‘Gold-rich zone‘ – ‘Open-ended mineralization‘ – ‘Areas previously untested by historic drilling‘… when a junior explorer trots out this kind of wordage in the intro of a communique, pay attention to the details that follow.
When the crew behind such phrasing is top shelf—a crew not prone to puffery or hyperbole—pay close attention to the details that follow.
An example—a recent headline out of the Arizona Metals camp:
“Arizona Metals Corp. (AMC.V, AZMCF.OTCQX) is pleased to announce the results of an additional ten drill holes at the recently discovered gold-rich zone of open-ended mineralization at the Kay Mine, in areas previously untested by historic drilling or exploration.”
You may have also noticed assay values in the text of the headline—this is another positive lead. In this case, closer attention is definitely warranted.
The grades and widths presented in the above headline are impressive. Note the copper and gold values.
Twenty-four meters grading 5.0% Cu, 0.6 g/t Au, 1.0% Zn, and 23 g/t Ag is rich rock—coppers recent price trajectory offers some context regarding just how rich.
Arizona Metals’ flagship project—the Kay Mine Project—is located in a world-class mining-friendly jurisdiction currently ranked #2 by the esteemed Fraser Institute (Arizona currently leads the U.S. in copper production).
Investment Attractiveness Index (published Q1, 2021)
The extraordinary mineral endowment of this district gave rise to no less than 60 underground Cu-Au-Zn mines during its century-long run.
~4 billion pounds of copper was produced, all within a 150-kilometer radius of the Company’s flagship.
These deposits were formed via a series of volcanic hydrothermal events along seafloor beds when tidal H2O enveloped the region. These are what’s known as Volcanic Massive Sulphide (VMS) deposits.
Everything You Need to Know about VMS
High-quality VMS deposits are on the radar of every resource-hungry producer looking to bulk up its project pipeline (pipelines made lean by the brutal bear market of the past decade).
Why are these deposits so highly prized? Though they vary in scale—from < one million tons all the way to up to 100 million—these polymetallic orebodies often hold huge concentrations of metals due to their rich nature.
The right VMS orebody can be a company-maker.
And as you may already know, especially if you’ve been following this rapidly evolving exploration/development play for any length of time, VMS deposits rarely occur in isolation. They almost always occur in clusters—where there’s one deposit (or lens), there are often others.
The grandsire of this prolific VMS district was United Verde—30 million tons (Mt) at 5% copper PLUS an extension deposit that produced 3.5Mt at 10.2% Cu, 1.3 g/t Au, and 58 g/t Ag (fabulously rich rock y’all).
The Kay Mine Project carries a (historical) resource courtesy of Exxon Minerals back in the day (the early 1980s).
Exxon reported a “proven and probable reserve of 6.4 million short tons grading 2.2% copper, 2.8 g/t gold, 3.03% zinc, and 55 g/t silver.” ***
To blow the doors open on this project—to bring these historic pounds-in-the-ground into 43-101 compliance (and then some)—the Company is pushing Kay aggressively along the curve and is currently in the midst of a 75,000-meter Phase-2 drill program—a campaign that was accelerated back in June with the addition of a third drill rig.
Back to the October 12th headline…
This recently discovered gold-rich zone of open-ended mineralization (in areas previously untested by historic drilling), generated the following highlights:

The (geological) models are a-changin
This last batch of results—wide, high-grade intervals—carry the potential to add significant tonnage outside of the historic resource block where Exxon Minerals defined two discrete mineralized zones—North and South—separated by 100 meters on strike.
Connecting the dots—demonstrating good (vertical) continuity—is the key to establishing positive economics in any underground mining scenario.
This Phase-2 campaign by Arizona Metals indicates that these two zones—North and South—are LINKED… NOT distinct as once thought.
This new model augments Kay’s tonnage potential.
This next map is a good one (nice one fellas). It depicts the two extremes generated via the business end of the drill bit—the shallowest and the deepest holes drilled to date.
Assays are pending for KM-21-46 (200 meters depth) and KM-21-42A (850 meters depth).
The Structural Mapping Campaign
Surface mapping is a valuable tool in teeing up drill targets at Kay.
As an Isoclinal Folded Deposit, the folded hinges of the deposit are the thickest sections of mineralization and represent the most compelling drill targets—targets that often demonstrate superior grades and widths.
Quinton Hennigh offers a good example of Kay’s Isoclinal folded geology comparing the underlying structure to that of a taffy pull (Hennigh talks Kay’s unique geology beginning at 26:40 via the video linked below)…
Crescat Gets Activist on Gold & Silver #32 – Arizona Metals Corp ($AMC.V)
This next pic demonstrates this folding characteristic at Kay, at surface. Note the ‘folding’ going on along the upper section of this outcropping rock…
In September 2021, the Company initiated a detailed surface structural mapping campaign to update and supplement structural mapping completed in 2019.
The results from this mapping program will be combined with core logging data to refine drill targets at pads 4, 5, and 6 (map below). These pads will test for mineralized extensions roughly 500 meters to the north and 300 meters south of the main mineralized body.
Other high-priority drill targets on the property—the Central and Western targets (C1 and C2 – W1 and W2 on the map below)—are located roughly 0.5 kilometers and 1.3 kilometers to the west of the Kay deposit. Surface mapping will also refine these targets for a proper probe with the drill bit early next year.
In a recent chat with CEO Pais, I learned that the Central targets can be drilled from pad 3 (permits to drill these highly prospective targets should arrive soon).
These regional targets represent a compelling speculative dynamic—an element of intrigue if you will—to this rapidly evolving (VMS) story. Both will see their subsurface layers probed during this Phase-2 campaign.
To fully appreciate this regional potential, note the scale on the map below.
Marc Pais, CEO:
“The ten drill holes released today continue to demonstrate the richness and size potential of the Kay Mine system. Virtually all holes drilled to date at Kay have intersected semi-massive to massive sulphide mineralization, with assays pending on ten more holes, and three holes currently underway.
In Phase 2 the deposit has been drilled to 775 m below surface (in Hole 27) along a strike length of 300 m and drilling continues to expand Kay mineralization in all directions with assays pending on a number of holes up to 850 m below surface. Holes 40 and 41 were drilled to test above and below the high-grade intervals encountered in Holes 24, 26, and 28. Both Holes 40 and 41 demonstrate exceptional vertical continuity of thickness and grade in this portion of the deposit. Drilling is currently underway with three drill rigs to test for further extensions of high-grade mineralization, both laterally and targeting depths below 900 m.
Our geological model, especially the modeled orientation of mineralized zones, is evolving rapidly as we drill, and is confirming a deposit considerably larger than reported historically. Our drill program is evolving to reflect these changes, and we are currently drill testing a number of new targets both at depth and near surface.”
The Company is currently drilling with three rigs—three drill crews, 20 drillers, two onsite geos supervising activity—drilling twenty-four hours a day, seven days a week.
I suspect that by now, the Company is nearing the halfway point of this 75,000-meter campaign.
Three holes are being shipped off to the lab every month.
Lab turnaround is currently nine to ten weeks.
Final thought
The plot underpinning the Arizona Metals story is evolving rapidly. In a recent Guru offering, I speculated the following…
The narrative now becomes, how big can this thing get? Or, more precisely… could this turn into another United Verde? If the Company continues to encounter broad intervals of high-grade mineralization outside the historic resource block, the answer is an emphatic “YES”.
That remains my opinion. I suspect Arizona Metals will fall prey to a resource-hungry predator, one that will swoop in and take this project out at a fat premium to current price levels.
We stand to watch.
