33 Carats


33CARATS GOLD PROJECT (BOHIER TONALITE target)
Upper Eastmain River, James Bay, Quebec
Helicopter-borne prospecting, geological mapping and soil sampling completed over the last two years by Dios delineated a highly prospective area for gold within a felsic intrusive, located at the head of a gold-in till dispersal train on wholly-owned 33 CARATS project. The 33 CARATS claims are located along
road 167 north of the town of Chibougamau, Quebec, some 40 km south of the Renard diamond deposit and 6 km northwest of the Eastmain Mine gold deposit DiosBOHIER TONALITE hosts numerous porphyry-type gold-silver-copper-bismuth showings associated with a magnetic low. The head of the gold glacial train points to the low magnetic anomaly within the BOHIER TONALITE (a 3.5 by 1.5 km area).

First gold-bearing tonalite outcrops were discovered in summer 2012. The property is cut by the Eastmain River and hosts numerous shallow lakes. It is poorly outcropping, with large areas covered by swamps, muskegs and creeks. Typical mineralization within tonalite consists of disseminated/stringer pyrite-chalcopyrite associated with 1-5% biotite-magnetite and/or quartz stringers /veinlets.

With Fall 2013 first road access, a first drill program was undertaken to locate the source of some mineralized boulder trains and to drill-test some surface showings within the BOHIER TONALITE on dry ground accessible from the road. A total of nine exploratory diamond drill holes totalling 1332 m were completed on the BOHIER TONALITE. The drill program specifically targeted weak to high magnetic lineaments within the magnetic low.

Drilling was divided into two parts, with a two km area between the two remaining untested due to lack of access, focusing first on the northern part of the low magnetic anomaly within BOHIER TONALITE, where 10 metric intervals greater than 0.100 g/t gold were intersected in three different holes: 13-01, 03 & 04. Best cut returned 1.14 g/t gold, 2 g/t Ag & 0.12% Cu over 3 m (210.35-204.35 m) in hole 13-01. Wide potassic (biotite- potassic feldspars) and propylitic (epidote-calcite) alteration zones were intersected in holes 13-01 & 03. The second part of the drill program targeted the Shower Cap area some two kilometers to the south, located at the southern limit of the low magnetic anomaly. Hole 13-07 was drilled directly underneath the Shower Cap showing to a total depth of 111 m and returned 3 intervals greater than 1 g/t gold: 1.38 g/t gold, 1.7 g/t Ag & 0.15% Cu over 0.5 m (19-19.50 m), 1.09 g/t gold, 1.2 g/t Ag & 0.13% Cu over 1.5 m (25.25-26.75 m) and 1.3 g/t gold over 1 m (100-101 m).
Best results from drill program are as follows:
--1.14 g/t gold; 2.0 g/t Ag; 0.124% Cu; 25 g/t bismuth (“Bi”)/ 3 meters (hole 13-01; 201,35-204,35 m);
--0.322 g/t gold /7.75 m (hole 13-07; 19,00-26,75 m) including 1.375 g/t gold; 1.7 g/t Ag; 0.15%Cu/0.50 m (19,00-19,50 m), 1.085 g/t gold; 0.87 g/t Ag; 0.09% Cu/1.50 m (25,25-26,75 m) and 1.295g/t gold /1 meter (100-101m).
--0.184 g/t gold /11 meters (hole 13-04; 91,50-102,50 m) including 0.97 g/t gold/ 1 meter (91,50-92,50m) and 0.868 g/t gold / 1 meter (101,50-102,50 m).

They are all associated with biotitized-silicified-sulfurized (cpy-py) tonalitic zones adjacent to feldspar-phyric intermediate dikes. Extensive porphyry-type alteration zones were observed within the tonalite. Biotitization (potassic alteration) is particularly well-developed and appears to be coincidental with a 2000 x 250 meter moderate magnetic (vertical gradient) lineament within the non to weakly magnetic tonalite (3500 x 1500-2000 m). The magnetic biotite-alteration consists of 10-30% disseminated (mm-cm) and/or fractured-filling. Potassic feldspar alteration, hematitization-epidotization, and +/-carbonation (propylitic alteration) zones are also present in the northern portion of the weakly magnetic tonalite.
The BOHIER TONALITE hosts numerous showings associated with porphyry-type mineralization in outcrops (up to 4.93 g/t gold, 6.8 g/t Ag & 0.477% Cu) and in metric boulders (up to 7.76 g/t gold, 15.7 g/t Ag, 2% Cu and 74 g/t Bi). A two km long area within the heart of the magnetic low could not be drill tested this fall. During the campaign, further prospecting & geological mapping was conducted near drill sites. Some 100 m west of Shower Cap, a metric tonalite boulder returned this year 7.63 g/t gold, 16.5 g/t Ag, 0.64% Cu & 72 g/t Bi. Some 500 m west of Shower Cap, another similar mineralized boulder (found in 2012) returned 6.11 g/t gold, 3.7 g/t Ag, 0.35% Cu. Mineralization comprises disseminated traces-1% PY-CPY-MC associated with 2% (mm up to 4 cm wide) quartz veins, hosted within a moderately silicified non-magnetic tonalite. The presence of these boulders indicates that a 500 x 500 m area located north of Shower Cap between drill holes 13-07 & 13-08 remains highly prospective. The whole area is non-outcropping and covered with swamps.

About 100 m south of drill holes 13-01 & 02, a metric boulder returned this year 5.62 g/t gold, 7.3g/t Ag, 1.48% Cu, 4g/t Bi & 94 ppm Mo within a silicified tonalite. The source of this boulder is under a swampy area that was not tested during the 2013 drill campaign because of the field conditions. Another metric boulder located approximately 350 m south graded 7.33 g/t gold, 14.5 g/t Ag, 0.63% Cu & 74 g/t Bi. Mineralization consisting of 5-15% PY-PO and tr-1% CPY-MC occurs within a sheared, strongly biotitized and magnetic zone located at the contact with a fine to medium grained feldspar phyric intermediate intrusive (dike?). The source of this boulder remains unknown. From 37 new rock samples, best results follow:

Future drilling top priority-targets include:

  • Eastern contact between tonalite and granodiorite marked by a N-S moderate magnetic lineament (gradient) located up-ice of mineralized (5.62; 6.59 and 7.33 g/t gold) tonalite glacial boulders; some weak humus gold anomalies (98,5 percentils) are present.
  •  Intersection of dioritic breccia (only observed as abundant metric glacial boulders) with E-W magnetic lineament;
  • Up-ice area of JD glacial float train (grading up to 3.18 g/t gold) intersecting the same E-W magnetic lineament associated with diorite breccia;
  • Western N-S oriented contact between the main magnetic and non-magnetic tonalite; numerous humus copper anomalies (98,5 percentil) are coincidental with the contact; including 131 000 ppb Cu.
  • Possible extent of the northern biotite-alteration zone and its intersection with the magnetic tonalite (top priority target, coincident with spectrometric potassic anomaly).

Future work includes completing a grid and geophysical induced-polarization survey on the northern portion of the weakly magnetic tonalite where holes 1 to 6 intersected more intense alterations associated with disseminated sulphides (pyrite-chalcopyrite) and magnetite. Coincidental i.p. (induced polarization)
conductors with magnetic lineaments will define priority drill targets. The E-W magnetic lineament associated with dioritic breccia and mineralized tonalitic floats also warrant being test-drilled.
Whole rock analysis and geological studies completed this winter indicate the BOHIER TONALITE belongs to the high silica leucotonalite suite (calk-alkaline) associated with a deformation zone, alteration and mineralization. Major and trace elements suggest geochemistry and geology (apart from thorium) similar to
that of the Mooshla pluton in Abitibi (which is spatially associated with five gold deposits).
The length and significant values of the gold glacial train leading to the auriferous BOHIER TONALITE are comparable to the Au33 West gold glacial dispersal train and another major gold train of the James Bay area, such is suggested from internal and proprietary data from Dios. The geological team at Dios is of the opinion that the source of such a major long gold train with many values above 2 g/t gold a above 1 g/t gold in till (heavy mineral concentrates) suggests a very significant gold source.
