TORONTO, April 05, 2023--( BUSINESS WIRE)--Arizona Metals Corp. (TSX:AMC, OTCQX:AZMCF) (the "Company" or "Arizona Metals") is pleased to announce that step-out exploration drilling has intersected a potential new zone of copper-gold-zinc VMS mineralization located 600 m north and along strike of the Central Target EM anomaly. Hole KM-22-95 intersected 2.7 m grading 0.5% CuEq. at a vertical depth of approximately 320 m. Clasts of massive sulphide mineralization have been observed in this interval, which can be indicative of proximity to primary massive sulphide mineralization. Follow up drilling is planned to test for extensions of the mineralization encountered in this hole.

Figure 1. Plan view of Kay project exploration targets, drill intercepts, and drill infrastructure. Hole KM-22-95, located 600 m north of the Central Target EM anomaly, intersected 2.7 m grading 0.5% CuEq. See Tables 1-3 for additional details. The true width of mineralization in this area is yet to be determined. See Table 1 for constituent elements, grades, metals prices and recovery assumptions used for AuEq g/t and CuEq % calculations. Analyzed metal equivalent calculations are reported for illustrative purposes only.
Extensional drilling located at the northern edge of the Kay Mine Deposit intersected 8.8 m of 4.8% CuEq in hole KM-23-97. This hole extended mineralization by 100 m north of hole KM-22-71A and confirmed the vertical continuity of high-grade mineralization in the 160 m between holes KM-20-11 and KM-21-19.
The Company is also pleased to report six additional holes from the Kay Mine Deposit, including both infill and extensional holes.
Drilling at the Western Target commenced in February 2023. The first hole is this area, KM-23-104, is currently underway and has been drilled to approximately 650 m west of pad W1 and to a vertical depth of 700 m below surface. Upon completion of this hole, the Company will undertake a downhole electromagnetic survey to test for extensions of conductors previously observed in both helicopter and ground-loop electromagnetic testing.
Arizona Metals is fully-funded (with $53 million in cash at Dec 31, 2022) to complete the remaining 3,800 meters planned for the Phase 2 program at Kay Mine Deposit (budgeted at $1.6 million) as well as an additional 76,000 meters in the Phase 3 program (budgeted at $32 million), which will be used to test the numerous parallel targets heading west of the Kay Mine Deposit, as well as possible northern and southern extensions.
Marc Pais, CEO, commented "The drill results reported today continue to demonstrate the expansion potential of the Kay Mine Deposit itself, and that it has the potential to be part of a much larger mineralized system.
In January, we announced that VMS mineralization had been intersected approximately 300 metres north of the Kay Mine Deposit. At the Central Target, located 500 metres west of the Kay Mine Deposit, all the holes that have intersected the electromagnetic anomaly have encountered anomalous zinc and graphite mineralization. We believe this style of mineralization is consistent with mineralization distal to a primary volcanic hydrothermal vent zone. Support for this model has come from hole KM-23-105, which intersected 2.7 m at 0.5% CuEq, 600 metres north of the Central EM anomaly and 400 metres west of the Kay Mine Deposit (see Fig 2). The presence of this mineralization demonstrates increasing proximity to a hydrothermal vent zone. We view the 600 metres between the Central Target EM anomaly and hole KM-23-105 as highly prospective for massive sulphide mineralization and are planning a number of drill holes to test this area.
We are also pleased to report that drilling of the first hole at the Western Target is currently underway and we are now targeting the second hole in this area. Downhole electromagnetic surveying of the first hole is expected to commence shortly".
Drilling Details—Kay Mine Deposit
Recent drilling at the Kay Mine Deposit has focused mainly on step-out holes to probe the extent of mineralization.
Hole KM-22-97
8.8 m @ 4.8% CuEq and 1.5 m @ 1.3% CuEq
Along the north edge about mid-way down the deposit, this hole extended mineralization ~100 m north of hole KM-22-71A and confirmed the vertical continuity of high-grade mineralization in the 160 m between holes KM-20-11 and KM-21-19.
Hole KM-22-98
Three intervals, including 4.6 m @ 0.8% CuEq and 4.3 m @ 0.9% CuEq
Drilled from pad 1 into the central upper part of the deposit, extending mineralization about 65 m upward into the gap between the upper North and upper South zones.
Hole KM-22-99
9.6 m @ 0.6% CuEq and 3.0 m @ 0.9% CuEq
A step-out hole along the north edge of the deposit. Together with hole KM-22-97, extends mineralization about 160 m north of hole KM-22-71A in the upper middle portion of the deposit.
Hole KM-22-63B
1.5 m @ 0.5% Cu Eq
Deep in the deposit, north of KM-22-63D
Hole KM-22-94
Three intercepts: 17.7 m @ 0.7% CuEq, 3.2 m @ 1.1% CuEq, and 1.3 m @ 0.8% CuEq.
This is a step-out hole deep in the deposit along the north edge, 33 m north of hole KM-21-27 and 55 m north of hole KM-22-57B.
Hole KM-22-94A
Several intercepts, including 10.4 m @ 1.2% CuEq, and 3.4 m @ 2.1% CuEq.
This hole wedged about 60 m below KM-22-94 and proved continuity between that hole and hole KM-21-51B.
Kay North Extension
Hole KM-22-80
Two intervals: 5.6 m @ 0.9% CuEq, 3.0 m @ 0.5% CuEq
Drilled from pad 6 to the east, north of the main Kay Mine Deposit. These intercepts are deep within the footwall of the deposit and are the easternmost intercepts. This suggests either potential for other deeper horizons or possible complex folding.
Hole KM-22-91
1.8 m @ 1.1% CuEq
Drilled from pad 6 to the east. Extends mineralization about 150 m north of KM-22-87, which is located along the northern edge of drilled mineralization.
Central Target
Hole KM-22-95
2.7 m @ 0.5% CuEq from 432.8 m downhole. This is a mineralized intercept in a new area: 600 m along strike north from the north end of the Central EM anomaly, and 500 m west of the other drill intercepts in the pad 4 area.
Drilled northwest from pad 4, to test a strong soil anomaly
The mineralization is relatively Zn-rich (0.22% Cu, 0.12 g/t Au, 0.61% Zn) and is clearly distal. It lies about 10 m to 20 m downhole of and stratigraphically below the mafic-felsic contact on the east limb of the Central anticline.
This interval shows mineralization along the prospective horizon far from any other known mineralization.
Kay Mine Project Phase 2 Drill Program Update
With the assayed holes released today, the Company has completed a total of 79,600 meters at the Kay Mine Project since inception of drilling. The Company is fully-funded to complete the remaining 3,800 meters planned for the Phase 2 program with the priority focus areas for upcoming drilling (shown in Figure 1 above) as well as an additional 76,000 meters currently planned for the upcoming Phase 3 program.

The true width of mineralization is estimated to be 50% to 99% of reported core width, with an average of 76%. (2) Assumptions used in USD for the copper and gold metal equivalent calculations were metal prices of $4.63/lb Copper, $1937/oz Gold, $25/oz Silver, $1.78/lb Zinc, and $1.02/lb Pb. Assumed metal recoveries (rec.), based on a preliminary review of historic data by SRK and ProcessIQ1, were 93% for copper, 92% for zinc, 90% for lead, 72% silver, and 70% for gold. The following equation was used to calculate copper equivalence: CuEq = Copper (%) (93% rec.) + (Gold (g/t) x 0.61)(72% rec.) + (Silver (g/t) x 0.0079)(72% rec.) + (Zinc (%) x 0.3844)(93% rec.) +(Lead (%) x 0.2203)(93% rec.). The following equation was used to calculate gold equivalence: AuEq = Gold (g/t)(72% rec.) + (Copper (%) x 1.638)(93% rec.) + (Silver (g/t) x 0.01291)(72% rec.) + (Zinc (%) x 0.6299)(93% rec.) +(Lead (%) x 0.3609)(93% rec.). Analyzed metal equivalent calculations are reported for illustrative purposes only. The metal chosen for reporting on an equivalent basis is the one that contributes the most dollar value after accounting for assumed recoveries.
