I thought it was active seismic that was around needing/having reflectors - you create a shock wave and have an array of sensors to receive the rebounded signal. The passive seismic is more about horizontal shock wave movements and the speed of shock wave took to travel between two points. From this you get velocity readings that can be interpreted as density readings. From the density readings you can interpret what might be pegmatites (~2.7x density) vs some of the other unweathered volcanic's at nearer ~2.9x to 3.0x density or highly weathered rock (~2.0x density). Denser material has faster shock wave travel.

In the ideal situation the seismic work would indicate speed of shock wave movement consistent with the density of pegmatites in locations where pegmatites had been drilled. Both Core and A11 have used ANT to identify larger pegmatite bodies but A11 noted it didn't identify a thinner (<20m peg's) that they knew existed from previous drill work. Both however had pre-existing 50m+ intercepts. While A11 stopped using Fleet space they did soon after using it come up with their dogleg hits including 83m @ 1% from 36m and 69m @ 1.25% from 45m. Hits like that would be a game changer for TG6. TG6's lack of 30-50m intercepts may mean there isn't strong independent validation from existing drilling to the model. When TG6 add the drilling from Burmeister into the model it creates an improvements and Seismic remains consistent with these new constraints but also points towards to new targets in Burmeister. The geologists are happy but its a hard sell for the public. Look we told the model were pegmatites were and found pegmatites in the model!!

The second part of the ideal situation is having the seismic suggest a pegmatite exists in an undrilled area. TG6 then drills that area you gets a pegmatite intersection in the area and depth expected. So lets say TG6 is sitting on a seismic model that suggests a 30-50m or perhaps even bigger pegmatite exists. What does TG6 do:
a) high stakes gamble - release the seismic and state we plan to drill here. If TG6 hit something, great their hero's. If they have a duster, they look like idiots and the market loses some confidence in their modelling/targeting abilities.
b) low stakes gamble - note seismic is being used in selecting drill targets. Drill in an area informed by soils that also has a seismic signature.

The seismic is released along with either drill collar and intercept length information if a pegmatite is hit (testing ASX's wrath as they don't like that) or trying to get assay's back quickly and release as a bundle - first Jaegermeister drilling along with Seismic.

Its looking increasingly as if TG6 is taking the low stakes gamble.
