Xama Property Assessment Report
October, 2014
SUMMARY
The Xama property holds potential for the discovery of a porphyry molybdenum deposit similar
to Endako, 21 km to the northwest. Anomalous molybdenum values in stream sediments and
soils led to the discovery of porphyry style molybdenum mineralization within the Property at the
Owl (Minfile 93F 019) and Gel (Minfile 93F 020) showing areas by Amax and Anaconda in the
1960’s. The Property has been explored intermittently since that time with additional
prospecting, geological mapping, soil, rock and stream sediment sampling, ground geophysics
(IP surveys) and 875 m of percussion drilling in 18 holes.
This report describes a structural analysis of the Xama property and its regional setting. The
Property is located in central British Columbia, 160 km west of the City of Prince George, in the
Omineca Mining Division. It consists of seven BCMTO mineral tenures covering 3,579 ha.
Registered owners are John A. Chapman, Gerald G. Carlson, Garry D. Bysouth and Gary W.
Kurz.
The Property is located in the Interior Plateau of British Columbia, within the Intermontane Belt,
including late Paleozoic to late Tertiary sedimentary and volcanic rocks belonging to the Stikine,
Cache Creek and Quesnel Terranes. The Property lies within eastern edge of the Stikine
Terrane, near its boundary with the Cache Creek Terrane and immediately south of the Skeena
Arch. The Endako Batholith is the key geologic feature of the area, underlying much of the claim
group and extending for almost 100 km in a northwestern direction, with a width of up to 40 km.
It is a composite batholith that comprises five temporally distinct plutonic suites, only one of
which is mineralized.
The Property is underlain by plutonic rocks of the Upper Jurassic Francois Lake Suite of the
Endako Batholith. A few outcrops of Casey Alaskite, belonging to the Endako Suite, occur in the
southern and central parts of the property and quartz diorite is well exposed along the high ridge
south of the claims. Two areas of molybdenite mineralization have been defined on the
Property. The largest of these is the Gel Zone which lies in the southeast part of the Property
east of Skip Creek. It has been defined by soil geochemistry, an IP survey and a line of eight
percussion drill holes. The second area lies in the southwest quadrant of the Property, west of
Skip Creek and is referred to as the Owl Zone. It has been defined by three percussion holes
drilled near two areas of surface quartz-molybdenite mineralization. Depth continuation was
confirmed in both areas. The major host rock in both zones is a dark green rock of either dioritic
or andesitic composition.
In this study, topographic features and airborne geophysical patterns, viewed as overlays on the
BC government MapPlace web site at 1:1,500,000 (regional) and 1:100,000 (local) scales have
been used to define linear features. It is assumed that, in many cases, these features represent
zones of crustal weakness, likely faults and fractures.
On a regional, 1,500,000 scale northeasterly linears, roughly parallel with the Skeena Arch,
dominate, along with a significant north-south linear that corresponds with the Fraser River
valley, through Prince George and Quesnel, and the strong east-west linear that cuts through
Prince George and Vanderhoof, just to the south of Endako and just north of the Property. Of
particular interest is a swarm of north-south linears through the central portion of the study area.
The Xama property is located near the intersection of the important east-west linear, a strong
northeast trending linear and a weaker north-northeast linear. Many of the known porphyry-style

deposits in the district may occur within specific, fault-bounded blocks rather than directly along
regional linears. At this scale of examination, it may be equally important for a
deposit to be
proximal to a linear as to be directly on it.
At the Property scale (1:100,000), many of the linears are sub-parallel to, but not exactly
coincident with, mapped faults and contacts from the BCGS MapPlace geology map. In many
cases, they are probably reflecting the same features, but in others, they are clearly distinct.
According to Lowe et al, (2001), most of these, especially NE and NW structures, are Tertiary
structures and therefore post-mineral.
Not reflected in the mapped geology are north-south linears that appear to be important and
potentially related to the known mineralization, as reflected mainly in the magnetics as lows,
possibly caused by magnetite destruction due to hydrothermal fluids and, more regionally,
gravity trends. The most important of these cuts directly through the Gel Zone.
The target deposit type at Xama is an Endako style porphyry Mo (Cu) deposit or, secondarily, a
bulk tonnage Au-Ag deposit, such as Blackwater. Both deposit types would be expected to be
related to high level intrusive activity and demonstrate structural control. The key exploration
target suggested by this study is defined by the known porphyry-style molybdenum
mineralization at the Owl and Gel Zones, the magnetic low embayment in the area of these
showings that could be a reflection of magnetite destruction by mineralizing fluids, as well as
linears, likely structures, that are reflected in the magnetic data and may control the
emplacement of intrusions and related hydrothermal activity.
A 2,000 m Phase I drill program, targeted utilizing the results of this study in combination with
existing geological mapping, surface geochemical sampling, IP surveys and percussion drill
results, is recommended to test the Owl and Gel zones at depth.
