RENO,
Nev., April 25, 2023 /PRNewswire/ - i-80 GOLD
CORP. (TSX: IAU) (NYSE: IAUX) ("i-80", or the
"Company") is pleased to announce that drilling has
discovered new lenses of high-grade poly-metallic carbonate
replacement deposit type (CRD) and skarn mineralization along the
Hilltop fault structure and continues to expand mineralization in
the Hilltop Zones and at the Company's 100%-owned Ruby Hill
Property ("Ruby Hill" or "the Property") located in
Eureka County, Nevada.
Highlight results from initial 2023 drilling at Ruby Hill
include:
- iRH23-09:
-
- 3.4 g/t Au, 11.1 g/t Ag, & 6.7 % Zn & over
18.3 m (Lower Hilltop Zone)
- 9.9 g/t Au over 5.8 m (Ruby
Deeps Zone)
- 9.2 % Zn & 0.1 % Cu over 3.1
m (Geddes Zone Discovery)
- iRH23-10:
-
- 0.6 g/t Au, 165.6 g/t Ag, 6.7 % Zn & 6.6 % Pb over
13.4 m (East Hilltop CRD
Discovery)
-
- including 0.5 g/t Au, 226.1 g/t Ag, 9.7 % Zn & 10.0 % Pb
over 8.4 m
- 3.2 g/t Au, 366.0 g/t Ag, 19.8 % Zn & 10.2 % Pb over
0.9 m
- 0.3 g/t Au, 63.0 g/t Ag, 13.9 % Zn, and 1.6 % Pb over
2.3 m
- iRH22-69:
-
- 0.3 g/t Au, 25.3 g/t Ag, 5.8 % Zn & 0.3 % Pb over
10.7 m (Blackjack Skarn
Zone)
- 0.5 g/t Au, 13.5 g/t Ag, & 8.2 % Zn, over 5.0 m
- 11.6 g/t Au over 13.1 m
(Lowerjack Zone)

4.7 m (Blackjack Skarn Zone)
- 449.0 g/t Ag, 7.0 % Zn & 16.4 % Pb over 1.4 m (Blackjack Skarn Zone)
Exploration drilling in 2022 discovered multiple zones of
high-grade CRD and skarn mineralization along the newly identified
Hilltop fault structure located on the south side of the Archimedes
open pit with intercepts up to 515.3 g/t Ag, 28.9 % Pb, 10.5 % Zn
& 0.9 g/t Au over 28.3
m. The 2023 drill program is focused on delineating the
known zones and testing for the potential of additional
mineralization along the Hilltop fault. Early drilling has
been successful in expanding mineralization in the Hilltop horizon
over a strike length of 750 metres including the discovery of new
lenses of high-grade mineralization in the East Hilltop area and
also along strike to the west.
"Our 2023 drill program has picked up where we left off in 2022,
expanding high-grade mineralization in several zones and resulting
in multiple new discoveries.", stated Tyler
Hill, Chief Geologist of i-80 Gold. "These results
confirm a substantial mineralized system that remains open for
expansion making us optimistic of further discoveries as several of
our priority targets remain to be tested."
CRD massive and semi-massive sulphide mineralization has been
discovered in the East Hilltop target area between the Upper
Hilltop Zone and the East Hilltop Skarn Zone (See Figures 1 & 2). The first hole to
intersect this new zone of CRD mineralization, iRH23-10, returned
multiple high-grade intercepts including 0.5 g/t Au, 226.1 g/t Ag,
9.7 % Zn and 10.0 % Pb over 8.4 m
& 3.2 g/t Au, 366.0 g/t Ag, 19.8 % Zn and 10.2 % Pb over
0.9 m with full results provided in
Table 1. Definition and expansion drilling is underway and the
horizon remains open along strike and at depth.
Step-out drilling along the western extension of the Hilltop
fault structure has resulted in the discovery of high-grade CRD and
high-grade carlin-type gold mineralization with hole iRH22-09
intersecting multiple zones including 3.4 g/t Au, 11.0 g/t Ag, 6.8
% Zn over 18.3 m (Hilltop West), 9.9
g/t Au over 5.8 m (Ruby Deeps
extension) and 9.2 % Zn over 3.0 m
(Geddes CRD discovery). The Hilltop West intercept consists of a
broad zone of CRD breccia proximal to the Holly fault and located
approximately 250 m west of the Lower
Hilltop Zone. High-grade gold mineralization occurs immediately
below the breccia mineralization and is believed to represent the
southern extension of the Ruby Deeps gold deposit located
approximately 200 metres to the north. Ongoing drilling is now
focused on testing the area between these two zones. The Geddes CRD
discovery consists of high-grade massive sulphide mineralization
located in the footwall of the Holly fault structure in area of no
previous drilling. The Geddes CRD zone represents a new mineralized
stratigraphic unit in the Geddes limestone that has seen only a
handful of drillholes across the property.
Drilling is also focused on defining and expanding
mineralization in the Upper, Lower and East Hilltop Zones.
Since the initial discovery of the Hilltop Zone in mid-2022, the
Company has gained significant understanding of the controlling
features of the CRD system with the identification of the northwest
trending Hilltop fault structure. High-grade mineralization
occurs in both the hanging wall (north) and footwall (south) sides
of the fault and is thickest where subsidiary north-south and
northeast-southwest structures intersect the Hilltop fault (see
Figure 1). Skarn mineralization develops along the Hilltop fault to
the east towards the Graveyard Flats intrusive stock with new
results confirming the potential for significant expansion.
Impressive mineralization continues to be intersected in recent
holes with assays pending.
Drilling is also being completed in the Blackjack Deposit to
better define mineralization for an initial resource estimate that
is expected to be released following the 2023 program. The
Blackjack deposit is located immediately below the Archimedes pit
and was discovered by Homestake and Barrick prior to the
acquisition of the Property by i-80. High-grade skarn
mineralization occurs proximal to the Graveyard Flats intrusive
stock and is underlain by high-grade Carlin-type gold mineralization, the Lowerjack
Zone. The ongoing initial drill program is confirming
mineralization in both horizons with initial highlight results from
the first two holes drill to test this part of the Property
assaying up to 7.1 % Zn, 3.5 % Pb, 3.7 g/t Au and 116.7 g/t Ag in
the Blackjack Zone and up to 11.6 g/t Au over 13.1 m in the Lowerjack Zone. Neither zone is
included in the current mineral inventory at Ruby Hill.
The Company has five drills active at Ruby Hill, completing a
large-scale surface drill program for both deposit delineation and
exploration purposes. Further definition of the Upper Hilltop Zone
will be completed once new drill pads are permitted and can be
established. In the interim period, the East Hilltop target
area is one of the primary focal areas with significant
mineralization being defined in an area with little to no previous
drilling.

The 2023 program will also test several priority geophysical
targets identified on the Property. The ongoing infill and
step-out drill program will aide in the advancement of the
Company's plan to develop an underground mine at Ruby Hill,
accessed via ramp from the Archimedes open pit. Following the 2023
program, an updated mineral resource estimate is planned that will
include initial estimates for the polymetallic deposits followed by
economic studies.
It is expected that refractory gold mineralization from the
planned underground operation at Ruby Hill will be trucked to the
Company's Lone Tree facility, once
operational, and plans are being advanced for the potential
processing of polymetallic mineralization on-site at the existing
Ruby Hill plant. The Company is currently completing additional
work regarding a possible retrofit of the existing Ruby Hill
processing plant to a floatation plant that would recover base and
precious metals. The existing permitted infrastructure at Ruby Hill
is expected to reduce not only the permitting timeline normally
associated with mine construction, but also the expected capital
cost associated with mine development.
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 a currently idle processing plant
and an active heap leach facility. The Property is host to multiple
gold, gold-silver and poly-metallic (base metal) deposits
collectively representing one of the largest development-stage
projects in Nevada.

QAQC Procedures
All samples were submitted to either American Assay Laboratories
(AAL) or ALS Minerals (ALS) both of Sparks, NV, which are ISO 9001 and 17025
certified and accredited laboratories, independent of the Company.
Samples submitted through AAL and ALS are run through standard prep
methods and analysed using Au-AA23 (ALS) or FA-PB30-ICP (AAL) (Au;
30g fire assay for both) and ME-ICP61a (35 element suite; 0.4g 4
acid/ICP-AES) for ALS and IO-4AB32 (35 element suite; 0.5g 4-acid
ICP-OES+MS) for AAL. Both AAL and ALS also 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.
