(\"Orosur\" or the \"Company\") (TSXV:OMI)(AIM:OMI), is\npleased to announce an update on the progress of exploration activities at the\nCompany's exploration project at Anzá in Colombia (\"Anzá\" or the \"Project\").\n\nAnzá - Colombia\nThe Anzá Project in Colombia comprises a number of granted exploration titles\nand applications totalling roughly 330km(2), within the Mid-Cauca gold belt,\nwest of Medellín.\n\nThese titles and applications are owned 100% by two Colombian companies,\nMinera Anzá and Minera Monte Aguila, both wholly owned subsidiaries of the\nCompany.\n\nSince acquiring 100% control of the Project, the Company has focussed its\nattention on three prospects:\n*\nPepas - a shallow, high-grade deposit of gold mineralisation for which the\nCompany has calculated a Mineral Resource Estimate (\"MRE\"), announced February\n10(th), 2026.\n*\nAPTA - a high-grade body of gold mineralisation that has to date seen\napproximately 40,000m of drilling, with drilling ongoing.\n*\nEl Cedro - a cluster of gold porphyry intrusions in the south of the Project\narea. Extensive mapping and sampling programs have been undertaken and a rig\nis currently being mobilised to commence the first drill program ever\nundertaken at the prospect.\n(https://app.accessnewswire.com/imagelibrary/933252f1-c5bf-488a-a878-b3d132cc2a3a/1201639/image.jpeg)\nFigure 1. Anzá Project\n\nPepas\nThe Company's primary focus since reassuming control of the Project in late\n2024, was to explore the immediate area of Pepas, ultimately leading to the\npublication of a maiden MRE for the Pepas gold deposit on February 10(th),\n2026.\n\nFollowing completion of the MRE drillout in late 2025, the Company then\nembarked on a semi-regional drilling program around the Pepas deposit. The\nobjective of this drilling program was to better understand the larger scale\nlitho-structural controls that led to formation of the Pepas deposit, such\nthat, in combination with additional mapping and sampling in the wider region,\nvectors toward additional mineralisation might be developed and ounces added\nto inventory.\n\nThe Company achieved immediate success with a new zone of shallow\nmineralisation being identified roughly 100m to the west of Pepas - with first\nresults announced on April 14(th), 2026.\n\nDrilling has continued sporadically at Pepas West, with occasional pauses to\nallow access tracks to be developed, however results from these six additional\nholes (PEP100 to PEP105) continue to demonstrate an extensive zone of\nsurficial, high grade gold mineralisation.\n\n Hole Number  From (m)  To (m)  Interval (m)  Au (g/t)  \n PEP100       18.15     24.15   6             0.65      \n PEP101       0         6.4     6.4           2.81      \n including    1         5.3     4.3           3.83      \n PEP102       0         6.85    6.85          2.18      \n including    0.9       5.15    4.25          3.24      \n PEP103       0         10.20   10.20         5.77      \n including    0         2.45    2.45          22.3      \n PEP104       0         19.8    19.8          1.77      \n including    9         18.85   9.85          2.71      \n PEP105       0         15      15            2.03      \n including    0         5.5     5.5           3.24      \n\nTable 1.

Plan of holes, Pepas West\n\nInitial drilling at Pepas West had suggested the zone was geologically similar\nto Pepas, with the same mineralising events, but with a different, parallel\nstructural setting.\n\nRecent drilling, however, is developing a more complex picture with the\nhigher-grade surficial mineralisation seemingly a mix of in situ and heavily\nweathered material that has potentially remobilised downslope from Pepas.\n\nWhile deeper zones remain unresolved, a picture is emerging of a flat lying,\nsurface mineralised zone of perhaps 10m thick, over a wide area, with\nmineralisation starting from near surface, grading between 1 and 5g/t Au, and\noften obscured beneath a thin veneer of barren transported soil.\n\nThe zone is extensively weathered, with scattered enclaves of fresh quartz\nveins, with very little residual geological or structural texture remaining\nand, as such, the original litho-structural setting is difficult to determine.\nAdditional drilling and geological studies will be undertaken to endeavour to\nunderstand the genesis of Pepas West.\n\nThe Company considers this free digging, flat lying, surficial, high grade\noxide gold mineralisation to be a high priority in a near-term production\nscenario, from the point of view of cost and time required to define, develop\nand mine. Thus, instead of the currently employed diamond-core drilling, the\nCompany will examine the potential of utilising a smaller auger rig to more\nrapidly define the volume and grade of this extensive surface zone, while also\nexamining the potential for an auger system to be used on a regional basis to\nsample beneath transported cover. This trial is expected to commence in coming\nweeks.\n\nThe current diamond rig will remain on site and be focussed on deeper drilling\naround Pepas West and other targets.\n(https://app.accessnewswire.com/imagelibrary/00d4ee9d-474a-45e0-bae1-d1a148713c19/1201639/image202608050007095wozn8.png)\nFigure 3.

(\"Orosur\" or the \"Company\") (TSXV:OMI)(AIM:OMI), is\npleased to announce an update on the progress of exploration activities at the\nCompany's exploration project at Anzá in Colombia (\"Anzá\" or the \"Project\").\n\nAnzá - Colombia\nThe Anzá Project in Colombia comprises a number of granted exploration titles\nand applications totalling roughly 330km(2), within the Mid-Cauca gold belt,\nwest of Medellín.\n\nThese titles and applications are owned 100% by two Colombian companies,\nMinera Anzá and Minera Monte Aguila, both wholly owned subsidiaries of the\nCompany.\n\nSince acquiring 100% control of the Project, the Company has focussed its\nattention on three prospects:\n*\nPepas - a shallow, high-grade deposit of gold mineralisation for which the\nCompany has calculated a Mineral Resource Estimate (\"MRE\"), announced February\n10(th), 2026.\n*\nAPTA - a high-grade body of gold mineralisation that has to date seen\napproximately 40,000m of drilling, with drilling ongoing.\n*\nEl Cedro - a cluster of gold porphyry intrusions in the south of the Project\narea. Extensive mapping and sampling programs have been undertaken and a rig\nis currently being mobilised to commence the first drill program ever\nundertaken at the prospect.\n(https://app.accessnewswire.com/imagelibrary/933252f1-c5bf-488a-a878-b3d132cc2a3a/1201639/image.jpeg)\nFigure 1. Anzá Project\n\nPepas\nThe Company's primary focus since reassuming control of the Project in late\n2024, was to explore the immediate area of Pepas, ultimately leading to the\npublication of a maiden MRE for the Pepas gold deposit on February 10(th),\n2026.\n\nFollowing completion of the MRE drillout in late 2025, the Company then\nembarked on a semi-regional drilling program around the Pepas deposit. The\nobjective of this drilling program was to better understand the larger scale\nlitho-structural controls that led to formation of the Pepas deposit, such\nthat, in combination with additional mapping and sampling in the wider region,\nvectors toward additional mineralisation might be developed and ounces added\nto inventory.\n\nThe Company achieved immediate success with a new zone of shallow\nmineralisation being identified roughly 100m to the west of Pepas - with first\nresults announced on April 14(th), 2026.\n\nDrilling has continued sporadically at Pepas West, with occasional pauses to\nallow access tracks to be developed, however results from these six additional\nholes (PEP100 to PEP105) continue to demonstrate an extensive zone of\nsurficial, high grade gold mineralisation.\n\n Hole Number  From (m)  To (m)  Interval (m)  Au (g/t)  \n PEP100       18.15     24.15   6             0.65      \n PEP101       0         6.4     6.4           2.81      \n including    1         5.3     4.3           3.83      \n PEP102       0         6.85    6.85          2.18      \n including    0.9       5.15    4.25          3.24      \n PEP103       0         10.20   10.20         5.77      \n including    0         2.45    2.45          22.3      \n PEP104       0         19.8    19.8          1.77      \n including    9         18.85   9.85          2.71      \n PEP105       0         15      15            2.03      \n including    0         5.5     5.5           3.24      \n\nTable 1.

Plan of holes, Pepas West\n\nInitial drilling at Pepas West had suggested the zone was geologically similar\nto Pepas, with the same mineralising events, but with a different, parallel\nstructural setting.\n\nRecent drilling, however, is developing a more complex picture with the\nhigher-grade surficial mineralisation seemingly a mix of in situ and heavily\nweathered material that has potentially remobilised downslope from Pepas.\n\nWhile deeper zones remain unresolved, a picture is emerging of a flat lying,\nsurface mineralised zone of perhaps 10m thick, over a wide area, with\nmineralisation starting from near surface, grading between 1 and 5g/t Au, and\noften obscured beneath a thin veneer of barren transported soil.\n\nThe zone is extensively weathered, with scattered enclaves of fresh quartz\nveins, with very little residual geological or structural texture remaining\nand, as such, the original litho-structural setting is difficult to determine.\nAdditional drilling and geological studies will be undertaken to endeavour to\nunderstand the genesis of Pepas West.\n\nThe Company considers this free digging, flat lying, surficial, high grade\noxide gold mineralisation to be a high priority in a near-term production\nscenario, from the point of view of cost and time required to define, develop\nand mine. Thus, instead of the currently employed diamond-core drilling, the\nCompany will examine the potential of utilising a smaller auger rig to more\nrapidly define the volume and grade of this extensive surface zone, while also\nexamining the potential for an auger system to be used on a regional basis to\nsample beneath transported cover. This trial is expected to commence in coming\nweeks.\n\nThe current diamond rig will remain on site and be focussed on deeper drilling\naround Pepas West and other targets.\n(https://app.accessnewswire.com/imagelibrary/00d4ee9d-474a-45e0-bae1-d1a148713c19/1201639/image202608050007095wozn8.png)\nFigure 3.

One half is kept on site in the Minera\nAnzá core storage facility in the case of the Anza Project, or on site in\ntemporary racks in the case of the El Pantano Project, with the other sent for\nassay.\n\nIndustry standard QAQC protocols are put in place with approximately 10% of\ntotal submitted samples being blanks, repeats or Certified Reference Materials\n(CRMs).\n\nSamples for holes PEP-001 to PEP-011 were sent to the Medellin preparation\nfacility of ALS Colombia Ltd, and then to the ISO 9001 certified ALS Chemex\nlaboratory in Lima, Peru.\n\nSamples from PEP-012 onwards are sent to Medellin laboratory of Actlabs for\npreparation and fire assay, with some sample then sent to the Canadian Actlabs\nfacility for multi element assay\n\n30 gram nominal weight samples are then subject to fire assay and AAS analysis\nfor gold with gravimetric re-finish for overlimit assays of >5 g/t. ICP-MS\nUltra-Trace level multi-element four-acid digest analyses may also undertaken\nfor such elements as silver, copper, lead and zinc, etc.\n\nGold intersections are reported using a lower cut-off of 0.3g/t Au over 3m.\n\nIntersections are quoted as downhole thicknesses. True thicknesses are\nunknown.\n\nForward Looking Statements\n\nAll statements, other than statements of historical fact, contained in this\nnews release constitute \"forward looking statements\" within the meaning of\napplicable securities laws, including but not limited to the \"safe harbour\"\nprovisions of the United States Private Securities Litigation Reform Act of\n1995 and are based on expectations estimates and projections as of the date of\nthis news release.\n\nForward-looking statements include, without limitation, the continuing focus\non the Pepas prospect, the exploration plans in Colombia and the funding of\nthose plans, and other events or conditions that may occur in the future.\nThere can be no assurance that such statements will prove to be accurate.\nActual results and future events could differ materially from those\nanticipated in such forward-looking statements.
