- Hole EL-17-14 assays are high-grade, but drilled down the guts of the Discovery Zone
- Drilling still restricted to a 50m wide section, so 3D orientation of massive sulfide zones are hard to determine accurately.
- However, the drilling to date indicates that the massive sulfide bodies are quite small, but most ore open in several directions suggesting potential to add, albeit limited, tonnages.
Pro-trick for Garibaldi - if you are going to put a table in your press release, don't include a sub-interval that is lower grade, it just shows that you are smearing a very high grade zone over the thickest interval possible.
It is also obvious that this intercept is not close to true widths as suggested below the table, but it shows that Garibaldi thought that the Discovery Zone was parallel to the upper sulfide zone intersected by holes EL-17-04 and 09 and dipping approximately to the NW.
|this is their own interpretation from all of the data|
|10.63m is almost 16.75 meters?|
I've brought the data from hole EL-17-14 into Leapfrog and created a new model (link), I've also done some officially bad mineralized material calculations (TM) to get an idea of the size and potential at Nickel Mountain, to see how GGI can justify a ~CND320m market cap.
- Search distance = 50 m,
- Specific Gravity - I've used an increasing value based on grade, using densities from Sudbury as a base (Note - SGs at the Eagle deposit average 4.44 t/m3)
- >0.5% Ni = 3 t/m3
- >1% Ni = 3.5 t/m3
- >2% Ni = 4 t/m3
- There is no specific orientation on mineralization - as all drilling to date is restricted to 50m wide plane.

Why? There are only 14 holes drilled at Nickel Mountain, no resources, and the massive sulfides appear to be narrow, and inconsistent. Before you hurl abuse at me, just take a step back and ask yourself - what does GGI have to warrant such a high valuation?
I also can't see the upside potential, and I don't like that GGI have been very poor at releasing quality data for the project (you could think there is a reason for this). We still have no plan maps, no geophysical sections, no presentations etc. This isn't something you would expect from professionals running a professional company.
Simply put - Nickel Mountain, Es Mundus Excrementi!
Boring Geology Bit
I've also included some scenes showing my interpretation of the various sulfide zones and their orientations that I can determine from the limited data available. I've split it into 4 separate zones, as I was intrigued by this statement.
Here are the various massive sulfide zones, I've decided to label them, as Garibaldi can't.
Using the data provided, I've created a series of estimated trends for each zone.
To create these trends I lined up the various massive sulfide/high-grade zones in 3D. It was fortunate that Garibaldi don't label these zones on their cross section or in the drill intercept tables.
I apologize to any non-technical readers, the following section is going to be full of geo-wank. I've included some features on the sections through each zone:
- Colors - the Zn grade shells on the section line
- Black line = 25m distance contour from each drill-hole
- Grey line = 50m distance contour
The distance contours show me where drilling has and hasn't occurred and is useful to identify areas that have and have not been drilled.
This is the zone that Garibaldi have been getting erections over, discovered by hole 09, but only recognized 5 holes later.
This zone appears to be almost horizontal, intersected by holes EL-17-02, 04, 09 and 14, but only holes 09 and 14 hit significant sulfides and mineralization.
We can see that hole 09 and 14 are just 20m apart, and the entire zone is only 60m wide, and closed off to the NW by hole EL-17-02 and to the SE by hole EL-17-04. However, it is undrilled to the NE and SW. For me it will be interesting to see if holes 10-13 explore this zone.
Upper Discovery Zone
This zone was defined by holes EL-17-04 and 09. It dips, relatively steeply to the west and is quite narrow (2-5m).
Drill-hole EL-17-02 has closed off this zone to the northwest. Hole EL-17-14, 100m to the east, and EL-17-01 ~50m to the west didn't hit anything, again suggesting this zone is quite small, but with expansion potential.
This zone has been well drilled, it sits above the Historic Zone and appears to be steeply dipping to the SE.
So this zone is closed off to the south (left) with the drilling intercepting narrow >1% Ni zones. However, it is open to the North (right), with hole EL-17-08 intersecting ~6m of massive sulfide mineralization, so again, there is potential to expand this zone with additional drilling.
This is where exploration occurred in the 1960s. It has been well drilled by Garibaldi. To date 6 holes have drilled through this zone, but only 2, EL-17-03 and 07, have returned decent grades. It is closed off to the west by holes EL-17-05 and 06 that were unmineralized. To the north by hole EL-17-08 (unmineralized), and to the west by hole EL-17-01 that cut disseminated mineralization.
However, there is minor potential for this zone to continue to the NE, but the drilling by Garibaldi show that it is very small
So, all I can see is that the sulfides are small, have very variable thicknesses and grades over very short distances, but each zone is open in 1 or more directions. It will be interesting to see where holes 10-13 are located (I'm surprised that they were not able to release the assays from these holes as they were all drilled before hole 14 - could there be a reason - i.e. they are shite), if they are in the same Section, then, for me it just means that even Garibaldi knows that they are small and focusing on this small zone as it is the only area with evidence for massive sulfide mineralization.
