We see the share price surge after Cordoba released assay data from a spectacular drill-hole at San Matias (link).
|I've annotated so it is simpler to understand|
The initial resource was a good start (link), I was surprised that they didn't wait until they had a larger resources (say >100Mt), but I assume that they felt it was important to release an initial resource and build on that.
What I have done is take the data from the recently released DH data to see how much more mineralization they have potentially drilled at Alacran. Here is the official resource:
Since the initial resource calculation, Cordoba have released the data from an additional 14 holes (link). Unfortunately, Cordoba don't give any decent plan maps to accompany the press releases, the ones they do release as missing grid coordinates and they don't label all of the holes which means I have to guess which hole is which (I'll let you make various innuendos).
UPDATE: I've had some feedback, and the reason that Cordoba don't release the drill-hole coordinates isn't just to piss me off, it is to prevent the informal/artisanal/illegal (select as appropriate) miners from knowing exactly where Cordoba have been drilling and going to those places and start to mine. In many countries in S. America dealing with informal miners can be very difficult and I can understand CDB taking measures to prevent this.
|Some holes are labelled, but the other holes listed in the PR are the black colored ones. Nice and easy!!|
You can see that we have gaps in mineralization, these are unmineralized areas and are fairly common in porphyry systems. Typically they are caused by later, unmineralized intrusives (dykes - Panoro's Cotabambas project is a good example of this) cutting through the mineralization. Here they appear be caused by maybe less reactive or more competent units within the siltstones. It isn't clear.
Here are my officially bad (tm) resource calculations. For this I've used the following parameters:
- Specific Gravity = 2.8
- A trend on mineralization that follows the sediments
- 200m search (i.e. Leapfrog connects intervals that are within 200m from one another)
|red line = trend for grade shells|
Here are my estimations with all the recent drilling:
So we see he have had a nearly 20Mt increase in resources and we haven't seen a drop off in grade, which is nice.
In the leapfrog model I've also included a few historic holes drilled at Montiel East.
|Nice thick copper zones, starting at surface!|
I see on Inkacola that people are trying to ratfvck you on the mining stock message boards.ReplyDelete
This can mean only one thing.
You're doing good work.
Keep it up!
AT Round Up, HPX / Cordoba had cross sections up on the foam core board. Likely they will have some again out at PDAC to put the drilling and mineralization in more context. If I recall the conversation correctly, the narrow high grade intercept released that day was not enountered in the undercutting drill hole. As we know, that depends on the orientation of the narrow vein (potentilly tough to determine with a single drill hole) and orientation of the cross section. Hoping for more from the property than just Alacran.ReplyDelete
At the moment it is a single hit, and I can see this going 1 of 2 ways.
1. CDB commit a small amount of drilling to define a small, high grade resources
2. focus on the bigger picture and continue drilling the porphyry mineralization and report high-grade holes as and when they hit them.
I will push for (2) as that is their focus, high-grade hits are nice, but don't contribute much to a large, open pit deposit.
That is really good and informative post. You have shared the whole concept really well. Thanks for sharing it with usReplyDelete
Seems to be going to where it started, share wise. Too bad.ReplyDelete
so, one of my better deals!Delete
I just started buying, did i miss something?ReplyDelete
Sorry for taking some time to reply. I think the market were not impressed with the way the deposit was drilled by HPX. Basically they drilled the crap out of it and didn't really go beyond the known mineralization. This was a bit unadventurous especially as they had a very high-grade gold hit that they could have follow-up on.Delete
