    1. MT DIWALWAL "A Mountain of Gold or a Myth" “Geology and Style of Mineralization”.

    2. Location of the Project

    3. Tenement Location Map

    4. Tectonic Map of Mindanao (Aurelio, et al, 1998)

    5. Geologic Map of Eastern Mindanao

    6. STRATIGRAPHY

    7. Geology & Mineralisation

    8. Structural Setting

    9. BUENAS TINAGO VEIN SYSTEM N65°W; East-West & N75°E, dips 45° to 55° SW & SE Strike length of 0.925km & vertical extent of 254m. More sheared, with sub-parallel NNE strike-slip faults & imbriccated low angle faults

    10. Composite Plan of Buenas-Tinago Vein (MGB, 2003)

    11. Buenas -Tinago Area

    12. Buenas-Tinago Vein: Massive, banded & sheared quartz-calcite vein with slivers & mega-clasts of chloritized volcanic host rock (L+925, Sunshine Tun., N65E,48SE). (MGB XI, 2003)

    13. Qtz-rich- calcite Buenas-Tinago vein w/ “phantom” fine crustiform-colloform bandings & siliceous-chloritic-sericitic-pyritic layers. Upper section is the sharp chloritic-sericitic-pyritic fault gouge contact w/ the volcanic host rock, (MGB XI 2003)

    14. Buenas-Tinago Vein - Alternating qtz-calc vn, brx vn & chltzd volc. host rock. Fine-coarse cockade brx texture (sample pick). Sil’d angular clasts of volc. rocks are cemented by banded qtz-calc-py (L+830, Sunshine Tun., N65W,38SW), (MGB XI 2003)

    15. BALITE VEIN SYSTEM N55°E; East-West & N75°E, dips 78°SE Strike length of 1.2km & vertical extent of 450m. Flares-up, bifurcates & horsetail upward Merges at L-570

    16. Composite Plan of Balite Vein (MGB, 2003)

    17. Balite Vein Area

    18. Agtuuganon Limestone, outcropping above 1000 metres elevation, and immediately overlying the eastern extension of the Balite vein system

    19. Balite Vein - Spectacular crustiform-colloform bands made of alternating qtz-calc-sil’d, chltzd ± py ± gold (L+751, Bullex, N84E,75SE ). Au assay ranges from 3- 25 g/mt with kicks of 267 g/mt (MGB XI, 2003)

    20. Balite Vein - Massive, banded, sheared and brxt’d qtz-calc vn w/ sliver of propylitized andesite. Right side is the sharp fault contact w/ the chloritic-sericitic/illitic-pyritic volc. rock (L+680,North Vein Split,N57W,82SW).

    21. Balite Vein sample, 22 ppm gold and 7 ppm silver (DJK, 1989)

    22. Specimen of typical quartz-anhydrite-calcite from the Balite vein. Five samples of this material averaged 36 ppm Au and 17.2 ppm Ag (DJK, 1989)

    23. Vein Morphology / Mineralization Widths from 0.3 to 15 m. (ave. - 2.5m.) Sigmoidal fissure veins / crystalline & clast-supported breccia veins Crustiform-colloform bands, comb & cockade breccia texture Quartz, quartz-calcite and calcite Bands contain chlorite-clay-pyrite ± sphalerite-galena-chalcopyrite, possibly tetrahedrite/tennantite. Gold + silver is erratic,in micron-sized, attached or locked with lattices of sulfides Au grades show positive correlation with the intensity of bands.

    24. Section showing Buenas-Tinago and Balite Vein (MGB, XI, 2003)

    25. MINERAL RESOURCE as of January 2003 (NRMDC, 2003)

    26. Detailed Geologic Map, TRIMA 2

    27. Geochem Map: Au

    28. Geochem Map: Cu

    29. Geophysical Survey

    30. Geophysical Survey

    31. Higanteng Bato, a gold mineralised silicified andesitic volcanics displaying hydrothermal breccia texture, TRIMA 2

    32. Close-up of Higanteng Bato, consecutive 2 m chip samples HZ059 to HZ062 average 1.28 ppm Au (DJK, 1989)

    33. Intense kaolinite-silica-? marcasite altered andesitic volcanics displaying possible hydrothermal eruption breccia textures, Higanteng Bato, TRIMA 2 (DJK, 1989)

    34. Pervasively silica-pyrite altered hydrothermal breccia section of Higanteng Bato.

    36. Aerial view of part of the Mamunga clay-pyrite-silica alteration zone, TRIMA 2, south west of Diwalwal (DJK, 1989)

    37. Road exposure of kaolinite-silica-pyrite altered andesitic volcanic, Mamunga prospect, TRIMA 2 (Au ranges from 0.05 to 0.37 ppm with a kick of 0.92 ppm in 2 m channel sampling interval)

    38. Pervasively quartz - kaolinite - pyrite altered volcaniclastics, Mamunga area, TRIMA 2
