i-80 Gold Expands High-Grade Mineralization in the Blackjack Zone at Ruby Hill

 

 

 

 

 

10.1 % Zinc, 0.3 g/t Gold, 37.0 g/t Silver & 0.6 % Lead over 116.3 meters
16.1 % Zinc, 0.5 g/t Gold, 12.4 g/t Silver & 0.1 % Lead over 16.1 meters

 

i-80 GOLD CORP. (TSX: IAU) (NYSE: IAUX) is pleased to report continued high-grade poly-metallic results from the ongoing drill program at the Company’s Ruby Hill Property located in Eureka County, Nevada.

 

The current drill program is focused on both defining and expanding high-grade mineralization in multiple target areas including the Blackjack (skarn) and the Hilltop (skarn and polymetallic CRD) Zones, and advancing metallurgical work associated with these deposits. The most recent intercepts in the Blackjack Zone include the first hole drilled from the east side of the Archimedes pit, which intersected significant high-grade mineralization at depth in the southern portion of the deposit where it remains open for expansion. Highlight results from new drilling include:

 

Blackjack Zone

  • iRH23-42
    • 8.3 % Zn, 0.6 % Pb, 50.1 g/t Ag & 0.6 g/t Au over 20.1 m
  • iRH23-42A
    • 10.1 % Zn, 0.6 % Pb, 37.0 g/t Ag & 0.3 g/t Au over 116.3 m
      • Including 16.3 % Zn, 0.5 % Pb, 42.3 g/t Ag & 0.3 g/t Au over 39.7 m
      • And 14.5% Zn, 1.0% Pb, 59.9 g/t Ag & 0.2 g/t Au over 16.3 m
  • iRH23-43B
    • 16.1 % Zn, 0.1 % Pb, 12.4 g/t Ag & 0.5 g/t Au over 16.1 m
    • Also 12.2% Zn, 0.1% Pb, 20.1 g/t Ag & 0.9 g/t Au over 8.6 m

 

“The exceptional results being realized at Ruby Hill have attracted significant interest with high-grade polymetallic mineralization being defined in multiple target areas,” stated Tyler Hill, Chief Geologist of i-80. “Recent drilling has returned some of the highest-grade mineralization to-date in the Blackjack Zone as we continue to step-out to the south and at depth. Additionally, following the construction of the new drill stations better suited to intersect the East Hilltop Zones, substantial CRD and Skarn mineralization is being defined highlighting the potential to expand mineralization in these recently discovered zones.”

 

These new intercepts are complemented by other recent drilling at Blackjack including iRH23-41 that intersected both CRD and skarn mineralized zones that assayed 15.6 % Zn, 8.7 % Pb, 420.4 g/t Ag & 0.6 g/t Au over 40.4 m (CRD) and 10.7 % Zn, 0.4 % Pb, 0.2 g/t Au & 37.0 g/t Ag over 47.9 m (skarn). Skarn mineralization in the Blackjack Zone occurs proximal to the contact of the Graveyard Flats intrusive, and identical geological setting at the East Hilltop Skarn Zone located approximately three hundred metres (300 m) to the south. Future drilling will test this large area as no previous drilling has been completed between these two high-grade horizons (see Figure 1).

 

Drilling is also being completed in the Upper and East Hilltop Zones situated along the Hilltop fault structure where multiple zones of mineralization have now been defined over a strike length of approximately 750 metres including the Upper, Lower and East Hilltop Zones (see Figure 1). As part of the ongoing drilling campaign, several holes are currently being drilled to advance metallurgical knowledge related to the polymetallic mineralization at Ruby Hill. This work is being funded by a third-party company that has recently entered into exclusivity with i-80 to acquire a minority joint venture interest in the Ruby Hill Property.

The ongoing drill program is also testing the FAD deposit that is located approximately two kilometres to the south of Ruby Hill where earlier drilling completed by Paycore returned intercepts of up to 8.0 g/t Au, 79.0 g/t Ag, 10.0 % Zn & 1.0 % Pb over 27.4 m in hole PC22-10, and 7.1 g/t Au, 376.0 g/t Ag, 6.3 % Zn & 10.3 % Pb over 14.8 m in hole PC22‑08.

 

The Company has submitted for approval its plan to develop an underground mine at Ruby Hill with mineralization accessed via a ramp from the Archimedes open pit. The target is to commence construction in 2024 to provide underground platforms for definition drilling and mining operations.

 

Multiple types of mineralization have been identified in the Hilltop Corridor including skarn (Blackjack), CRD (Hilltop/historic mines), distal disseminated Au-Ag mineralization (Mineral Point) and locally Carlin-type gold.

 

The Eureka (Ruby Hill) Mining District has a history of high-grade polymetallic CRD production that began in the 1860’s and spanned a period of more than one hundred years. Historic mined grades rank amongst the highest for any CRD district in the world. Since the 1960’s, the CRD potential of the Eureka District has been largely overlooked in favour of exploration for Carlin-type gold deposits and the Company considers the opportunity to be substantial. The Ruby Hill Property is one of the Company’s primary assets and is host to the core processing infrastructure within the Eureka District of the Battle Mountain-Eureka Trend including an idle leach plant, an active heap leach facility, and is host to multiple gold, gold-silver and polymetallic (base metal) deposits.

QAQC Procedures

 

All samples were submitted to American Assay Laboratories (AAL) of Sparks, NV, which is an ISO 9001 and 17025 certified and accredited laboratory, independent of the Company. Samples submitted through AAL and are run through standard prep methods and analyzed using FA-PB30-ICP (Au; 30g fire assay) and IO-4AB32 (35 element suite; 0.5g 4-acid ICP-OES+MS). Select high-grade gold samples were also completed with metallic screen fire assays using G-FASFAu11. AAL undertakes their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration. i-80 Gold Corp’s QA/QC program includes regular insertion of CRM standards, duplicates, and blanks into the sample stream with a stringent review of all results.
