max Gage in 1942 shows that the McVicar reef stoped between Levels 5 and 6 and a new west dipping reef was found on L6. Macraes Mining Company Limited (now OceanGold Limited) drilled three holes from L6 in the early 1990’s. The westernmost hole (A6-3) intesected a 5.4m quartz reef 25m below L6 that averaged 5.3g/t Au."
"The Loftus McKay shoot outcrops from above Pad 12 to Mullocky Creek (Pad 45) as shown on Figure 1. Sampling across the outcrop by Siren (15m @ 7.4g/t Au and 8m @ 4.1g/t Au) (Figure 2) and partial outcrops (2.5m @ 6.4g/t Au and 5m @ 4.0g/t Au) and drillhole intersections indicate that the Loftus McKay shoot plunges around 50o to the NNE (Figure 1) and is around 200m high compared to 75m for the McVicar shoot. The west
dipping reef intersected in the McVicar mine and A6-3 indicates that a second shoot, the McVicar West shoot, may lie approximately 200m below the Loftus McKay shoot (Figure 1)"
If you compare the latest schematic diagram to the previous one at the bottom, you can clearly see significant additional high grade gold mineralisation in these two new mineralisation gold shoots. Loftus-McKay Shoot and McVicar Mine/Bull Shoot. (Beneath the trench or dotted line).
The scale of the image has been doubled from 0-250metres in the old diagram to 0-500metres. This helps to understand the shear size of these additional high grade quartz reefs and lodes.
@metaljaune, do you think with this latest announcement an open pit larger scale gold mine is more probable than underground?
