AntaKori update

A quick Anta Kori update from the latest round of drilling (link) from a couple of weeks ago. The results were good, with holes AK10 and 13 hitting thick zones of copper and gold mineralization.

Holes 11 and 12 were relatively poor, but if we look at the drilling in a bit more detail, we can see that there is a geological reason for this.

Let us go through each hole.


This hits lots of mineralization, all nicely skarn mineralization and appear to be sitting above/over an interpreted porphyry. It is strange that historic holes SDH-033 didn't hit anything, but where it entered the limestone we can see that it appears to have intersected some post mineral intrusive and southern legacy were focusing on the high-sulfidation mineralization.


This hole was a bit crap, but really it was unlucky, it managed to drill a load of young, post mineral (?) volcanics that have stoped out (removed) the skarn and HS mineralization The narrow intervals could be fragments of skarn (xenoliths) in the volcanics.


On the surface, another poor hole, but it didn't intersect the limestone that hosted the great zone intersected by hole AK-18-009 and terminated in the upper volcanics hosting the high-sulfidation mineralization. But if you look at this section, we have holes AK14 and 17 and these should get some juicy hits


Almost the twin of hole AK10. Best grades were in the HS zone near surface, and in the underlying limestone the hole hit a well mineralized (>0.5% CuEq) skarn zone.

You can get the LF viewer file from here (link)

On the plan map and sections we have are shown the location, direction and inclination for some more holes, here are my predictions:

  • AK14 - this is a steeper hole drilled from the same platform as hole 12. I'm guessing that it will hit ~300m @ >1% CuEq starting from ~240m depth.
  • AK15 - drilled 100m east from hole AK10. My guess is that it'll get 160m @ >1.0% Cu Eq from 150m depth (Skarn mineralization), before drilling into the underlying fine grained sediemnts which will contain ~0.5% CuEq from 320-400m depth.
  • AK16 - almost vertical hole being drilled from the same collar as AK13. I'm guessing that it will return similar grades to hole AK2 (330m @ 0.66% CuEq)
  • AK17 - also drilled from the AK12 pad, it should hit a nice interval of >1% CuEq from 150 to 520m
  • AK18 - Hole drilled way out to the east exploring the near-surface high-grade (HS) hits in holes SRC-007, SDH-044. This hole could be an interesting one to watch, as if they find decent skarn mineralization over east, then there is potential for decent resource expansion.
  • AK19 - main target appears to be the near-surface HS mineralization. The majority of this hole appears not to be on the Regulus concession
  • AK20 - HS exploration hole to the north of the deposit, exploring the high-grade HS mineralization intersected in holes SDH-005 and 010. It appears that the majority of the hole will be outside the Regulus concessions.
So, it should be an interesting couple of months..


  1. Hey AG. Don't take this the wrong way but you always seem to fail to mention the Co (or trading symbol) involved. This is Regulus, REG.v for those interested. Here's the latest news. Appears some uber low grade and doesn't that make you cranky usually?

  2. Ace, AG linked the news release in his first sentence AND discusses it in his post, what are you on about?! 327.35 m of 1.31% CuEq is indeed UBER low.... wtf dude, maybe this deposit is a bit too complex for you

    1. My point, like your head, is about slapping the name of the co and symbol up front so dopes don't have to wonder and then go look for it. 'AntaKori' alone doesn't help.

      Cu at $ 2.83 or somesuch means your hand picked uber hole and (CuEq ... pfft) isn't QUITE as super duper as wicked dopey pumpers would have public types think.

    2. Just to follow up here the CuEq comes from Ag (circuit required) and the Au which will likely ONLY be economic in a 'heap leach' senario. (.40 gms/t.) I didn't bother with what price these terds applied because both Au and Cu are on a slippery slope.

  3. Cross section (Figure 5) shows porphyry and limestone (hence related skarn mineralization) eroded before deposition of Miocene volcanic rocks. Therefore, there must have been a significant time interval between porphyry and later mineralization overprinting Miocene volcanic rocks. If so, Cu-Au-As event in volcanic rocks (source presumably not yet identified) is unrelated to earlier porphyry.

    1. yes, essentially there has been continuous volcanic/intrusive activity from 40Ma to recent times. The contact between the Limestones and miocene volcanics looks like an unconformity.

  4. Really like to hear if these are still "uber low grades" Ace.

  5. So overall do the posters here like this stock, or think it is not so good? I was concerned about the Arsenic levels, and whether I was duped into believing this stock can become something. With respect to what we know so far is this looking like an economic deposit?

    1. You have 2 styles of mineralization
      1. high-sulphidation Au-Cu with As mineralization that they are mining next door
      2. Cu Skarn minealization in the limestones

      Essentially this project will get bought by Tantahuatay and incorporated into their operations as they are mining right up to the property boundary. The question will be when, and for how much. This will depend on how much resources Regulus define.

  6. I love your sarcasm especially when companies keep drilling the same zone over and over. Waiting for an update on Regulus if ever when they release more results, and Westhaven if they find some new zones.
