Caledonia Mining Corporation Plc will publish its operating and financial results for the quarter ended June 30, 2026, on August 10, 2026. The announcement provides investors with a clear timeline for accessing the company’s latest performance data, allowing stakeholders to assess operational trends ahead of the broader market reaction. A remote presentation for analysts and investors is scheduled for the same day at 2:00 pm London time, followed by a question-and-answer session.

The procedural framework for the disclosure includes a webcast accessible via the company’s designated streaming link. Caledonia has confirmed that the presentation of the results and outlook will be available on its official website, ensuring broad access for shareholders who cannot attend the live event. This approach aligns with standard corporate communication practices for listed entities trading on multiple exchanges, including NYSE, AIM, and VFEX.

Presentation Details

The investor call focuses on reviewing the financial outcomes for the second quarter of 2026. Participants can register in advance to join the webinar. The schedule is fixed to accommodate international investors across different time zones, with the London time slot serving as the primary reference point.

Contact Information

Stakeholders seeking further clarification can reach out to the designated contacts listed below. The company has provided direct lines for internal inquiries as well as external support from its brokers and public relations firms.

What the Numbers Show

As this notice pertains to the scheduling of the results release rather than the results themselves, no financial metrics such as revenue, net profit, or EBITDA are currently available for analysis. Investors must wait for the August 10 publication to evaluate any year-over-year or quarter-over-quarter changes in performance. The absence of preliminary guidance in this filing means market expectations will rely entirely on prior analyst estimates until the official data is disclosed.

Caledonia Mining Corporation Plc has announced results from its surface exploration programme at the Blanket mine in Zimbabwe, revealing the presence of significant near-surface gold mineralisation in a previously unrecognised mineralised horizon. The discovery, centred on the K-Pits target area, has identified both oxide and sulphide mineralisation that has not been exploited by the existing underground mine operations.

Key Programme Highlights

The surface exploration programme delivered a range of significant findings across the K-Pits target area. The following summarises the key programme outcomes:

• Surface drilling confirms continuity of gold mineralisation below surface over the K-Pits target area
• Both oxide and sulphide mineralisation have been identified, supporting near-term and longer-term development opportunities
• Metallurgical test work is underway to evaluate the amenability of the oxide mineralisation to conventional heap leaching, with encouraging preliminary results
• Work is well advanced on an updated Blanket resource statement, expected to be published in August 2026
• Follow-up drilling is planned from both surface and underground platforms to test potential extensions of the mineralisation at depth

Selected Drilling Highlights

The following table presents selected drilling highlights from the Blanket surface programme. All intersections are downhole; estimated true widths are provided in the full appendix tables.

Overview of the Surface Exploration Programme

The Blanket surface exploration programme commenced in 2024 with geological mapping, geophysical surveys, trenching, and historical data collation. During 2025, a total of 2,304.1m of trenching from 13 trenches and a total of 7,063m of shallow RC drilling was completed at the K-Pit target, focused primarily on examining the area for oxide gold mineralisation amenable to low-cost surface heap leaching operations. The programme targeted the Banded Iron Formation (BIF) trending north-northwest, which has historically been mined at the nearby Vubachikwe and old Sabiwa mines.

Trenching at K-Pits comprised 13 trenches to a maximum depth of 1.50 meters, totalling 2,304.1 meters in length. All trenches were mapped for lithology and structure and sampled at 1.0-meter intervals along the sidewalls. On the strength of anomalous assay results, a grid on an approximate spacing of 25 meters x 25 meters was drilled utilising RC drilling. A total of 155 drillholes totalling 7,063 meters of drilling was completed, with all drillholes inclined at approximately 60 degrees to the west to an inclined depth of 45 meters, resulting in an approximate 40 meters vertical depth.

Significance of the Discovery

Geological interpretation suggests the K-Pits mineralisation may represent a separate mineralised system located approximately 200 metres east of the nearest projected underground orebody, raising the possibility that it constitutes a previously unrecognised mineralised horizon not exploited by historic underground mining activities. Analysis and interpretation of the results shows that the mineralisation is related to strong shearing and silicification on the contacts of the talc chlorite schist and the surrounding metabasalts.

The presence of near-surface oxide mineralisation is particularly significant because it may be amenable to conventional heap leach processing, potentially offering a lower-cost route to extracting gold compared to underground mining. Chief Executive Officer Mark Learmonth commented: "This is an exciting development at Blanket and further demonstrates the significant exploration potential that exists within the mining area. We have commenced metallurgical test work on the oxide material at Blanket to evaluate its amenability for conventional heap leaching and the preliminary results are encouraging. If the conclusion of the test work shows an acceptable recovery, we intend to commence a trial heap leach operation on an initial sample of 10,000 tonnes of material during the second half of 2026."

Next Steps and Resource Update

Further drilling is planned from both surface and underground platforms — including from 9 level underground — to probe the potential extension of the K-Pits mineralised zone at depth. The Company expects to publish an updated Blanket resource statement in August 2026, which will reflect the results of surface and underground exploration at Blanket alongside the exploration programme at Motapa, where encouraging initial drilling results were recently announced. The scientific and technical information in the announcement has been reviewed and approved by Craig James Harvey, MGSSA, MAIG, Vice President, Technical Services at Caledonia, who is a Qualified Person as defined under NI 43-101 and sub-part 1300 of Regulation S-K of the U.S. Securities Act.
