Exploration

Exploration by the Company
The Company has not conducted exploration on this property beyond a visual assessment of the small portion accessible from the main road and four test samples taken by the PAC to verify the presence of gold.

Drilling
No drilling was done on the Andramasina Property.

Sampling Method and Approach
Samples were taken from shallow pits being worked by local villagers. These were taken as select and chip samples of material broken with a geologist hammer. The samples were prospecting type samples and not take to check known results.

Sample Preparation, Analyses and Security
All samples were kept in the personal control of Christopher until delivered to Acme Laboratories in Vancouver, British Columbia for analysis.

Sample Preparation and Analytical Procedures
Samples consisted of 1.0 to 1.5 kilograms of small chips collected by PAC were placed in plastic bags and secured with wire ties. Acme used conventional 30 element ICP and gold by FA with AA finish.

Quality Control and Check Analytical and Testing Procedures
Christopher based much of the information in this report on historical data found in old reports and documents that appear reasonable and reliable. None of these give details on the analytical procedures, quality control or reliability checking that may have been done at the time.

Data Verification
Data generated by work done on the Andramasina property prior to Christopher's examinations was not verified beyond comparing information presented by different authors. Much of the information on the history of this property dates to the late 19th century and data is not well documented. The most recent information was obtained from documents produced by Madagascar government services and oral accounts from local inhabitants.

Adjacent Properties
Historical gold production came mainly from stream placers and associated lag deposits in saprolite throughout a region extending northward from the headwaters of the Mania River to the Onive River and beyond. These were worked extensively from about 1885 to 1950 by several small companies and entrepreneurs from which an arguably large but indeterminant amount of gold was recovered. Limited production came from near-surface underground workings confined to the weathered saprolitic horizon. There is little technical information available for any of the workings and it is not likely that geological studies were undertaken by mining groups of that era.

Mania, Nosivolo, Sakaleona Region
Gold was first discovered at the head-waters of the Mania River system about 20 km north of Miarinavaratra. This find was worked by the Merina government using thousands of slaves. Following the French colonization, several companies mined stream beds and perched terraces in the region. The gold-rush that followed, produced 'very rich' deposits at the head-waters of the Sakaleona River and in the Ampasary River to the south and Boulanger states that this resulted in 'intensive' mining that produced 'enormous' amounts of gold during a 20 year period and declared production for the region of 1,176 kg was a very small fraction of actual recovered gold.

Several bedrock deposits were worked on a small scale. Anecdotal accounts by Boulanger describe variably oriented, well mineralized quartz veins with pyrite and occasionally visible gold. These are always associated with competent gneissic banded quartzite beds and pegmatite. Gold grades are poorly documented.

Sarobaratra (Northern Region)
Alluvial placers and bedrock mineralization of the Sarobaratra area are located 15 to 30 km to the north of Project B7 along the same north to north-northeast trend. Bedrock gold is found in quartz veins and quartz stringer zones associated with competent gneiss horizons, pegmatites and thick-bedded quartzites. Mineralized zones exploited by surface trenching and shallow underground workings are traced over linear trends of up to 1 km. Garnet, sillimanite, relic pyrite and graphite are common associated minerals. Related alluvial and eluvial deposits were the main focus of mining.

Beginning in 1885, the area was worked by the government with several thousand labourers. Intense activity directed mainly at alluvial deposits followed and by 1912, most of these were worked-out. Attention then focused on eluvial or saprolitic deposits that continued until about 1950 when reserves ran-out. Bed-rock mineralization does not appear to have been pursued though a number of veins were worked in conjuction with saprolite/eluvial mining.

Amrondrona Deposit
This area is underlain by biotite rich mica schists and gneisses that have been injected with mineralized quartz stringers. Old workings extend to a maximum of 12m depth in pits and trenches following mineralization oriented north-west.

Andravoravo Deposit
This zone, the most northerly of several located along a northeasterly trending quartzite, consists of three quartz stringer zones oriented north-south over about one kilometer. Historical production is not available but samples taken by Rakotoarisaina suggest an overall grade of between 6 and 10 g/t Au.

Antanjondrava Deposit
This large placer deposit was situated on the north shore of the Onive River and is considered to be worked-out.

Sarobaratra Deposit
A stream placer deposit is reported to have extended 200m beyond the river banks in the 300m wide Sarobaratra valley. It was the most productive of the region with grades attaining 5 g/t Au. Rakotoarisaina reported that a perched alluvial terrace remains intact but the balance of the area appears to be worked-out. Rakotoarisaina mapped and sampled quartz veins up to 15m wide but did not publish analytical results.

Mineral Processing and Metallurgical Testing
No metallurgical testing was carried out on samples from the Andramasina Property.
