3. 3 What differentiates Compostela from other exploration plays in the Philippines? Uniquely, Comval Tribal Resources Corporation (Comval) has joined with the indigenous people of the region surrounding Monkayo in the province of �Compostela Valley� to exercise their preferential right to explore and mine any portion of their ancestral domain. This confers the project with the key milestone of achieving �Free, Prior and Informed Consent� (FPIC) of the local community, who enjoy a 30% free-carried interest in the project. Accordingly, no interference from any activist organisations has been experienced or expected in the future. The Philippine Mining Development Corporation (PMDC) has granted the Indigenous Cultural Community (representing 4 tribes) the OA over 950ha known as �Tribal Mining Areas�, TRIMA 1 and TRIMA 2. Again, uniquely, the OA confers the rights to commence exploitation (mining) without the requirement for further input or permitting from the authorities. The right geological address by virtue of being directly adjacent to �Mt Diwalwal� � an infamous gold rush area since 1983 and potentially host to a major Cu porphyry deposit.

4. 4 History of the Project A Japanese Geological Survey for copper porphyries was undertaken in the early 1970�s. In 1983 a local tribal member discovered gold in streams on Mt Diwalwal, sparking a gold rush that has been sustained to this day. At its peak, over 100,000 small-scale miners worked on Mt Diwalwal. In 1986, a company called Marcopper commenced exploration in the area, but its programme was terminated in 1992 as the company failed to obtain a renewal of its EP. However, sufficient soil anomalies in what is now TRIMA 1 and TRIMA 2 had been recorded for Mike Spadafora, Comval�s consultant geologist, to note the site�s potential. In 2006, Hawkeye (a Philippines exploration company) entered into a FTMA with the 4 tribes over their 30,000ha Certificate of Ancestral Domain Title. In 2008, Comval acquired an option from Hawkeye over EPA-1 (now TRIMA 1 and TRIMA 2) and EPA 2 (see map on slide 12) $3m has been expended building capacity on sustainable projects within the tribal community, obtaining FPIC as a precursor to acquiring the OA from the PMDC over TRIMA 1 (gold) and TRIMA 2 (Cu porphyry) and completing the ACA Howe Technical Appraisal Report. Compostela Mining Ltd. was established in the Isle of Man as a tax-efficient vehicle to take the project forward to an IPO on an appropriate stock exchange.

15. 15 TRIMA 1 (Tribal Mining Area 1) TRIMA 1 adjoins Diwalwal to the west: this �Gold rush area�, discovered in the early �80�s, is a high grade epithermal vein complex which has been the subject of intensive artisanal mining, reputed to have produced at least 11 million oz (over 340 tonnes) of gold. TRIMA 1 is contiguous to the western boundary of Diwalwal whose major vein systems extend along strike into TRIMA 1. The extent of the continuation of the vein systems into TRIMA 1 is to be verified in the next phase of the exploration programme. The area is host to several gold bearing quartz veins. Past geochemical sampling work has generated a number of gold anomalies in the south east quadrant of the area where initial exploration will focus. Work to date on TRIMA 1 has been limited to chip sampling of existing adits (previously worked by artisanal miners) and soil sampling near workings in the northwest corner of the area. A second (3,200 ha) area to the north of TRIMA-1 lies on strike and of similar lithology to rocks hosting the major vein systems of Mt Diwalwal. An Exploration Permit (EPA-2) has been submitted to carry out work over this area.

16. 16 TRIMA 1 � Future Work Program Grid entire area and carry out Digital Terrain Modeling Detail map and soil sample south east quadrant Structurally map disposition of Fregor vein system on surface to confirm extension of the Diwalwal vein system into TRIMA-1 Re-open old existing and previously high graded adits Geophysics � magnetics (entire area) Assess and plan drill targets

17. 17 TRIMA 2 Evidence of porphyry style copper/gold mineralisation. Cu soil assay values in two discrete areas, both open to the north Au values coincident with As values, particularly in east of TRIMA 2, Hill 631 and Mamunga Au zones in East correlate with silicate and sulphide mineralisation identified by TEM resistivity survey Pb association with gold may indicate high gold values Anomalous zones correlate well with historic anomalies

18. 18 TRIMA 2 � Future Work Program Closer spaced and extension soil sampling to improve interpretation and enable target definition. Geophysical surveys over entire geochemically anomalous area consisting of: Ground magnetics Dipole � Dipole IP (Previous work limited in area and partly inappropriate techniques for porphyry copper deposits) Topographical surveys along grid lines (necessary for IP depth estimation) XRF alteration study Design and execute preliminary drill program

24. 24 SWOT Strengths Operating Agreement � no further permitting requirements prior to commencing exploitation Positioning as �son of Medusa�s� Co-O mine with value potential > $350m Relationship with Tribes gives security over asset Ease of access and good infrastructure Weaknesses Mindanao�s reputation as a conflict zone � activities of MILF and NPA Early stage exploration play with no JORC/NI 43-101 compliant borehole data Potential delays and disruption to exploration programme caused by weather/landslides. Opportunities Early cash flow potential from small scale working of high grade gold veins in TRIMA 1 Accelerated development of TRIMA 2 copper porphyry through farm-in by major mining company Promotion of stock through regular releases of exploration results Threats Release of bonanza gold grades may provoke site invasion by artisanals Peso/US$ forex risk adversely affecting cost base

25. 25 Strategy and Objectives Obtain JORC compliant assessments of the mineralisation over both TRIMA�s with an initial focus on TRIMA 1. TRIMA 2 has potential to host near surface, bulk tonnage gold deposits (>1 g/t, open pit mineable), plus major porphyry copper/gold mineralisation at depth. Once a minimum gold reserve on TRIMA 1 has been identified, initiate small-scale (c 5-10kozpa) production using local toll treatment CIP facility and u/g mining contractor. Use cashflow to accelerate expansion of TRIMA 1 resource base. Once initial resource on TRIMA 2 identified, negotiate farm-in. Carry out groundwork over EPA-2, which has similar rock units to TRIMA 1 and 2, to explore for potential repeats of the Diwalwal style epithermal gold veins and further Copper/Gold porphyry systems.

29. 29 Social Responsibility Comval Tribal Resources Corporation is a unique Filipino mining project insofar as the 4 tribes who were signatories to the OA continue to hold a 30% interest in the project, having ceded the other 70% to investors who will manage and develop the project to the benefit of all stakeholders. To date Comval Tribal Resources Corporation have sponsored and supported numerous community based projects in and around Monkayo, the township nearest to the TRIMA and EPA areas. As part of CTRC�s Community Aid program, the Company provided assistance in an emergency, such as when a landslide hit Diwalwal in November 2008. CRTC was the only organisation in the area to provide emergency aid and goods.

31. 31 Appendix Notes on Filipino Mining Rights

32. 32 Appendix Notes on Comval Tribal Operating Agreement The OA between the 4 tribes and Comval Tribal is unique and falls outside the usual �title� contractual arrangements with the Government described above. Free, Prior and Informed Consent (FPIC) under the Indigenous Peoples� Rights Act grants to the indigenous peoples (the Tribes) certain preferential rights to their ancestral domains and all resources found therein. In the case of Comval, FPIC is deemed to have been granted as the Tribes have, self-evidently, title over their own ancestral domain. The National Commission on Indigenous Peoples are also a signatory to the OA endorsing this crucial point. Key clauses and features in the OA are: Contract area of 950 ha comprising TRIMA 1 (284 ha) and TRIMA 2 (666 ha). Term of 10 years (renewable) Royalty payable to PMDC of 5% of gross sales of gold and other mineral products or Net Smelter Royalty in case of mineral concentrates. Mining Operations shall proceed immediately consistent with relevant mining laws.
