ARIS MINING ANNOUNCES HIGH GRADE DRILL RESULTS FROM ONGOING

SEGOVIA OPERATIONS EXPLORATION PROGRAM

Vancouver, Canada, August 16, 2023 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS;

OTCQX: TPRFF) announces the results received to date from its ongoing 2023 exploration program at its

Segovia Operations in Colombia. The 84,500 metre (m) exploration drilling program is now 58% complete.

Neil Woodyer, CEO of Aris Mining, commented “Our program encompasses the exciting work of discovering

new high grade vein structures near existing mine infrastructure. Drilling this year has successfully

intersected 32 different mineralized vein structures at strategically spaced drill points. Additionally, given

the widths and grades of vein intersections near active mining operations, this work is expected to convert

mineral resources i nto mineral reserves and to continue Segovia’s history of growth and reserve

replacement. Segovia has an impressive legacy of high grade gold production from numerous large scale ,

narrow quartz-sulfide veins for more than 150 years. Our exploration investment continues to result in new

high quality ounces and we eagerly await the results of the next phases of this program.”

The Segovia Operations exploration drilling program is a comprehensive undertaking with 17 drill rigs

operating in the El Silencio, Sandra K, Providencia, and Carla mines from 21 surface and underground drilling

chambers. As of a cut-off date of July 31, 2023, the Company has completed 48,964 m of drilling. The 2023

exploration program at the Segovia Operations has been designed to target the following objectives:

reserve replacement (29,000 m budgeted), expanding resources at existing operations (39,000 m budgeted)

and testing high priority exploration targets outside the current resource area but near mine infrastructure

(16,500 m budgeted).

Drill ing context

At the El Silencio Mine, 81 drillholes with full sample assays have been completed during 2023. At the 450

Vein, 16 holes with an average vein width and grade of 0.8 m at 34.09 g/t Au have been drilled into inferred

mineral resource volumes . These holes are located adjacent to existing mine workings and represent an

example of high impact exploration targets that can be accessed for incremental development capital. The

drilling at the 450 Vein includes four wider spaced expansion holes (100 by 45 m apart ), and 10 closer

spaced resource conversion holes on a 40 by 40 m grid . The majority of the holes with grades and

thicknesses above the economic mining cut-off assumptions at El Silencio are spatially continuous and are

expected to convert inferred mineral resources to indicated resources when active mining advances to

those locations. Also at the El Silencio Mine, five drillholes tested the west of the upper, western perimeter

of the mine into the brownfield Manzanillo vein target. This target was mined historically on four levels and

has had only 45 holes drilled by the Company since 2021. These holes were completed on a five dice pattern

100 m along strike and 45 m wide, with an average vein width and grade of 0.9 m at 17.04 g/t Au.

Additionally, the 2023 campaign includes 18 drillholes covering an 80 m wide grid pattern over a strike

distance of 200 m. This work intersected the brownfield Reliquia vein target, which is located 130 m above

the Manzanillo vein. Drilling at Reliquia returned an average vein width and grade of 0.7 m at 21.83 g/t Au.

At the Sandra K Mine, 32 drillholes have been completed. The 2023 program included 15 holes targeting

inferred mineral resource volumes of the Sandra K Techo vein. The average vein width and grade of these

holes is 0.6 m at 13.94 g/t Au. These holes are located down dip and to the east of the current mine workings

and significantly expand the down dip potential of the Sandra K Techo vein. Nearly all the drillholes have

sample lengths and widths above the economic mining assumptions for Sandra K and ar e expected to

convert inferred mineral resources to indicated resources when active mining advances to those locations.

At the Providencia Mine, 23 holes have been completed . A key target is the downdip extension of the

historically mined Marmajito vein, l ocated in the hangingwall of the Providencia vein and where 51

drillholes have been completed by the Company since 2021. These holes have an average vein width and

grade of 0.5 m at 13.14 g/t Au and are located on the edge of and outside inferred mineral resources, on a

100 m wide grid for 200 m along strike, with intersections completed at a 25 m by 25 m grid spacing. Most

of the holes have grades and thicknesses above the mine ral resource cut-off assumptions for Providencia

and are expected to convert to inferred mineral resources.

At the Carla Mine , 46 drillholes have been completed. 19 holes have been completed in the La Gran

Colombia vein over a 200 m strike length with an average vein width and grade of 1.2 m at 7.10 g/t Au.

These holes are located to the southeast of the current mine workings, spaced between 15 and 100 m from

the mining operations, with intersections completed at a 25 m by 25 m grid spacing, and are expected to

convert an area of inferred resources around 85 m long by 70 m wide to indicated resources as well as

provide greater accuracy of the vein location in other areas for the mine production teams.

Technical disclosure

All samples comprise half diamond drill core and were prepared and assayed by the commercial laboratory

SGS (ISO 9001:2008) located in Medellín, Colombia utilizing fire assay with atomic absorption finish and

with gravimetric finish for assays greater than 10 g/t Au. Aris Mining implements an industry standard

quality assurance and quality control program comprised of one certified standard and one blank submitted

with every 20 samples, and one field, one coarse, and one pulp duplicate every 50 samples. The re are no

known drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of

the samples disclosed in this news release.
