2012 Annual Report
23
The identified zones consist of quartz (with sulphides)
and sheared and altered sandstone. High-grade gold
results, from rock chips targeting the gold mineralised
zone, returned up to 16.2 g/t Au.
The mineralised zones at Xa Loi display slightly
different characteristics to those at Me Xi. Notably,
there is a greater concentration of quartz sulphide
veins and the veins contain higher sulphide content.
There are also a higher proportion of graphitic shales
within the host sediments – this reflects a significant
change in the structural environment that hosts the
mineralisation.
3. Khe Fia Prospect
The Khe Fia Prospect is located east of the
Me Xi Prospect.
Work to date indicates that the Khe Fia Prospect
may have the same style of mineralisation as the
Me Xi Prospect – sulphide quartz vein/veinlet zones
hosted by shears. Rock chip samples have assayed
up to 8.36 g/t Au.
Vietnam summary
In summary, the geometry of the mineralised multi-
generational quartz veining zones, coupled with the
intensive silica-sericite, sericite-chlorite and argillaceous
alteration at Me Xi and Xa Loi, is indicative of a porphyry
copper-gold system at a high level of erosion.
The recent drill and trench assay results, together with
the discovery of a potential host source rock at Xa Loi
and Me Xi, reinforces the potential that both of these
prospect areas host large hydrothermal gold or porphyry
copper-gold deposits.
Plans for 2013
The program for the three prospects is designed to
achieve greater clarity over the structural geology and
to determine the geometry and extent of the potential
dilation zones. This will help to pinpoint the locations
of the quartz veins, and to ultimately identify the areas
of sizeable tonnage and high-grade gold mineralisation.
Axiom intends to intensify exploration activities
in the early part of 2013.
This will involve:
›
›
Soil ridge and spur sampling and mapping
– to locate sub-surface expressions of the
mineralised structures, as well as strike extensions
›
›
Trenching – to sample the sub-surface
mineralised zones
›
›
Mapping and sampling – to confirm and identify
the gold mineralisation grades and styles, including
definition of the controlling structures and
identification of the fault and shear zones
›
›
Diamond drilling to test the gold mineralised zones
