Ann: Downhole EM Conductor Identified at Wodger, page-40

Well, this fell off the watchlist. Been busy, er, 'correcting perceptions' over on the Pilbara threads.

I think this is as expected. DHEM anomaly off-hole as expected, low-grade copper as expected (a bit lower than I guessed but same-same), with a couple of metres of good grades around the vein system, as expected.

Epigenetic, as expected.

The comment that this is remobilised from somewhere else, I would agree with. But whether that is close to the massive sulphides or far away, that is the question. This comes down to whether the remobilisation was mechanical or hydrothermal. If it's mechanical (squeezing or smearing) I would say <100m. Which would involve that conductor.

But I don't think it is mechanically remobilised. The vein textures (brittle, angular looking and planar veins) don't look like shearing, and native copper doesn't get remobilised. So it would be hydrothermally remobilised, and there's two thoughts on this. #1, copper won't go far from the source, or #2, it will go far from the source.

I think that won't be known for quite some time, if at all.

Other positives: the un-drilled gap between Wodger and Big Billy. This is begging for a vacuum drilling program to sample the base of hardpan or top of basement, let alone a decent thrashing with AC drilling. The NE trending structures evident in the gravity are definitely interesting, and are substantial lineaments (tiny structures don't tend to show up on gravity).

One of these structures truncates the north of Wodger. Suck a thumb and you would say the plunge of Wodger points down toward this NE structure; there's your target for where the mineralisation would be remobilised from and the structure which might control the epigenetic system.

Overall positive.
