Arizona Gold Drills 22.2 g/t Gold
TORONTO, April 07, 2021 (GLOBE NEWSWIRE) — Arizona Gold Corp. (TSX: AZG, OTCQB: AGAUF) (“Arizona Gold” or the “Company”) provides additional underground drilling results and drilling program update at its 100% owned Copperstone gold project located in Arizona, United States.
Giulio Bonifacio, President & CEO of Arizona Gold, stated: “We are pleased to announce additional results from the underground core drilling program which continues to show continuity and extension in mineralized domains over good mining widths. Additionally, we see further indications of previously unknown mineralization below the previously defined mineralized domain CUVND3, which is indicated in Figure 2. We are now moving forward with in-fill definition drilling of planned stopes, which will provide information for final stope design planning, as shown in Figure 1. Additionally, upon completion of the current phase of drilling, the Company will provide an updated resources estimate which will also include drilling results from 5,000 meters of successful drilling in 2019.”
Drilling Highlights Include
Drill Hole AZG-21-13-12
• 1.5 m at 22.07 g/t gold (“Au”), and 1.2 m at 11.73 g/t Au
Drill Hole AZG 21-13A-18
• 4.7 m at 2.34 g/t Au; including 0.9 m at 5.33 g/t Au
Drill Hole AZG-20S-23
• 15.2 m at 3.27 g/t Au; including 6.1 m at 6.02 g/t Au
The underground exploration core hole drilling is ongoing and has focused on the D zone of the Copperstone shear zone. Continuity and extension of mineralized domains were realized in many holes. Figure 1 shows the new drilling in plan view. Figures 2, and 3 show the drilling in cross section, and Table 1 summarizes drill hole assay results. Drill hole intervals of prior drill programs mentioned in this release are as follows:
Drill Hole A98-5
• 170.1 – 171.6; 1.5m at 7.03 g/t Au (CUVND2)
• 173.1 – 179.4; 6.2m at 21.59 g/t Au (CUVND3)
Drill Hole CSD-9
• 149.2 – 154.8; 5.6m at 8.33 g/t Au (CUVND2)
• 157.0 – 160.8; 3.8m at 0.91 g/t Au (CUVND3)
Drill Hole KER-17U-16
• 15.2 – 16.3; 1.1m at 20.70 g/t Au (CUVND3)
Drill Hole CS-367
• 155.4 – 160.0; 4.6m at 8.16 g/t Au (B Zone)
Continued Indication of New Domain Below CUVND3
Drill hole AZG-21-13A-18 intersected 0.8 m at 1.14 g/t Au, indicating a possible new domain 18m below the CUVND3 domain. This adds a fourth hole showing the possible new domain. Drill hole AZG-20S-16 intersected 1.5 m at 2.69 g/t Au, indicating the potential for a new domain below the CUVN domain. Historic drilling in this area has not shown strong Au mineralization, so there is potential for resource expansion with additional drilling. The following provides additional information for each of the drill holes reported above (Also See Figures 1 through 3):
AZG-21-10-17 is an up angle core hole drilled northwesterly and collared in station 10 in the D Zone. It intersected 4.8 m at 3.32 g/t Au (including 0.9 m at 7.13 g/t Au and 1.2 m at 5.47 g/t Au), successfully extending the CUVND3 domain about 27.4 m up dip. The hole also intersected 0.8 m at 14.80 g/t Au, which is a possible extension of the CUVND domain about 15.2 m up dip from its current modelled extent.
AZG-21-13-12 is an up angle core hole drilled northeasterly and collared in station 13 in the D Zone. It intersected 1.5 m at 22.07 g/t Au, successfully targeting the CUVND3 domain about 29 m up dip of drill hole A98-5, about 12.2 m down dip of drill hole CSD-9 and about 15.2 m along strike to the northwest of drill hole KER-17U-16. It also intersected 1.2 m at 11.73 g/t, successfully targeting the CUVND2 domain about 26 m up dip of A98-5, and 15.2 m down dip of CSD-9..
AZG-21-13A-18 is an up angle hole drilled to the west and collared in station 13A in the D zone. It intersected 4.7 m at 2.34 g/t Au (includes 0.9 m at 5.33 g/t Au), about 7.5 m above the CUVND domain, which might be an offset of the domain or a new domain. The hole also intersected 0.8 m at 1.14 g/t Au, indicating a possible new domain 18m below the CUVND3 domain.
AZG-20S-16 is a surface down angle RC hole drilled westerly from the east side of the pit into the C Zone, with a total depth of 305 m. It intersected 9.1 m at 1.98 g/t Au (includes 3.0 m at 3.57 g/t Au), successfully targeting the C Zone mineralization where modelled. It also intersected 1.5 m at 2.69 g/t Au, indicating the potential for a new domain below the CUVN domain, which may be related to the Footwall Zone. Historic drilling in this area has not shown strong Au mineralization, so there is potential for resource expansion with additional drilling.
AZG-20S-23 is a surface down angle RC hole drilled northwesterly from the east side of the pit into the B Zone, with a total depth of 172 m. It targeted and successfully intersected 15.2 m at 3.27 g/t Au (includes 6.1 m at 6.02 g/t Au), also intersecting 1.5 m at 1.24 g/t Au. The intercepts confirm grade and mineralization 6 m down dip from historic drillhole CS-367.
The underground exploration drilling program is nearing completion. The primary focus of the drilling program has been to extend the known mineralized domain boundaries and demonstrate continuity of mineralization in areas where drill hole spacing was greater than average. The Copperstone Mine has 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 about 3 g/t Au.

|(2) Estimated distance between the foot wall and hanging wall of the mineralized zone measured perpendicularly to the edges.|
|(3) Effective Mining Width is defined as the distance between the foot wall and hanging wall 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.|

Quality Assurance and Quality Control Statement
Procedures have been implemented to assure Quality Assurance Quality Control (QAQC) of drill hole assaying being done at an ISO Accredited assay laboratory. Drill hole samples to be assayed are securely stored for shipment, with chain of custody documentation through delivery. Mineralized commercial reference standards or blank standards are inserted approximately every 20th sample in sequence and results are assessed to ascertain acceptable limits for analytical variance. Duplicate samples will also be taken as a further check in lab precision and accuracy. All results will be analyzed for consistency and corrective actions taken, if needed.
About Arizona Gold Corp.
Arizona Gold is an emerging American gold producer advancing the restart of production at its 100-per-cent-owned, fully permitted, past-producing Copperstone mine project, located in mining-friendly Arizona. The Copperstone mine project demonstrates significant upside exploration potential that has yet to be drilled within a 50 square-kilometre (12,258 acres) land package that includes past production of over 500,000 ounces of gold by way of an open-pit operation.
The company’s current focus is on maximizing Copperstone’s potential by defining and expanding current resources and further optimizing the mine’s economics for purposes of the restart of gold production in 2021 as a result of the recent project funding transaction entered into with Star Royalties Ltd.
