GT Gold - more holes in the (North) Saddle

We've had a new PR from GT Gold (link). Some interesting results, but the market didn't like them.

Summary:

Good News

• The >0.5% CuEq mineralization appears to come to surface (hole TTD108)

The Bad News

• High-grade mineralization restricted to a specific zone (the Stock-work zone)
• This zone appears to be discontinuous (i.e. it doesn't seem to join up well between drill-holes), and the best zone is deep

Overall, I don't see, from the data presented, much evidence that the North Saddle zone will grow into something huge. The best mineralization appears to be inconsistent, with the best intercepts at depth.

In More detail....

In my last post I was partially correct about a preferred 'trend' in the mineralization. In fact, on the sections provided in this PR we can see that virtually all of the good mineralization is found in a specific 'unit' - what is labelled as the intense stockwork zone.

I've highlighted on the sections that accompanied the PR.



You can clearly see why hole TTD098 missed. It was drilled parallel to the stockworks just clipped it. Imaging if this hole had been drilled a degree steeper, it would have hit >300m @ >1% CuEq. The market would have liked that.

From the sections I've tried to model this zone in 3D (file here - link).



We can see that the stockwork zone is:

• Narrow (~max thickenss 250m)
• inconsistent (forms separate, probably discrete zones)
• Steeply dipping to the SW

Unfortunately, for me, I can't see how the Stockwork zone is going to get much bigger.

• On section 5620 (the most northwesterly section) the zone is very narrow and runs along the fault.
• On section 5830 (the most southeasterly section), the stockwork zone again is very small and deep
• Only on section 5740 do we get 2 zones
• upper narrow zone (hole TTD106 and 108 - approx 100m wide) that continues to surface
• lower deep zone (TTD093) that starts at 400-450m depth, that is ~200m wide

We have to remember these section are ~160m apart, which makes that stockwork zone quite small.

I'm certain that hole TTD109 will get something great (probably 400m @ >0.75 g/t Au and 0.5% Cu starting from 700m depth), but so what. All it will be doing is confirming what was hit in hole TTD093, it won't tell us anything new, we already know that they have some moderate mineralization at depth. To be special and make this project, hole 109 need to get something special.

GT Gold Corp - Back in the Saddle

That teaches me for not paying close attention to the market, a spectacular rise in GTT.V share price after some juicy porphyry hits at Saddle North.

Obviously, you can remind me of my terrible comment from my last post (link).

I suck..

So, we'll ignore the drilling at the Saddle deposit, the market doesn't care about these, and focus on the porphyry.

You can get a Leapfrog viewer file here (link) to look at it in 3D-goodness.

At the moment it is early days, we have the data from 3.5 holes (hole TTD062 stopped before hitting the guts of the porphyry), so it is hard to know the full scale of the mineralization (this is me covering my ass), but the IP data may give us a hint.

I'm ignoring the mag data as it doesn't really help us (there is a huge anomaly), but the IP data may give us a potential size of the porphyry system.



and a close up...

It looks like the copper mineralization is found in a 500m long by 200-300m wide zone. From the sections, this zone dips to the SW, and may also dip to the NW (based on the fact that the Western n changeability high associated with the pyrite halo is more subdued, suggesting that it is at greater depth).

I'm also intrigued by the fact that in none of the literature do GT Gold mention any bornite, just chalcopyrite and pyrite. At another small porphyry deposits in the area we see this:

Bornite in the middle like jam in a donut

The best grades are found in the core, which often a lot of bornite, as we see no mention of this, there is a good chance that they still haven't drilled it. My guess is that it will be found to the west of hole TTD092.

Circle marks the spot..

When I look at the Saddle North Plan map (link), I noticed that a couple of the drill-holes, TTD098 and TTD107, don't appear to be optimally located. They appear to be targeting the pyrite halo and may only hit erratic, low-grade intervals (<0.25% CuEq with narrow zones of ~0.5% CuEq).



However, I'll be very interested to see what hole TTD102 gets, this could hit the bornite core and could get some decent, thick intervals of high-grade (>1% CuEq) mineralization.

I'm also interested in hole TTD106, if this gets grades similar to TTD085 (100+m @ >0.3 g/t Au and >0.3% Cu), this would be very positive as when you look at the sections, you can see that the highest grade mineralization starts at ~400m depth.



Is this potentially too deep?
