1/ .@BellCopperBCU has a great exploration story at Kabba. See my thoughts on the #copper play in Arizona here:…
2/ The roots of the porphyry system are exposed at surface approximately 8 kilometers west of their exploration area and the top of the system was split from the roots by a fault.
3/ The deposit of interest is concentrated in the top of the system and it was either moved downwards and preserved under the valley, or moved up and eroded away.
4/ It's a simple story, but the devil is in the details. Thankfully, Bell Copper has a technical team that understands the details and is taking a scientific approach to exploration.
5/ That is particularly important for copper exploration in Arizona since the State has produced such a large amount of copper historically (10% of all copper ever mined in the history of the world?!) that most prospects have been picked over many times.
6/ Kabba itself has been drilled since the 1950s, but past programs drilled down into roots of the system and found they were not mineralized. That is to be expected based on current models of porphyries, but was surely a troubling surprise for the exploration geologists of...
7/ ...the past. Who would have thought that rock they were looking for had been displaced approximately 8 kilometers to east and buried under a mountain of gravel?
8/ The valleys in Arizona are typically very smooth at surface, but Tim told me that they can have as much relief at bedrock as is seen in the nearby mountains! What's more, the gravel cover can be relatively thin.
9/ Kabba had enough features of interest to keep people working on it for decades, but recent developments in the understanding of porphyries and local geology has put Bell Copper in a good position to finally find the upper part of this system.
10/ Watch for cross sections from the most recent round of drilling if they hit significant copper to see just how deep we are talking about here.
11/ I asked Tim why he has stuck with this project for so long – why does he think this porphyry is mineralized?
12/ He said, "Any time I lose faith, I get back on the footwall and look at those veins. The volume of fluid required to produce that much chemical change in rock is impressive and I'm gonna find this thing if it's the last thing I do…" $BCU.V

1/ Shoutout #ESSCO Earth Science Services Corp. and the Stargate II (SGII) system.
2/ The SGII team always has some interesting things to say on CEO.CA -- see for more.
3/ The SGII system is used to help guide drilling activity. See this map for an example:… Map that only a geologist could love...

1/ The story of #CoralGold $CLH.V sale of the Robertson project to @BarrickGold is very interesting. CEO David Wolfin describes the details in 2016 interview with Jay Taylor that I found very helpful:
2/ The key consideration for Barrick's business development committee is the IRR against a baseline gold price. When negotiating the sale of the Robertson, Barrick needed the project to meet a 15% IRR at $1,250 gold.
3/ In the 2016 interview with Jay Taylor, Mr. Wolfin describes how he negotiated for the royalty to be set as high as possible at $1,250 gold and then to increase with each $200/ounce increase in the gold price up to a maximum 2.25% NSR.

1/ Coral Gold (TSX.V:CLH) has been active in Nevada for over 30 years, developing a meaningful relationship with Barrick Gold (TSX:ABX) that has already led to one significant asset sale. Coral Gold negotiated a nice royalty with a sliding scale for the NSR and annual payments...
2/ ...due if not the Robertson is not in production by 2025! Coral has several other assets nearby that could have similar success, but CEO Mr. David Wolfin has already described the royalty on the Robertson as a potential company maker.
3/ Bell Copper (TSXV:BCU) has a deal with Kennecott Exploration under Rio Tinto (LSE: RIO, ASX:RIO) for a porphyry project in Arizona that is close to becoming a copper porphyry. Bell Copper is still the majority owner for the project, but their partner is earning in quickly.

1/ Goldboro! Part 1 of #NewtonInterviews The Unknown Geologist on the geological model for this exciting gold project in Nova Scotia, Canada owned by @Anaconda_Mining:…
2/ Quotes from the Unknown Geologist to follow... "I know the Boston Richardson model very well."
3/ I remember reviewing a diagram of the Boston Richardson belt that shows the historic mining, and it highlights the top and bottom of an ore shoot on both limbs.

1/ Find out what The Unknown Geologist has to say about the @Anaconda_Mining Goldboro Project in Nova Scotia, Canada:…
2/ Unknown Geologist:I remember Dustin asking me to highlight some key points about Goldboro. Like how many ounces of gold do we think Goldboro will host? I said to him…you've got 850,000 now, when all is said and done, Goldboro will have at least 2,000,000 ounces.
3/ I said, look at it this way, the deepest hole ever drilled in Goldboro was about 400 meters deep. Dolliver Mountain, which once hosted the largest stamp mill in the province, is 1.5 kilometers out to the west of the main ramp area.

1/ In this interview with #BobMoriarty, Bob tells a story about the famous Nugget Pond Mine in Nova Scotia that strikes a chord with his excellent 2016 book "Nobody Knows Anything: Investing Basics Learn to Ignore the Experts, the Gurus and other Fools"…
2/ Bob Moriarty:Let me talk about the dumbest mining company in Canadian history. You may be familiar with it. Do you know where the Nugget Pond mine is?
3/ The Unknown Geo:Yes.
