Brighton Mining Group Limited is an exploration company with a focus on gold exploration within Cambodia. Brighton has very promising exploration projects that are located in the gold rich province of Mondulkiri with hosts the Oz Minerals project of "Okvau".

Brighton's business model is centred around the exploration and development of its current portfolio of assets in Cambodia, with the potential for further acquisitions in Cambodia and the surrounding South East Asian regions to ultimately create wealth to its shareholders.

Antrong Concession, Cambodia

The Antrong Concession is located 230km north-west of Phnom Penh in the province of Mondulkiri. The Concession called Antrong covers an area of 58.5km2 and is approximately 9km north east of the Okvau project of OZ Minerals Limited in the mineral rich area known as the Antrong Mineral Field or Antrong Project. The Concession falls within the Antrong granodiorite and the wide hornfels halo that surrounds it with prominent north-north-west and north-south shear structures emanating from this instrusive. This geology is very similar in style to that hosting the Okvau project.

Although this region is relatively underexplored, many high grade gold bearing lodes have been identified by other companies including the discovery by OZ Minerals Limited along or around this wide hornfels halo. The geological work including drilling already carried out in the direct vicinity of the large Antrong granodiorite has demonstrated the potential for the area to contain multimillion ounce gold deposits.

Brighton has already completed metallurgical testing from three bulk samples taken from trenches and historical pits within the Antrong Concession and the test results showed a combined gravity/leach gold recovery of 92.8% at 75 micron leach grind. These tests also showed that the ore would be amenable to conventional carbon-in-pulp (CIP) processing achieving reasonably high extractions. The gold demonstrated some slow leaching characteristics requiring further investigation during the next metallurgical test work program.

The exploration budget for the first two years under this Prospectus totals approximately $1,290,000 (of which Brighton has allocated up to $750,000 for exploration on the Antrong Concession). This budget will allow the Company to carry out soil, trench and rock chip sampling combined with limited ground geophysics and relatively shallow drilling in order to confirm the stratigraphy on the Concession, to confirm mineralised targets, and to confirm the prospectivity and styles of mineralisation on the Concession.

Subject to exploration success following this proposed two year exploration programme, the Company will require additional capital in order to conduct further geochemical testing and to progress the Concession into the feasibility and resource definition stages in future years.

Ropoah Concession, Cambodia

The Ropoah project is located 230km north west of Phnom Penh in the province of Mondulkiri, and is approximately 5 km east-north-east of the Company's Antrong Concession. This Concession has an area of 11km2 and shares a very similar geological setting to the rest of the Mondulkirri mineral field and particularly that of Antrong. The Ropoah Concession covers the north-eastern margin of the Antrong granodiorite, along with the alteration halo, and then extends into the surrounding sediment. The two controlling factors of the mineralisation in this area come from the fractures that occurred during the granodiorite emplacement and with the axial plane cleavage of the folded sediments.

Kang Roland North, Cambodia

The Kang Roland North Concession covers a total land area of 146km2 and is located 18km north of the Antrong Concession. This Concession is the most recent in the Antrong Pproject area and consequently has not had as much exploration carried out on it as the other Concessions, and for this reason is probably considered to be a "greenfields" type prospect. However, due to its geological nature having many similarities to the other Concessions, it should have significant exploration targets generated in the near future.

The Concession itself contains two granodiorite intrusive structures which are similar to but smaller than the Antrong Concessio's intrusion. It is believed that these structures could be part of a much larger complex underneath the surface, resulting in the circular alteration systems and patterns observed on the satellite imagery of the area.

The geology also indicates that a series of radiating structures originating from the circular alterations may have been a result of emplacement of the larger intrusive body underneath the surface.

Brighton has allocated approximately $350,000 to spend over the next two years from the total exploration budget for the Kang Roland North Concession.
