ARIS MINING ANNOUNCES HIGH GRADE DRILL RESULTS FROM ONGOING
SEGOVIA OPERATIONS EXPLORATION PROGRAM
Vancouver, Canada, August 12, 2024 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS;
NYSE-A: ARMN) announces the results received to date from its ongoing 2024 exploration drilling program
at its Segovia Operations in Colombia, which is now 70% complete.
Neil Woodyer , C EO of Aris Mining, commented “Our drilling program continues to deliver high grade
intersections, confirming the continuity and extension of the large scale veins at depth and along strike,
and supporting Segovia’s status as one of the highest grade gold operations in the world. The identification
of new, near mine mineral resources are expected to progressively lengthen the currently defined mine life,
and to provide future low development cost mill feed to supplement the processing plant expansion
currently underway. We are especially excited by the results of our ongoing data verification and new
drilling program s at Cristales, which are expected to result in significant additions to inferred mineral
resources and ha ve the potential to connect the Cristales vein with the substantial vein systems at El
Silencio”.
Exploration Program
The intersections provided in this news release include results received since the Company’s previous
exploration news release dated August 16, 2023 , which had a data cut-off date of July 31, 2023 , up to
validated sample assays available as of April 1, 2024 . These results are expected to be included in the
Company’s updated mineral resource and reserve estimates expected in the fourth quarter of 2024.
The Segovia vein system is extensive, with three of the four operating mines following relatively flat lying
vein systems ranging between 1.5 and 2.8 kilometres (km) along strike and extending down dip for between
2.0 and 2.7 km. To date, 80 different veins and vein splays have been identified from both surface and
underground drilling and underground channel sampling. Most of these large scale structures remain open
along strike and down dip. The majority of the exploration drilling is undertaken from with in the existing
underground mine development and support infrastructure, targeting vein extensions that require
relatively lower expenditures to develop and produce. As the vein splays are located in the footwall and
hangingwall of the main veins, most of the drillholes intersect multiple veins, providing a high value per drill
metre in terms of identifying new mineral resources , and often results in the discovery of new vein
structures.
Vein i ntersection grades remain high after diluting the vein width to the planned mining widths for
extraction using narrow vein mining methods. In addition to exploration drilling, ongoing channel samples
of the veins at the actively advancing work faces also continue to provide new data to upgrade mineral
resources to mineral reserves.
Exploration Drilling Results
Cristales is a historic operation that is currently being operated by a third party contractor for processing at
Segovia’s plant. The drilling strategy is to prove the extension of the Cristales vein at depth, which could

potentially connect to an existing crosscut at El Silencio, opening up a new mining front. The new drillholes
are located approximately 200 metres (m) to the south of the historic Cristales mine workings over an area
of approximately 250 m by 200 m , and supplement over 3,700 newly validated historic vein intersections.
These vein intersections are expected to result in new high grade inferred mineral resources. The new
drillhole highlights1 include:
• 0.32 m at 25.80 g/t Au in hole CR-ES-075
• 0.47 m at 7.48 g/t Au in hole CR-ES-080
• 0.31 m at 15.54 g/t Au in hole CR-ES-083
• 0.25 m at 137.78 g/t Au in hole CR-ES-086
Elsewhere, near mine drillholes strategically located approximately 100 m to the east and above existing
vein workings at El Silencio over an area of approximately 3 00 m by 120 m confirm the continuity of high
grade veins and were successful in extending the main vein in this area for another 500 m down dip. These
intersections are expected to drive growth of high grade mineral resources, which are important for
operations in the medium term. Drilling in this location was also successful in identifying a new vein in the
hangingwall and intersected other new veins with orientations oblique to the main structures. These new
veins will be a high priority for definition in our next drilling programs. Highlights include:
• 0.12 m at 45.19 g/t Au in hole ES-MH14
• 0.23 m at 55.22 g/t Au in hole ES-MH14-01
• 0.30 m at 61.50 g/t Au in hole ES-MH11-03
• 0.48 m at 61.82 g/t Au in hole ES-MH12-02
• 0.39 m at 28.34 g/t Au in hole ES-MH12-04
Infill and extensional drill holes over a strike of 2 50 m located to the northwest of El Silencio w ere also
successful in demonstrating continuity of the high grade veins, and are expected to result in new high grade
mineral resources and reserves, adding new production areas to the operations . Two new veins were
discovered in the footwall and hangingwall, and two other new veins related to a different structural trend
were also discovered. These new discoveries have been added to the list of high priority targets for
definition in our next drilling programs. Highlights include:
• 0.25 m at 15.20 g/t Au in hole ES-IU-182
• 0.20 m at 65.70 g/t Au in hole ES-IU-183
• 0.26 m at 715.99 g/t Au and 0.13 m at 93.34 g/t Au in hole ES-IU-191
• 0.20 m at 56.14 g/t Au in hole ES-IU-195
• 0.49 m at 118.75 g/t Au in hole ES-IU-202
• 0.14 m at 99.87 g/t Au in hole ES-IU-208
Surface drilling targeting a particularly rich vein located in shallower areas of the mine near the existing
operations over a strike distance of 240 m was successful in confirming continuity of the vein from the

surface. New mine development is now underway based on these successful drilling results, and with the
support of an updated geological interpretation, are expected to convert to high grade mineral resources
and reserves. Highlights include:
• 0.29 m at 536.75 g/t Au in hole MAN-ES-017A
• 0.39 m at 178.24 g/t Au in hole MAN-ES-020
• 0.19 m at 812.16 g/t Au in hole MAN-ES-021
Underground drillholes were strategically planned at that same high grade vein target over a strike distance
of 200 m to identify new mineral resources adjacent to the current mine infrastructure and to confirm
continuity at depth. This drilling was successful and is expected to extend our high grade mineral resources,
in addition to discovering a new vein in the hangingwall and two new veins in the footwall. Highlights
include:
• 0.40 m at 137.80 g/t Au in hole ES-EU-141
• 0.37 m at 15.37 g/t Au in hole ES-EU-145
• 0.28 m at 13.13 g/t Au in hole ES-EU-154
• 0.50 m at 26.93 g/t Au in hole ES-EU-158
Finally, a series of infill holes designed to upgrade and expand existing mineral resources at the Providencia
mine were drilled to test the downdip extension of a major high grade vein, with successful results that are
expected to drive the short and medium term mine production plans. Highlights include:
• 0.28 m at 29.61 g/t Au in hole MAR-IU-034
• 0.29 m at 11.10 g/t Au in hole MAR-IU-041
• 0.16 m at 207.79 g/t Au in hole MAR-IU-052
