Near-Mine Exploration Success Presents
Opportunity to Extend Mineral Reserves and Mine Life
SSR Mining Inc. (NASDAQ/TSX: SSRM, ASX: SSR) ("SSR Mining" or
the “Company") is pleased to announce results from 48 drill holes
completed at the Puna project (“Puna”) for the period of August,
2022 to December, 2022. Puna includes the Pirquitas and Chinchillas
properties, both located in the Jujuy Province of northern
Argentina (see Figure 1). Chinchillas is an open pit
silver-lead-zinc mine and is the current source of the ore
processed at the Pirquitas processing plant, located approximately
42 kilometers southwest of the Chinchillas property.

The 2022 exploration program focused on resource expansion,
discovery and reconciliation drilling at Chinchillas and was the
first exploration drilling completed at the property since 2016. Of
the 48 holes reported, 27 targeted extensions of the Chinchillas
mineralization to the east, northeast and at depth. Drilling also
intersected mineralization at the Melina zone and at Socavon Del
Diablo, two separate targets located adjacent to existing
Chinchillas infrastructure that host potential to complement the
ore currently mined from the main Chinchillas deposit.
Additionally, two drill holes were completed at the Cortaderas
target on the Pirquitas property.
Drilling highlights from the Chinchillas property include (see
Figures 2 and 3) (see Table 1):
- CHN22-341: 65 meters at 386 g/t Ag (435 g/t AgEq) from
53 meters
- Including: 27 meters at 836 g/t Ag (913 g/t AgEq) from
73 meters
- CHN22-374: 63 meters at 219 g/t Ag (451 g/t AgEq) from
90 meters
- Including: 18 meters at 382 g/t Ag (840 g/t AgEq) from
101 meters
- CHN22-343: 31 meters at 453 g/t Ag (542 g/t AgEq) from
25 meters
- CHN22-347: 30 meters at 422 g/t Ag (479 g/t AgEq) from 2
meters
- Including: 16 meters at 699 g/t Ag (797 g/t AgEq) from 9
meters
Rod Antal, President and CEO of SSR Mining, said, “Puna has been
a tremendous contributor to the SSR Mining portfolio over the last
two years, generating solid production and strong free cash flow.
This update features the first exploration drilling activity
completed at Chinchillas since before the mine commenced production
and demonstrates mineralization from near-mine and in-pit step-out
intercepts that bode well for potential extensions to Puna’s
current Mineral Reserve life. In addition, high-grade intercepts at
the Melina and Socavon Del Diablo targets indicate the potential
for additional open pit mining opportunities immediately adjacent
to the main Chinchillas pit, while positive results from the
Cortaderas target at the Pirquitas property could present a
longer-term development pathway for further mine life extension at
Puna. We have expanded the Puna exploration budget to 15,000 meters
in 2023 as we aim to accelerate Mineral Resource conversion and
expansion efforts.”

Significant intervals are reported using a 50 grams per tonne
(g/t) silver equivalent (AgEq) cut-off and with a maximum 3 meters
of contiguous dilution. All intercepts are core width
intervals.
Silver equivalent values are calculated using the following
metal prices: Silver (Ag) price of $22 per troy ounce, Lead (Pb)
price of $0.95 per pound and Zinc (Zn) price of $1.15 per pound.
Metallurgical recoveries for the Chinchillas operation were not
used in the calculation of AgEq values (recoveries were 95.7% for
silver, 92.3% for lead and 48.7% for zinc in 2022).
Overview of Puna
Puna is 100% owned by SSR Mining and is comprised of the
Chinchillas and Pirquitas properties (see Figure 1). SSR Mining
approved the start of the Pirquitas mine and processing plant in
October 2006, and the Chinchillas mine declared commercial
production in December 2018. Chinchillas is an open pit
silver-lead-zinc mine that provides all of the ore currently
processed at the Pirquitas processing plant, located 42 km to the
southwest. The processing plant produces a silver-lead concentrate
and a zinc concentrate that are shipped to international
smelters.
The Chinchillas and Pirquitas properties are located within the
Bolivian tin-silver–zinc belt that extends from the San Rafael
tin-copper deposit in southern Peru into the Puna region of Jujuy,
Argentina. These deposits are generally characterized by the
intrusion of dacite dome complexes with mineralization hosted in
shear zones and breccias within the dacite domes or within the
country rock. More rarely, as in the case of the Chinchillas
property, the deposits also contain disseminated flat lying manto
bodies within sedimentary and pyroclastic rocks that are cut by
‘feeder’ shears.
Chinchillas Property Exploration and Overview
The Chinchillas property is comprised of three contiguous claims
totaling over 2,000 hectares. The open pit Chinchillas mine
achieved commercial production in December 2018. As reported in the
2021 Puna Technical Report Summary (the “Puna TRS”), the mine has a
Mineral Reserve life extending through 2026 with an average annual
production profile of 7.0 million silver ounces. Over the next
three years, SSR mining expects Puna to produce 8.0 to 9.0 million
ounces of silver annually.
Significant silver-lead-zinc mineralization occurs in four main
areas at the Chinchillas property: the Silver Mantos and Mantos
Basement zones in the west part of the property, and the Socavon
del Diablo and Socavon Basement zones in the east part. Mining is
currently active at the two Mantos deposits, which remain open for
expansion to the east.
In 2022, SSR Mining had two drill rigs operating at the
Chinchillas property completing nearly 7,500 meters of drilling
across 46 drill holes (see Figure 2 and Table 5). Drilling was
completed within and around the margin of the open pit operation,
and focused on resource expansion and reconciliation drilling, as
well as testing a series of high potential targets including
Socavon Del Diablo and Melina along the northern rim of the
Chinchillas volcanic dome complex. Fieldwork earlier in 2022
focused on geological mapping and prospecting to help identify
mineralization and drill targets.
Drilling within the center of the current Chinchillas pit
successfully infilled sections of the Mantos Basement deposit,
returning broad intercepts of higher-grade mineralization that have
the potential to enhance the resource. Drill hole CHN22-347
intersected both the Silver Mantos (30 meters at 422 g/t Ag
starting 2 meters from surface) and the Mantos Basement deposit (34
meters at 198 g/t Ag starting 123 meters from surface) due to the
stacked nature of the two deposits, potentially extending the
deposits vertically and down-dip to the east (see Figure 3). At the
northeast end of the Chinchillas deposit, drill hole CHN22-349
expanded the shallow Silver Mantos deposit with mineralization
starting within 30 meters from surface (see Figure 2).
The undeveloped Socavon Del Diablo deposit is located
approximately 700 meters east of current open pit mining and
consists of near surface silver-lead-zinc mineralization hosted
within a clay-altered volcanic rock. A new metallurgical program
was initiated in January of 2023 to help evaluate the viability of
this deposit and its potential contribution to the Puna life of
mine plan.
At the Melina zone, located on the northern rim of the
Chinchillas dacite volcanic center, broad zones of mineralization
occur proximal to a brecciated volcanic-sedimentary contact that is
similarly hosting the Mantos Basement deposit 750 meters to the
west. Near surface mineralization at the Melina zone appears to
have a similar geometry to the Silver Mantos deposit.
Pirquitas Property Exploration and Overview
The Pirquitas property includes surface rights covering an area
of approximately 7,500 hectares, which includes the Pirquitas
processing plant and the Cortaderas deposit, as well as the past
producing San Miguel pit. The Cortaderas deposit is a
zinc-silver-lead deposit located approximately 500 meters to the
north of the San Miguel pit. Cortaderas is a structurally
controlled sulfide breccia deposit that trends southeast and dips
steeply (60-70 degrees) to the southwest. It has a strike length of
440 meters, a vertical extent of approximately 350 meters and
varies from 3 to 20 meters in thickness.
The current Cortaderas deposit includes a 1.46 Mt indicated
resource grading 203 g/t Ag and 7.1% Zn, and a 1.03 Mt inferred
resource grading 204 g/t Ag and 7.7% Zn. In 2022, 1,420 meters of
drilling was completed in two deep holes testing the western margin
of the Cortaderas vein-breccia deposit. Concentrations of vein-type
sulfide mineralization were intersected at the expected depth and
successfully expanded mineralization approximately 200 meters
further down-dip and to the northwest. Starting at a downhole depth
of 574 meters in DDH-398, an intercept grading 10.6% ZnEq was
intersected over 17 meters, including a high-grade sub-interval
grading 24.2% ZnEq over 4 meters. Approximately 40 meters to the
west, DDH-399 intersected 16 meters of mineralization starting at a
down-hole depth of 553 meters and grading 17.9% ZnEq. Within this
brecciated zone, 4 meters grading 26.2% ZnEq. With this successful
and aggressive step-out to the west, the 2023 drill program is well
positioned to continue testing along strike to the west and further
down-dip to the south.

Significant intervals are reported using a 50 grams per tonne
(g/t) silver equivalent (AgEq) cut-off and with a maximum 3 meters
of contiguous dilution. All intercepts are core width
intervals.
Zinc equivalent values are calculated using the following metal
prices: Silver (Ag) price of $22 per troy ounce, Lead (Pb) price of
$0.95 per pound and Zinc (Zn) price of $1.15 per pound.
Metallurgical recoveries for the Cortaderas deposit were not
used in the calculation of ZnEq values (recoveries were 81% for
silver and 91% for zinc in metallurgical analysis completed in
2018).
Technical Procedural Information
Sampling and Analytical Procedures
All drill samples in respect of the Chinchillas and Cortaderas
surface drilling program were analyzed at ALS Laboratories (“ALS”)
in Mendoza, Argentina. SSR Mining's drill and geochemical samples
were collected in accordance with accepted industry standards. SSR
Mining conducts routine QA/QC analysis on all assay results,
including the systematic utilization of certified reference
materials, blanks, field duplicates and umpire laboratory check
assays. Sampling interval was most commonly 1 meter, using
geological and/or structural criteria. ALS crushed each sample to
70% passing 2 mm mesh and a 250 g split was pulverized to better
than 85% passing 75 microns. A four-acid multi-element analysis
with a MS finish, using a 0.25 g sample, was used to produce Ag, Pb
and Zn analytical results. For all Ag, Pb and Zn results > 100
ppm (Ag) or >10,000 ppm (Pb and Zn), a four acid overlimit
method was completed using a 0.4 g sample size. Fire assay with an
atomic absorption finish was completed on a 30-gram aliquot to
produce gold analytical results with a 0.005 g/t gold detection
limit.
External review of data and processes relating to Chinchillas
and Cortaderas exploration data has been completed by independent
consultant Carl Edmunds in the first quarter of 2023. There were no
adverse material results detected and the QA/QC indicates the
information collected is acceptable, and the database can be used
for further studies.

Significant intervals are reported using a 50 grams per tonne
(g/t) silver equivalent (AgEq) cut-off and with a maximum 3 meters
of contiguous dilution. All intercepts are core width
intervals.
Silver equivalent values are calculated using the following
metal prices: Silver (Ag) price of $22 per troy ounce, Lead (Pb)
price of $0.95 per pound and Zinc (Zn) price of $1.15 per pound.
Metallurgical recoveries for the Chinchillas operation were not
used in the calculation of AgEq values (recoveries were 95.7% for
silver, 92.3% for lead and 48.7% for zinc in 2022).
NSI – No Significant Intercepts.
Figures presented in this table may not add due to rounding.

Significant intervals are reported using a 50 grams per tonne
(g/t) silver equivalent (AgEq) cut-off and with a maximum 3 meters
of contiguous dilution. All intercepts are core width
intervals.
Zinc equivalent values are calculated using the following metal
prices: Silver (Ag) price of $22 per troy ounce, Lead (Pb) price of
$0.95 per pound and Zinc (Zn) price of $1.15 per pound.
Metallurgical recoveries for the Cortaderas deposit were not used
in the calculation of ZnEq values (recoveries were 81% for silver
and 91% for zinc in metallurgical analysis completed in 2018).
