I'll also need any information of the geology intersected in Tyn13

and Tyn14. Such as dips, location of faults, and any sulphide

intersections.



My current understanding is that the geology is generally striking

N-S and steeply dipping to the west (80 degrees or so). The geometry

of any orebody should be approximately the same, and will lie on the

contact between the western CVC andesite and the eastern Lower

Tyndall Group rhyolites. I will use this as the basis for designing

transmitter loop layouts.



The best way to test the prospective horizon is to utilise several

transmitter loop positions. In order to do this we need some level of

flexibility during the survey to alter transmitter looop locations

dependent on results. I will be planning to use 400 x 400m

transmitter loops for the DHEM surveys at Basin Lake. A question is:

Do we have a 400m radius around each of the two drillholes in which

we could position a transmitter wire without the need for cutting

lines? If so then all should go well.



The current plan is for two Tx loops per hole. These have the

following corner cor-ords:



TYN013

Tx1	380750mE, 5354600mN Top left

	381250mE, 5354600mN Top right

	381250mE, 5354200mN Bottom right

	380750mE, 5354200mN Bottom left

Tx2	381250mE, 5354600mN Top left

	381650mE, 5354600mN Top right

	381650mE, 5354200mN Bottom right

	381250mE, 5354200mN Bottom left



TYN014

Tx1	380650mE, 5353800mN Top left

	381050mE, 5353800mN Top right

	381050mE, 5353400mN Bottom right

	380650mE, 5353400mN Bottom left

Tx2	381050mE, 5353800mN Top left

	381450mE, 5353800mN Top right

	381450mE, 5353400mN Bottom left

	381050mE, 5353400mN Bottom right



These locations are designed for maximum coupling with the current

mineralisation model, and for logistical ease in the field. If a

conductor is found to be present in the data then extra loop

locations will be utilised.
