ARIZONA GOLD REPORTS DRILLING RESULTS AND EXPLORATION PROGRAM UPDATE
Arizona Gold Corp. has provided a drilling and exploration program update at its 100-per-cent-owned Copperstone gold project located in Arizona, United States.
Martin Kostuik, president of Arizona Gold, stated: "We are very pleased to announce the initial results of the completed reverse circulation (RC) drilling program at surface. The surface RC drilling was largely focused on establishing continuity of the Footwall and Copperstone zone mineralization. We are again using the opportunity to continue with the 2018 discovery of the new Footwall zone. Drilling results to date clearly demonstrate the Footwall and Copperstone zones remain open and indicate further expansion of gold mineralized zones along strike and dip with future drilling. Using the same target identification methodologies as for our prior programs, we expected to achieve similar results and, so far, we have."
Mr. Kostuik further stated: "In December we started our underground core drilling and have added a second drill rig with assays currently pending. The underground core drilling is designed to expand resources by drilling for strike and downdip extensions including some portion of infill of previously drilled gold mineral domains, following up on what was a very successful 5,000-metre 2019 drilling program."
Drilling program highlights include:
- 9.1 metres at 6.32 grams per tonne gold, including 3.0 m at 13.52 g/t Au -- AZG-20S-22;
- 6.1 m at 4.86 g/t Au, including 1.5 m at 13.40 g/t Au -- AZG-20S-21;
- 3.0 m at 6.98 g/t Au, including 1.5 m at 12.90 g/t Au -- AZG-20S-04;
- 7.6 m at 4.98 g/t Au, including 3.0 m at 10.54 g/t Au -- AZG-20S-05;
- 4.6 m at 3.56 g/t Au, including 3.0 m at 4.27 g/t Au -- AZG-20S-12;
- 3.0 m at 6.72 g/t Au, including 1.5 m at 12.40 g/t Au -- AZG-20S-17;
- Second underground core drill rig mobilized and drilling ahead of schedule.
2020 drilling program
The surface RC drilling was recently completed, having drilled a total of 5,050 metres, and ranging from 200 to 400 m in depth. Two drill rigs were employed. The program was a continuation of the successful 2017 drilling program performed by the company. Highlights of results from the company's 2017 program that are mentioned in this release are as follows:
- 3.0 m at 3.9 g/t Au, including 1.5 m at 5.1 g/t -- KER-17S-11;
15.2 m at 4.6 g/t Au, including 4.6 m at 13.2 g/t Au -- KER-17S-13;
- 9.3 m at 3.6 g/t, including 4.3 m at 6.8 g/t -- KER-17S-17;
- 7.6 m at 31.2 g/t Au, including 3.0 m at 74.9 g/t Au -- KER-17S-21.
The drilling results confirm continuity of gold mineralization in the Footwall and Copperstone zones intersecting gold mineralization at expected gold grades and higher widths where anticipated while remaining open along strike and dip.
The following provides additional information for each of the drill holes reported above:
AZG-20S-02 is an angle hole collared in the southern portion of the pit east wall, designed primarily to test the strike continuity of gold mineralization within the B zone of the Copperstone zone and test possible parallel Footwall zone extensions 150 m below. The hole extended the strike continuity, at its modelled depth location from the Copperstone zone ALW4 mineralized domain, by 30 m to the southeast. The hole, from 256 to 259 m, intercepted 3.0 m at 2.29 g/t Au, including 1.5 m at 3.53 g/t Au. Anomalous gold grades were intercepted deeper in the hole, which may indicate additional gold mineralization at depth. The hole successfully demonstrates better continuity between the A and B zones than previously known; the area is underdrilled.
AZG-20S-04 is an angle hole collared in the Southwestern portion of the pit, drilled southwesterly to test the continuity of multiple mineralized domains in the Footwall zone. At 82.3 to 85.3 m, previously unmodelled gold mineralization was intercepted returning 3.0 m at 6.98 g/t Au; including 1.5 m at 12.90 g/t Au. This intercept indicates 3.0 m of true thickness and 5.0 m of effective mining width. Further, this high-grade intercept may prove to expand gold mineralization up to a high-grade historic hole located about 47 m to the southwest. Other modelled domains were intersected higher in the hole, which successfully established strike continuity of gold mineralization.
AZG-20S-05 is an angle hole collared in the southwestern portion of the pit, successfully tested the continuity of multiple mineralized domains in the Footwall zone. At 21.3 to 29.0 m, an intercept of 7.6 m at 4.98 g/t was obtained, including 3.0 m at 10.54 g/t; this intercept was about 6.0 m away from strong mineralization in KER-17S-21, which intersected 1.5 m at 12.40 g/t Au. From 64 to 68.4 metres, 2.31 g/t Au was intersected, including 1.5 m at 4.90 g/t Au; the intercept is about 22.9 m updip from a KER-17S-21 intercept. The Footwall zone FW05 domain was intercepted with numerous anomalous intervals about 30 m updip from KER-17S-21. The Footwall zone FW02 domain was intersected about 37.5 m updip from KER-17S-21, with anomalous intercepts. Cut-off grades, or better, near the top of hole successfully indicate a potential new gold domain in the Footwall zone.
AZG-20S-06 is an angle hole collared in the southwestern portion of the pit, successfully tested the updip extension of multiple mineralized domains in the Footwall zone. From 25.9 to 27.4 m, a 1.5 m intercept of 6.93 g/t Au was obtained, located about 15.2 m away from KER-17S-21. The Footwall zone FW05 domain was successfully intersected about 3.0 m updip from KER-17S-21, with 4.6 m at 3.04 g/t Au, including 1.5 m at 4.13 g/t Au. The Footwall zone FW02 domain was successfully intersected about 36.6 m updip from KER-17S-21, with 4.6 m at 2.84 g/t Au. Cut-off grades, or better, near the top of hole successfully indicate a potential new gold domain in the Footwall zone.
AZG-20S-12 is a vertical hole drilled in the southwest area of the pit, targeting Footwall zone mineralization. From 135.6 to 140.2 m a 4.6 m intercept with a grade of 3.56 g/t Au, including at 135.6 to 138.7 m with 4.27 g/t Au. The indicated true thickness is 3.8 m and the effective mining width is 6.7 m. The intercept is an effective strike extension of approximately 30 m to the southeast, extending the edge of this inferred area of the Footwall zone marked by historic drill hole KER-17S-13.
AZG-20S-14 is an angle hole drilled southwesterly, successfully testing the continuity of gold mineralization in the Footwall zone in an updip direction. From 89.9 to 117.3 m, four each 1.5 m intercepts were drilled, with grades ranging from 1.10 to 2.60 g/t Au. These results demonstrate updip continuity from KER-17S-11 of about 107 m. At 233.2 to 234.7 m, a 1.5 m intercept of 7.50 g/t Au was intersected and it displayed an indicated true thickness of 1.3 m and an effective mining width of 2.2 m. Also, at 242.3 to 243.8 m, a 1.5 m intercept of 3.24 g/t Au was returned. Each intercept effectively resulted in an updip extension of gold mineralization, from historic KER-17S-11, of approximately 61 m.
AZG-20S-17 is a vertical hole drilled in the southwest area of the pit, confirming Footwall zone gold mineralization continuity. From 32 to 35.1 m, a three m intercept at 6.72 g/t Au was intersected, including a return, from 33.5 to 35.1 m, of 12.4 g/t Au. This is a 107 m updip expansion from historic KER-17S-17 and 15.2 m updip and along strike from historic hole CS-210 which returned five m of 1.10 g/t Au. At 105.2 to 106.7 m, a 1.5 m intercept of 2.76 g/t Au was drilled. This is an approximately 61 m updip extension of mineralized shear from historic KER-17S-17. At 178.3 to 179.8 m, a 1.5 m intercept of 1.03 g/t Au was found, which is an approximately 30 m updip extension of gold mineralization from historic KER-17S-17.
AZG-20S-21 was drilled from the southern portion of the East wall of the pit, angled to the east. It was drilled for the purpose of confirming the orebody in this B zone area of the Copperstone zone. Within 153.9 to 160 m, a 6.1 m intercept was drilled at 4.86 g/t Au, including from 157 to 158.5 m, returning 1.5 m at 13.40 g/t Au. The indicated true thickness is 4.5 m and the effective mining width is 7.9 m.
AZG-20S-22 was drilled from the East wall of the pit, angled to the west. It was drilled for the purpose of confirming the orebody in this A zone area of the Copperstone zone. The AUP1 domain of the Copperstone zone was successfully intercepted as modelled, returning 9.1 metres at 6.32 g/t Au from 85.3 to 94.5 m, including from 91.4 to 94.5 m returning 3.0 m at 13.52 g/t Au. The thickness of the gold mineralization is greater than surrounding holes and potentially expands the AUP1 domain of the Copperstone zone along strike to the northwest. The indicated true thickness is 8.4 m and the effective mining width is 14.7 m.

* Grades herein are reported as uncapped values.
** Estimated distance between the foot wall and hangingwall of the mineralized
zone measured perpendicularly to the edges.
*** Effective mining width is defined as the distance between the foot wall and
hangingwall of the mineralized zone measured horizontally and matches the planned
mining method. The mining method used to calculate reserves will extract ore by
drift mining along strike in a defined ore stope. The effective mining width is
the width that miners will be working within.
The underground drilling was initiated in November with one drill. Beginning in January, a second drill was mobilized to the Copperstone underground workings in order to accelerate the current program. Assay results are pending.
The primary focus of the current drilling program is further extending the known boundaries and increasing the current resource in both the Copperstone zone and the underlying and parallel Footwall zone. The Footwall zone is located about 150 m to the southwest of the Copperstone zone, which historically produced, via open-pit mining and a whole ore leach gold processing plant, over 500,000 ounces of gold at an average grade of three g/t Au.
