Rousseau Property - Gold Royalty
Rousseau Township, Quebec (NTS 32E/03)

Updated May 2020

The property is a gold prospect in the Mistawack granite batholith 4500m north of its south contact with volcanic rocks (figure 1). Four quartz veins are exposed on the property to the north of a northeast-striking diabase dike of the type common to Northwestern Quebec. Gold occurs in free state in quartz veins and silicified granite found in a fractured and sheared zone in granodiorite.

By analogy to the geologically-similar environment in the Bourlamaque Batholith and to the numerous gold zones known to be related to periods of structural deformation of acid intrusive. The results obtained to-date by bulk sampling (see history of exploration section) show that the property has a good exploration potential and warrants further work.

It is therefore recommended that the exploration work program be done to further evaluate the potential of the property. This program ought to consist of a geological compilation and geophysical surveying, further prospecting and diamond drilling to test the best geophysical targets outlined.

Description of the property, location and access
The property consists of 12 claims covering 470 Ha. The lots are number 49 to 58 in range I of Rousseau Township. The property is located in the southeast quarter of Rousseau Township. It is easily accessible by a good road network. One of the road lies along the common township line and transgresses the south of the property in an east-west direction.

History of exploration
The history of the property dates back to the late 1920’s when it was explored by two shallow shafts, pits trenches and limited diamond drilling on Main vein and Mercier Vein. The Main vein was explored through 1.5m/3m shaft to deep for 13.7m and Mercier vein by a 1.83m x 6m to a deep of 4.9m (Teck Hugues Gold Mines Ltd., GM2920).

The property was dormant until early 1950’s and only re-sampling the gold zones on surface and in the shafts was done in 1954 (MNRQ, GM 2990).

From 1958 to 1979, limited geophysical work and drilled holes were done. In 1979 International Standard Ressources LTD. Optioned the property and intensified exploration was done between 1980 and 1989.

In 1980 more geophysical work and drilled holes (1944m) were done. Main vein was further explored by underground work, a ramp to a depth of 91m, 428m of drift and 188m of cross cut. From drifts and cross cuts 912m of drill holes was done (GM 38587). A sample of 75.6 short tone returned 0.466 opt of gold and 2.14 opt of silver (interne report by Bowdidge, in GM 53159). At the same time geological investigation and magnetic survey were done (GM37243) followed by 992m of drilled holes on the Main vein west extension (GM38587).

In 1982 tailings park and small mill of 150 ton per day were built. One ton of concentrate assayed 341.37 g/t of gold and 537.22 g/t of silver (interne report by Bowdidge, in GM 53159).

In 1985 calculated reserve returned 39600 ton at 13.t g/t of gold (Magnum, 1986, in GM 53159).

In 1988 and 1989, two holes campaign were done by International Standard Ressources , 1521m on the Main vein and Mercier vein completed by 1524m of holes are drilled on Mercier vein.

In 1992, the property was optioned by Ressources Mining Canaco Ltee., the mine was dewatered and drifts were systematically sampled. Mercier vein, third vein and fourth vein were mapped and sampled and mineralized zones were surveyed by VLF and IP.

In 1994 Canaco drilled 665m of holes to test vertical extension of Main vein (3 holes) and Mercier vein (1hole). Best assays on Main vein returned by holes No1 and No.2 were respectively 1533ppb Au/t /50cm and 2383ppb Au/t /70 cm. Best assay on Mercier vein was 10.17 g Au /t/30cm.

The property is a gold prospect found in the Mistawack granite batholith near its south contact with volcanic rock. The property is underlain by hornblende granodiorite which is part of the Mistawack Batholith. The granite is intruded by linear northeast – striking diabase  dike found to the south of the showing area in lots 52 - 53.Where exposed in the showing   area, the granite exhibits an increase in quartz content, is pink-cream in color, with biotite replaced green chlorite. It is composed of 60% pink to cream-colored feldspar and 40 % quartz    and exhibits a coarse porphyritic texture with quartz phenocrysts (1-5mm) in a feldspar matrix.

The Mistawack granite batholith has a composition ranging from granodiorite to quartz-diorite and is similar in composition to the Bourlamaque batholith. Both batholiths are anomalous in sodium and, this type of intrusive is considered a favorable location where to prospect for gold deposits. 

The diabase dike exposed south of the showing area well defined by the magnetic survey; it’s a normal diabase common to Northwestern Quebec. The dike exhibits chilled contact and is composed of pale green feldspar and black ferromagnesian minerals. Another dike in the vicinity of the Mercier shaft was intersected in two shallow holes drilled to test the Mercier vein. Underneath the shaft, in both holes, the dike is composed of small feldspar laths in a silicified basic matrix and could be an altered diabase dike, parallel to the main dike.

Gold mineralization
Gold is found at two locations on the property, in the Main vein and the Mercier vein Gold is also reported to occur in a vein 50 feet to the north and parallel to the Mercier vein (figure 3). The gold showing are found near the center of lots 52 and 53, range I, Rousseau Township, in granodiorite, 200 to 300 feet northwest of a northeast-striking diabase dike. Free gold occurs in cherty grey to milky quartz veins and in silicified granite adjoining the quartz veins. Gold is not related to the pyrite content of the vein and the granite walls. In several places the quartz is granular and free gold is found along small gash or tension fractures in quartz or in quartz near its contact with chlorite – filled fractures or the granite walls. Quartz veining and granite silicification are found in well-defined zones of sheared and fractured granite containing fault gouge and mud.

Four veins are exposed to the north of a northeast-striking common diabase.

Main Vein
The Main vein is located near center of lot 52, range I, Rousseau Township. It consists of irregular milky quartz vein (5-40cm) with an average of 30cm contained in a fractured zone. Quartz veining appears to have been introduced along the mud filled fractures and in places, recurring movement along fractures brecciated and rounded off some of quartz fragments. In the vicinity of the main shaft, the fracture zone (5-15cm) contains an average of over 30% quartz occurring in echelon along the fracture zone. The main vein strikes N58W and dips 85°N. In the shaft area, the vein turns abruptly to the south and strikes N15W and joins up with another vein parallel to the main vein (GM 36227). On the surface, the vein outcrops for a length of 9.2m and one of the main quartz vein in the fractured zone is reported to have returned 3 Oz /T Au /30.5cm . In the shaft, it returned 1.34 Oz/ T Au/ 76.2 cm. At the bottom of the shaft, it is reported to have assayed 3 Oz/t Au/ 76cm. At that time a 9.54 ton bulk sample made out in part from material mined out from this part of the main vein exposed on surface and from material taken from the dump was shipped to the Noranda smelter and returned 0.65 opt of gold. Lately a 28 ton bulk sample mined out from this part of Main vein exposed on surface and at lower levels than in 1975 was also shipped to the Noranda smelter and returned 0.77 opt of gold and 6.51 opt of silver. During the last half 0f 1979, the main vein was tested at shallow depth (12 holes) with a small Winkie drill. This work tested the zone to a depth of 22m below surface and a long strike from 22.8m west to 9.2 m east of shaft. Of 4 holes drilled under this part of which was bulk sampled, hole No.14 returned 0.43 opt along a core length of 2.34 m, hole No. 13, 0.12 opt/ 1.89m or 0.31 opt / 0.52m, hole No.4, 0.19 opt / 0.64m and hole No.5 drilled under hole 4 was drilled short and did not intersect the zone.

Mercier Vein
The Mercier vein (15.2-61cm) is found 183m northeast of the Main vein and consists of white quartz in silicified, carbonatized and well pyritized granite at least 1.83m, but quartz itself carries only minor sulfide. The vein lies in granite, strikes N70W dips 80S. This vein has been explored by one large trench, a 1.83m x 6.1m shaft sunk to depth of 4.87m near the east end of the vein. It is reported that a composite sample along a length of 6.2m in the shaft returned 0.11 ounce gold per ton (W.N.Ingham, Quebec department of mines, 1954). Also, it is reported that quartz samples from the dump returned 0.2 and 0.3 ounce of gold per ton (J.F.B. Davis, 1958). He also reports that a sample taken from a parallel vein, 15.3m to the north, assayed 0.428 ounce of gold per ton. In late 1979, the Mercier vein was tested by 2 holes drilled to intersect the vein below the shaft at 9.2m and 15.3m below surface. Both of holes intersected a silicified diabase dike where the vein was expected.

Third vein
The third vein is found in the No. 3 pit, 61m west of the Mercier shaft, it’s reported that quartz taken from the dump returned 0.43 opt of gold.

Fourth vein
The fourth vein is located 122m north-east of Mercier vein, no information is available of this occurrence.

Globex previous program
Both of Main vein and Mercier vein occur in fractured and sheared zones whose gouge and mud filled fractures returned spectacular gold values. Main vein strikes N58W and dips 85°N. In the shaft area, the vein turns abruptly to the south and strikes N15W and joins up with another vein parallel to the main vein (GM 36227). This strikes deviation could be linked to folding and / or faulting. Mercier vein strikes N70W dips 80S.

Both of two veins are strongly oblique (60-70°) to main north-east dike near which (<150m) quartz veins returned best assays. The north-east dike is assumed post mineralization but may consists of a drain mineralizing fluids?.

Relationship between quartz veining, dikes and shear and fractured zone is necessary to explore Main vein and Mercier vein extensions and eventual other veins in the vicinity of main north-east dike.

Before drilling campaign, Globex Mining Inc. plans EM-VLF airborne on whole of property and Mag-MaxMin survey on interesting zones completed by surface mapping and stripping.
