The Alicia Project is located in the eastern part of the Zamboanga peninsula on the southern Philippines island of Mindanao within the province of Zamboanga Sibugay. The Alicia Project is about 5 km from the town of Alicia, population 37,000, and 10 km from the port of Malangas. Access by air is via Pagadian City airport approximately 60 km away. The Alicia Municipality has a stable governance supportive of the project’s development. The project is also situated on a relatively flat area with low lying, undulating topography.
The Alicia Project is a known gold occurrence recognized by the Philippine Mines and Geosciences Bureau as a Declared Mineral Reservation, a region set aside and prioritized for future mining. The Exploration Permit EP-009-2016-IX was granted in June 2016 covering 932 hectares. It is important to note that the right to explore also includes the right to mine, for a period of up to 10 years, providing that resource and environmental compliances are met.

- Previous fieldwork at the Alicia Project included detailed geological mapping, geochemical sampling and limited drilling.
- The twelve veins generally trend northwest-southeast and are grouped into three main vein structures:
- Sandi Vein in the east
- Baloy Vein in the central portion of the tenement
- Pamaraw-Sumihig Vein to the west
- Several semi-parallel subsidiary veins also occur.
- Veins host native gold, silver, galena, sphalerite, and pyrite minerals.
- High grade samples from shallow drilling into the Baloy Vein include:
- 1.2m of 116 g/t Au, 1,263 g/t Ag, 6.3% Cu, 6.5% Zn, and 47.9% Pb<
- 1.5m of 40.9 g/t Au, 437 g/t Ag, 1.1% Cu, 3.6% Zn, and 62.9% Pb
- Field Work on the Pamaraw-Sumihig Vein yielded:
- a drill intersection of 1.5 m of 13.86 g/t Au, 181g/t Ag and 4.8% Cu
- a grab sample returning 7.51 g/t Au, 55.2 g/t Ag and 1.76% Cu
- The Alicia Project is situated within a Declared Mineral Reservation determined by the Mines and Geosciences Bureau (MGB) in 1995 and is on a granted Exploration Permit.
- The Project is accessible by sealed roads, is proximal to power and towns, is 10 km away from a port facility at Malangas, and 60 km from an airport at Pagadian City.

Martin is a member of the Australian Institute of Mining and Metallurgy (AusIMM), the Australian Institute of Geoscientists (AIG). He is a West Australian geologist with over 22 years’ experience and sufficient experience of relevance to the styles of mineralization and types of deposits under consideration to qualify as a Competent Person as defined by the 2012 Edition of the Joint Ore Reserves Committee (JORC) Australian Code for Reporting of Exploration Results, Mineral Resources, and Ore Reserves.
The Philippines is recognized as one of the most prospective nations in the world for gold/silver and base metal resources. Having been exploited for its resources by the early Spanish colonialists, the country became a major world producer of gold and copper during the 1920’s and 1930’s.
The country is rich in mineral resources, formed by the collision between the Pacific and Asian tectonic plates. This produced numerous subduction and obduction zones that have, for the past 25 million years, provided significant volcanic activity. The voluminous magmas exploited zones of structural weakness and provided the heat source for numerous porphyries and epithermal precious metal mineral vein systems.
Major copper/gold resources are common throughout the archipelago and it is recognized that the amount of exploration carried out is insignificant compared to the resource and mining potential.
Past exploration has identified 3 major parallel gold-bearing mineralized quartz vein structures generally trending NW-SE and numerous semi-parallel subsidiary vein systems, as shown below. The quartz veins have an average thickness ranging from 0.5 m to 3.9 m wide and generally exhibit drusy, chalcedonic quartz with massive textures. The clay-silica alteration is right beside the vein and either in sharp or gradational contact with propylitic alteration. Minerals present are native gold, sphalerite, galena and pyrite.

Alicia Project – Vein Dimensions
The focus of artisanal mining and modern exploration work is centered on Baloy and Pamaraw Veins. Channel sampling along Baloy vein and shallow diamond drilling at the Dacula locality (Baloy vein) returned high grade gold and massive sulphides including:
- 1.2m of 116 g/t Au, 1,263 g/t Ag, 6.3% Cu, 6.5% Zn, and 47.9% Pb;
- 1.5m of 40.9 g/t Au, 437 g/t Ag, 1.1% Cu, 3.6% Zn, and 62.9% Pb; and
- a channel sample that returned 1,299.9 g/t Au and 332.6 g/t Ag
In the southern half of the Exploration Licence exploration work confirmed the mineralization was open along strike over at least several kilometres. Assays from rock-chip and grab samples returned anomalous gold values, including: 77.7 g/t Au, 54.5 g/t Au and 46.4 g/t Au.
Geological indicators highlight a well-developed epithermal system, with the anomalous Cu grades having been introduced into the system post the primary epithermal system. The presence of a mature epithermal system provides a much bigger resource target within the known mineralization of the Pamaraw Vein. Mineralization within the tenement is from both a deep-seated epithermal source (and a near-surface, high-grade base metal sulphide source. The overprint of two mineralized systems significantly increases the resource potential.
- Small scale mining commenced in the 1970’s to the south of the tenement where several workings are situated. During the 1980’s small scale artisanal mining moved north onto the project tenement area and focused on the Dacula area.
- Philippine National Oil Company, PNOC-DEC, explored the area for coal during the 1980’s. During exploration, observations and mineral analysis identified hydrothermal alteration and mineralization occurring within volcanic rocks with massive silica and hydrothermal breccias indicating epithermal gold mineralization. PNOC-DEC also carried out IP surveying identifying anomalies related to gold mineralization. This was followed up with intensive field work and sampling.
- Mining and Geosciences Bureau (MGB) also recognized potential and declared a Mineral Reservation in 1992, a region with land use set aside for future mining.
- Greater Arc acquired the tenement application in 2013 and carried out due diligence work confirming the auriferous nature of quartz and calc-silicate veins.
- EP-009-2016-IX was granted in June 2016.
- Since the exploration permit was granted, Greater Arc has carried out detailed mapping and geochemical sampling programs with some limited drilling. Further field work carried out by Greater Arc has also:
- Explored the Baloy Vein and confirmed high grade massive sulphides present within the footwall and along over 400 m of strike.
- Identified extensive calc-silicate alteration zones containing chalcopyrite, galena, and sphalerite confirming that base metal mineralization may have a base metal carbonate porphyry system as it’s source.
- Mapped a possible collapsed structure/caldera edge, which in combination with the presence of internal sulphide breccias supports the potential of a central porphyry.
- Established local offices and locally based exploration management team to plan and execute field programs to further develop the Alicia Project.
