RC37 vs RC26
This pair of drill holes are very interesting. As shown below, they are very close to the same location. RC26 is a few metres to the east and a metre to the north. Except for precise calculations, they are basically in the same spot.


As per the intercept chart below, RC26 had an intercept of 3 metres from 100 to 103. Perhaps more importantly, across 132-140m the hole hit low grade lithium bearing Mafic. While Mafic in drill holes is usually at the top &/or bottom of the hole, in this instance it appears to be a side of the pegmatite mafic reading. TG6 figured out that it was probably caused by a very nearby pegmatite and in RCD37 they managed to find that other pegmatite.


Where RC26 intercepted only 100-103m, its twin RCD37 hit 97.7-99.25m and a robust grade pegmatite from 119.4m to 127m @ 1.37%. This 2nd pegmatite was possibly 5-10m higher than expected but for drilling of Pegmatite purposes, it was in the correct space. RCD37 also hit mixed Quartz / Mafic readings with low grade lithium across 116.2-119.4m and 127m-132m. If TG6 has hit right on the edge of where a pegmatite starts, this 7m intercept could expand to 10m+ relatively quickly in the same way RC26 transitioned from nothing to the intercept in RCD37. Where TG6 reports peg/Mafic then Mafic/Peg, did TG6 manage to get some core with pegmatite on one side and Mafic on the other? If they did it may not look pretty to a layperson but I'm sure the geologists would be excited. The lower 0.95% and 0.58% grades would be because they are right on the very edge of the pegmatite.


I had a play around with some trig calculations and they indicated that the point where RC37 intersected the pegmatite at 97.7m was about 8m south of where RC26 hit at 100m and just slightly higher. This is shown in the WowVeryJosh graphic below where right is north. As RCD37 and RC26 are at the same surface spot, only RC26 is showing as a title. The purple disc is the 97.7-99.3m intercept and the blue disc is 119.4-127m. The height differential between the purple and yellow disks points towards a gentle pegmatite slope down to the north (consistent with other modelling). With no 2nd intercept, the charting software isn't plotting any pegmatite because its got no idea about size shape or slope directions. TG6 is yet to report several nearby drill holes including RC38 and RC45. They will help clarify how big this pegmatite might be.

This 7m intercept has the right sort of height slope to be the thinner intercept 400m south at RCD0043 which at this stage is only shown graphically. If it does extend north, RC36 is likely to have hit something and TG6 has more pegmatites in the near surface zone. How wide, that's far from clear at present.
