2012 Annual Report
Within the property area, several north-west trending
fold hinges have been identified from surface geological
mapping and structural interpretation. These, along
with the east-west trending mineralised structures,
suggest the possibility that the gold mineralisation is
similar to that of the Ordovician sequences in Eastern
Australia and Bendigo to Stawell in Victoria.
The three primary targets for economic gold
mineralisation at Quang Tri:
1. Me Xi Prospect
The Me Xi Prospect is located in the central portion
of the Quang Tri MEL. Since late 2011, surface and
artisanal miner’s tunnels, mapping, rock chip
sampling, channel sampling and trenching activity
have all contributed to the successful delineation of
several mineralised gold structures at Me Xi. Gold
mineralisation, with coincident anomalous arsenic and
controlled by east-west trending shears, has developed
in the Ordovician-Silurian aged sedimentary rock
package based on the work done so far.
The major shear zone identified to date is
approximately 500m in strike length and varies
between one and five metres in width. Results are
highlighted as follows:
›
›
To date, the highest gold grade encountered is
82.6 g/t Au from quartz sulphide vein material
›
›
Trenching returned positive results, including 51m
@ 0.93 g/t Au and 9m @ 1.61 g/t Au, representing a
continuous zone of gold mineralisation
›
›
Five diamond holes totaling 546.1m, with two holes
intersecting a mineralised zone:
–
–
1.00m @ 1.57 g/t Au from 95m (LK4-MX)
–
–
1.00m @ 2.04 g/t Au from 56m (LK11-MX)
2. Xa Loi Prospect
The Xa Loi Prospect is located immediately to the west
of the Me Xi Prospect. Previous investigation by the
General Department of Geology and Minerals, together
with further exploration by Axiom, have identified two
parallel gold mineralised zones, varying from 300-
500m in length and 3-7m in width.
