Disclaimer This document contains certain "forward–looking statements", including, but not limited to, statements concerning current and future drilling programmes, estimation of mineral resources, the continuing development plan, the type of mineralisation present and expected results. Information inferred from the interpretation of drilling results may be deemed to be a forward looking statement, as it constitutes a prediction of what might be found to be present when and if a project is actually developed. Statements and estimates concerning mineral resources may also be deemed to be forward looking statements in that they involve estimates, based on certain assumptions, regarding the mineralisation that would be encountered if and when a mineral deposit is actually developed and mined. Forward looking statements are not historical facts, and are subject to a number of risks and uncertainties beyond management’s control. There can be no assurance that such statements will prove to be accurate. Actual results and future events could differ materially from those anticipated in such statements. Risks and uncertainties that could cause results or future events to differ materially from current expectations expressed or implied by the forward–looking statements include, among other things, but without limitation, those set forth in the Annual Report and the website (www. interbasemetals. com) of International Base Metals Limited (IBML).

Appendix Omitiomire Project Details 33

Omitiomire Project – Geological Setting § Two basement domes; partly bounded by large thrust zones § Omitiomire deposit and other copper prospects are hosted by metamorphic rocks of the Ekuja Dome § Domes consist of quartz-feldspar (‘felsic’) gneiss, amphibolite and biotite schist 34

Omitiomire Project – Geological Setting 35

Potential In Pit Resource Increase 36

Potential Adjacent to Pit Resource Increase 37
