Colnet Lake Globex Property

Ownership
The property is owned 100% by Globex Mining Enterprises Inc.

History
Early work on the property likely dates back to the early 1920’s.  Very little information is available on this period but it is clear the area was known to have potential, especially for gold. 

Between 1927 and 1940 Minerals Exploration Ltd and Nordike Mine Synd worked in the Colnet area.  It was around this time that an adit was dug at the Lac Colnet Ouest showing.  Several small trenches and pits were also dug.  This revealed a 1 meter wide shear zone trending 015 N and dipping west.  This shear hosts quartz-carbonate veinlets with up to 3% pyrite and trace chalcopyrite.  Values of 1.03 and 15.77 g/t Au were reported from this shear zone.  Previous workers also mention a massive chalcopyrite lense up to 20cm wide and 6 m long located along the lake shore grading 11% Cu.  No record of this lens location remains and subsequent workers did not observe it in the field.

In 1947 Montserrat Gold Mines dug several trenches and pits and later drilled 7 holes on what is now the Montserrat showing. The best intersection from that campaign was 8.9 g/t over 0.76m.

In 1956 New Lorie Mines drilled 4 holes totalling 12 m on what is now the New Lorie Zn showing but did not sample the core.  Extensive stripping and trenching was also carried out in the area and a shaft was sunk.

Between 1974 and 1976 Yvanex Development Ltd covered the southern portion of the property with HEM and ground Magnetic surveys and reported three weak HEM anomalies. 

In 1979, Falconbridge Copper Ltd. carried out mapping (scale 1”:100ft) and geochemical sampling of the south-eastern part of the Colnet Lake property as part of a much larger program covering what they called the Four Corners property. They recommended a dipole-dipole I.P. survey over the north-east portion of the Globex claims in range I, particularly over the New Lorie Zinc showing.

Falconbridge followed up these efforts with a drill program across the Four Corners property from 1980 to 1981, which included three drill holes on the Colnet Lake property.  All three holes were drilled in the New Lorie Zn area as a follow up to the previously recommended I.P. survey.  The holes did not return any significant assays and later, workers have questioned whether they were adequately located and oriented. 

In February 1989, Ressources Yorbeau carried out a drilling campaign in Montbray Township including two holes on the Colnet Lake Property.  One hole was drilled on the Lac Colnet Ouest showing and one on the Alex showing; both of them were designed based on geochemical and geophysical anomalies and on geological context.  The best intersection was 2.59 g/t Au over 4.04 m in M-89-2, 2A.  Yorbeau also conducted a VLF survey, geological mapping and sampling in the north half of the Lac Colnet property and carried out a humus survey over the Lac Colnet Ouest showing from 1984 to 1985.  Yorbeau subsequently optioned the southern portion of their property to Exploration Brex Inc.

A year later in February 1990, Brex drilled 9 holes on the Lac Colnet property or immediately adjacent to it; they also conducted their own VLF survey on a portion of the property.  Drilling focussed on testing the granite/basalt contact, the Lac Colnet Ouest showing and the VLF anomalies.  The first hole was drilled on a strong VLF anomaly and intersected a 15 ft (4.6 m) quartz vein at the contact between unaltered and hematized granite.  Holes were subsequently drilled to test the southern and northern extension of this vein; the southern extension revealed the best values of the drilling campaign: 4.10 gpt Au over 5 ft (1.5 m).  The second best value was intersected in a hole drilled under the Lac Colnet Ouest adit: 3.10 gpt Au over 2.3 ft (0.70 m).  A hole drilled to test the downdip extension of the values reported by Yorbeau intersected 0.5 gpt Au over 9.14 m.

Mines Altavista Inc. then mapped and sampled the entire property at a scale of 1:5,000 and carried out detailed mapping of the New Lorie Zn, Montserrat and Lac Colnet Ouest showings in 1996.  A 15 m stripping of the Lac Colnet Ouest showing allowed for the collection of grab samples assaying up to 3.20 gpt Au believed to be the surface expression of veins intercepted in previous drilling.

More recently Globex acquired the property in 2007 and has carried out field work since 2008.  This work includes; ground prospecting, geological mapping at a scale of 1:2,500; channel sampling of the New Lorie Zinc showing; ground mag and an I.P. survey.  The best sampling results were as follows:

Geology
The rocks of the Colnet Lake property consist of variably silicified, chloritized, locally epidotized basalts and andesites and a medium to coarse grained granite.  The basalts are mainly fine grained massive and are intruded by quartz veins and stockworks in a variety of places.  The New Lorie zinc showing is hosted by rocks that are rhyolitic to dacitic in composition, but it has so far proven impossible to tell whether they truly make up a separate lithology or if they are simply intensely silicified basalts.

Most of the mineralization on the property consists of disseminated to blebby pyrite, associated with silicification or zones of quartz veining.  This mineralization is mainly found in both the basalts and the granite.  The New Lorie Zn showing displays a different style of mineralization, consisting of disseminated to semi-massive sulphides including pyrite, sphalerite and lesser chalcopyrite.  The Eastern Trenches and Galena Trench showings also display disseminated galena.

Grab samples thus far have returned several anomalous gold values (>100s ppb) and some encouraging Zn values at the New Lorie Zn showing (1.2 to 6.7% Zn); samples from the Montserrat showing have returned from 2.3 to 13 gpt Au.

There are various known showings throughout the Colnet lake property: 

New Lorie, Zn
The showing is made up of a historical strip zone, a cleared area that was probably once another strip zone, several trenches and a shallow shaft.  The New Lorie Zn showing consists of strongly silicified rocks of rhyolitic to dacitic composition, that are intensely fractured and host disseminated to semi-massive sulphides (at the stripped outcrop) to blebby sulphides (in the shaft).  These sulphides include pyrite-sphalerite and lesser chalcopyrite and vary in quantity and intensity throughout the showing.

Past drilling on this showing intersected up to 65% pyrite over 0.3 ft (9 cm) and 23% sulphides over 4.7 ft (1.4 m) but was apparently never sampled.  This drilling seems to have been oriented in a number of different ways;  possibly as a result of poor understanding of controls on the mineralization (which continues to this date).

Montserrat, Au
The Montserrat showing comprises a network of trenches and a shallow shaft.  Geologically the showing consists of fine to medium grained, moderately carbonate altered basalt with 0.5-5% cubic pyrite and arsenopyrite and 10 cm-1 m wide bull quartz veins.  The orientation of the veins is highly variable but a fold axis was measured at 160o.  Folding could partly explain the structural complexity observed on this showing.

Alex, Au
According to historical records the Alex showing consists of wide quartz veins in silicified Colnet Laek Granite with “an important amount of pyrite”.  The veins strike east-west and dip south and are reportedly range to 2 to 3 m wide.

Colnet Lake Ouest, Au
The Colnet Lake Ouest showing lies in range II, lot 36, immediately west of the Colnet Lake property.  According to historical records the showing is comprised of a 9 m long adit oriented at N60°E as well as trenches, stripping and four drill holes.

Geologically, the showing reportedly consists of “a network of shallow dipping metre-scale veins in silicified andesites”.  These veins are associated with a north-northwest trending shear zone that runs along the Colnet Lake  granite contact; this shear zone reportedly connects Colnet Ouest to the Montserrat showing.  There appears to be at least two orientations of veining that were intersected by historical drilling and stripped at surface; the best reported grades from stripping were 3.2 gpt, 2.8 gpt, 1.8 gpt and 1.0 gpt Au (believed to be grab samples), whereas the best drill hole intercepts were 4.24 gpt Au over 0.37 m and 16.10 gpt Au over 0.46 m.

Globex has also identified the following new showings during the 2009 exploration campaign:

Eastern Trenches, Au, Ag, Cu, Zn, Pb
This showing was identified by Globex prospectors and consists of a small network of trenches on the eastern edge of the property. Those trenches consist of boulders (presumably sub-outcrop) of moderately chloritized basalt with quartz veining and 0.5-1% disseminated pyrite as well as a minor disseminated galena.  Grab samples from these trenches returned up to 9.98 gpt Au (duplicate samples vary from 0.62 gpt to 9.98 gpt), 101 gpt Ag, 126 ppm Cu and 248 ppm Zn in different samples.

Quartz Boulder, Au
A bull quartz boulder approximately 2.5m x 2.5m was sampled by Globex prospectors and returned gold values ranging from 13.47 gpt to 21.77gpt Au (same sample); another sample of the same boulder graded 7.89 gpt to 12.48 gpt Au (same sample).  Prospecting in the immediate area of this boulder and mapping along the same grid line did not identify the source of the boulder although bull quartz abounds throughout the property.  While the boulder likely originates from the Colnet Lake Granite, the exact source of the boulder remains unknown.

Galena Trench, Au, Cu, Zn, Pb
This showing was identified by Globex geologist P. MacKinnon and technician P. Harisson during the mapping campaign.  It consists of a 10 m long trench with at 170° azimuth.  The rock consists of silicified basalt with quartz veins and the mineralization is made up of abundant galena, chalcopyrite and magnetite in the host rock.  The best grab samples included one sample grading 3.77 g/t Au and 1.49 % Zn, one grading 2.34 % Pb and one grading 0.62% Cu.

Conclusion
The Colnet Lake property shows excellent potential for gold, zinc and possibly for other metals as well.  The property is host to a great number of showings, some of which have seen very little serious follow up and many of which have never been drilled. Further exploration is required to evaluate the economic potential of the showings and more importantly to better understand the process that formed them.  A better understanding of the geological relationship between the various showings could help identify a larger scale exploration target.
