Highlights of Jaburi license
- It's one of Meridian's highest grade and quality Manganese oxide targets
- The Jaburi license is located adjacent to the Jaburi and
Rio Madeira plants - The pre-production grade control has been completed prior to C&M
Geology and Mineralization
Meridian licence 886643/2008 is located on the southern margin of the Espigão Project Area, and hosts the Jaburi Plant infrastructure (Figure 1). Manganese oxide vein systems are hosted by fine-grained granites in the area. Gabbroic to pyroxenitic intrusive stocks and dykes locally cut the granite basement. Mineralized structures typically trend east to east-north-east, and are cut by north-west trending cross faults. The licence area straddles the hinge zone to the deep-seated boundary fault separating younger sediments of the Pimenta Bueno graben to the south from the crystalline basement to the north.
The licence area hosts many of the higher-quality occurrences of manganese oxide. The occurrences contain lower levels of trace metal impurities, and have a higher proportion of the ore mineral "pyrolusite" (MnO2 – a high tenor manganese mineral). Past analyses of product stockpiles have reported maximum assay values of 59.4% Mn. The region occurs in a more stripped regolith profile on ground rising from the lowlands of the basin area to the south, and thus lack the laterites that are associated with some of the past regional production areas on the plateaus of the Espigão Project. The low phosphorous contents, the high Mn:Fe ratios, and the low levels of accessory metals have made the Jaburi manganese oxide concentrates a targeted product for blending in speciality alloys, and for fertilizer products.
Past extraction has been targeted from a range of prospects: Jaburi 1 - 5, Jaburi East, Jaburi West and Jaburi Novo. Production went into a hiatus period in
The Jaburi licence is also of interest in hosting the SW extension of the Gracioso Target – an area of iron-oxide breccia accompanied by coincident conductivity and radiometric anomaly (high total count; high uranium). This along with other deep-seated magnetic and conductivity anomalies1 will form part of a future focus on Cu-Au exploration, based on an exploration model for a zoned polymetallic mineral system2.

FORWARD-LOOKING STATEMENTS
Some statements in this presentation contain forward-looking information or forward-looking statements for the purposes of applicable securities laws. These statements include, among others, statements with respect to the Company's plans for exploration, development and exploitation of its properties and potential mineralisation. These statements address future events and conditions and, as such, involve known and unknown risks, uncertainties and other factors, which may cause the actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the statements. Such risk factors include, among others, failure to obtain regulatory approvals, failure to complete anticipated transactions, the timing and success of future exploration and development activities, exploration and development risks, title matters, inability to obtain any required third party consents, operating risks and hazards, metal prices, political and economic factors, competitive factors, general economic conditions, relationships with strategic partners, governmental regulation and supervision, seasonality, technological change, industry practices and one-time events. In making the forward-looking statements, the Company has applied several material assumptions including, but not limited to, the assumptions that: (1) the proposed exploration, development and exploitation of mineral projects will proceed as planned; (2) market fundamentals will result in sustained metals and minerals prices and (3) any additional financing needed will be available on reasonable terms. The Company expressly disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise except as otherwise required by applicable securities legislation.
The Company cautions that it has not completed any feasibility studies on any of its mineral properties, and no mineral reserve estimate or mineral resource estimate has been established. In particular, because the Company's production decision relating to Meridian Mineracao Jaburi S.A, manganese project is not based upon a feasibility study of mineral reserves, the economic and technical viability of the Espigão manganese project has not been established
