New Richmond - Antimony, Gold
New Richmond Township, Quebec (NTS 22A/04)

Updated May 2016

Ownership and Location
Globex owns a 100% interest in 18 staked claims in New Richmond Township in the Gaspé region of Québec, located 6 Km north of the town of New Richmond. The property can be accessed from the town of New Richmond by following Fallow road to 5th line then to Dee road which crosses the NW corner of the property. There are several secondary roads which traverse the claims.

Geology
The property is underlain by the Ordovician / Silurian age sedimentary Garin Formation, part of the d’Honorat Group.  Rocks are generally fine- to coarse-grained siliciclastic sediments including ranging from black shale and siltstones to sandstones and conglomerates. 

The Garin formation is folded into large anticlinal and synclinal folds along NE–SW axes with shallow to moderate plunges of 15o to 60oSW.  The rocks are cut by faults (Harriman, Grande Cascapedia and others) which trend from NNE-SSW to NE-SW and are believed to be reverse faults with steep WNW dips.  The Harriman fault is approximately 12 km long and crosses the New Richmond property for more than 2 km. it is a known locus for known gold and antimony mineralization.  It is poorly exposed along much of its trend.  Felsic and feldspar porphyry dykes are known to intrude the structure.

Rocks in the area are cut by numerous fractures and smaller structures which may have been affected by the regional folding.

Gold and antimony (Sb, found mainly as the mineral stibnite) mineralization is related to cherty silica flooding in fold axes and fold noses in sediments in the Garin Formation as well as fill in structures and breccias including the Harriman fault.  There is also antimony sulphide replacement in conglomerate beds.

Exploration History
Globex’s New Richmond antimony-gold Property comprises the Harriman-1 showing which has seen sporadic exploration work since its discovery in 1917. A summary of exploration history of the Harriman-1 occurrence was compiled by Jean-Paul Barrette in 2010 (Quebec assessment report GM 65155) and is summarized below;

 1917

 Mailhiot, A.

In 1917, A. Mailhiot discovered a stibnite-bearing quartz vein.  He is reported to have dug a 30 m long trench along the structure and sunk two small shafts of 6 m and 12 m respectively. No assays are reported by Barrette in his summary. 

 1935-41

 Various

Numerous visits by government geologists during this period confirmed the presence of gold and antimony.  Selected samples reported gold assays ranging from 2.9 gpt Au to 8.8 gpt Au with antimony results ranging to as high as 34.1% Sb.

 1940-41

 Leclerc

The Leclerc family, who ran quarrying operations in the Gaspé during the period installed a concentrator, forge and generator at the Harriman-1 site and excavated a trench of 50 m length, 6 m in depth and 2 to 5 m in width. A hand dug 10 m deep shaft was also completed near the central section of the known zone.  No results of this work are known to be published although, anecdotally the family had shared information indicating grades obtained from the work ranged to 0.75 oz Au/ton (23.4 gpt Au) and 42.5% Sb. Work was not continued.

 1982 

 SOQUEM

SOQUEM conducted exploration on the property which consisted of; 32 km of line-cutting; 175 samples taken for soil, humus and stream geochemistry; 4.5 km of induced polarization and resistivity surveys. 

Geochemistry identified a large area of gold, antimony, mercury and zinc trending for over 250 m northward from the Harriman-1 site.  The mercury anomaly extends for over 800 m.  Several anomalous areas were trenched with low results returned which ranged up to 1.4 gpt Au and 0.8% Sb in selected samples. However, numerous targets remained untested by the company.

 1985

 Noranda/Cascapedia

Noranda optioned the Harriman-1 area from Cascapedia Mines Inc., an un-listed company, in 1985 based on results of a sample provided by a Mr. Leclerc which returned an assay of 1.89 oz Au/T Au (59.1 gpt Au). Noranda completed geological reconnaissance work and drilled 5 holes (L1 – L5) from 1984 to 1986 for a total of 533.5 m.  Hole L1 returned the most significant drill result; 0.23 oz/t Au (7.19 gpt Au) and 4.8% Sb over 1 foot (0.31 m) in a bluish quartz vein within a 12 feet (3.66 m) thick zone of silicified conglomerate.  Approximately 33 feet (10 m) along strike to the north, Hole L2 returned a result of 0.011 oz/t Au (0.34 gpt Au) with no Sb over 1 foot (0.31 m) also in a bluish quartz vein within the zone of silicified conglomerate over 18 feet (5.49 m).  Holes L1 to L3 tested the structure at a depth of approximately 30 m and along a strike of 44 m. Holes L4 and L5 drilled the same target strike length at a depth of 75 m.  No significant results were obtained although the silicification persisted to depth.

 1988-89

 Cascapedia Mines Inc.

Lines cut by SOQUEM were restored and 5 trenches were opened north of the main showing.  The northern extension of the Harriman-1 was discovered in 1 – 4 m wide silicified zones in conglomerate with or without stibnite.  Best gold values obtained from these ranged from 200 ppb to 996 ppb gold

 1991

 J-B Leclerc

An induced polarization survey was conducted on the property defining a 500 m long chargeability and resistivity anomaly extension of the Harriman-1 zone, trending N26E. No follow-up was reported.

 1996

 Caron et al

Prospecting 2.5 km to the south of the Harriman-1 discovered angular boulders which returned gold assays ranging to 660 ppb and antimony assays ranging to 1%, these samples were initially suspected of being fill taken from the Harriman-1 site.

 2007

 M. Boudreau & R. Lelievre

These prospectors have demonstrated the presence of outcropping and sub-cropping silicified and stibnite mineralized conglomerate to the south of Harriman-1 and silicified mudstone and conglomerate with felsic intrusives to the north of Harriman-1.

 

Outlook
Property exploration to date has primarily focused on the Harriman-1 Au-Sb showing where the Harriman fault has been suspected of driving the emplacement of Au-Sb mineralization.  Detailed testing in the form of drilling has occurred over a very limited strike length (50 m) and only to shallow depth (75 m) while geophysical and geochemical work indicate up to 1 km of strike potential for exploration.  Additionally, a larger study of local fold structures and related plunges on their influence on Au-Sb deposition as well as locating and studying the effect of quartz feldspar and felsic intrusions could assist in developing new, larger Gold - Antimony targets on the property and extending the Harriman-1.
