Murray Brook Minerals Inc. and its subsidiary Coriolis Copper Inc. Present the Progress Report on the Legacy Copper Silver Property and the Gold McKenzie Gulch Property
A NEW EXTENSION OF THE BATHURST MINING CAMP ?
STE. ELISABETH D'AUTRAY, QC, Oct. 31, 2013 /CNW Telbec/ - Murray Brook Minerals Inc. ("MBM") and its subsidiary Coriolis Copper Inc. ("CCI") are extremely pleased to announce that the Corporations have now received all the assays from their 2013 summer drilling of the four twin diamond drill holes bored on the Legacy Copper-Silver Deposit, Restigouche Township, New Brunswick, Canada.
Dr. Christian Derosier, P. Geo., MBM's Consulting Geologist and Qualified Person for the Legacy, McKenzie Gulch and Burntland Lake Projects reports that the holes were set up close to previously drilled historic holes in order to confirm the geological and mineralogical context as well as the thickness and grade of the mineralisation intersected in the past. This twinning also will permit the geological team to qualify the previous non-compliant NI 43-101 resources calculated by Copperfields Mining Corporation Limited in 1970.
As MBM progresses at Legacy, these historic resources will then be classified as Indicated and Measured Mineral Resources with a NI 43-101 Resources Calculation Technical Report presently under review.
The first drill hole MBL-13-01 is not a twinning one of the previous hole. It was located in such a manner as to verify the mineralizations intersected by holes R-25, R-22, R-05, R-06, R-07 and R-20 bored in 1970 with different azimuths, as well as those found on surface by the old excavations.
Based on a previous structural interpretation made in 1997 that indicated that the dip of sedimentary formations and mineralized zones was abrupt to the West, it was decided to bore MBL-13-01 in opposition with holes R-05 and R-06 which are relatively short.
Results of MBM drill hole MBL-13-01 are listed below:
|TABLE No 1|
The hole was stopped in the mineralization due to a technical problem with the drill rods. Other mineralized zones were expected between 58.65 m and 75 m. Assay results are very similar to those obtained in the previous drill holes.
The second MBM drill hole MBL-13-02 was set up at 56 m North, close to Copperfields's historic drill hole R-14. In this instance, Copperfields's historic tubage was found and recorded. Drill hole MBL-13-02 was stopped at 111 m while the Copperfields's drill hole was 106.07 m long.
Intersected rocks and mineralized zones are identical to those described in holes R-14 and R-16.
Drill Hole MBL-13-02 comprises five mineralized zones.
|TABLE No 2|
In this hole, silver values were highly associated to the presence of pyrrhotite. Intersected rocks and mineralized zones are identical to those described in holes R-14 and in R-16 and R-30, bored below R-14. Its twin hole (R-14) had intersected two mineralized zones that had returned the following results:
Zone No 1: 0.93% Cu and 5.92 g/T Ag over 4.14 m;
Zone No 2: 2.38% Cu and 14.01 g/T Ag over 7.26 m.
Drill Hole R-16 bored under Hole R-14 and consequently below MBL-13-02 intersected two mineralized zones of which the first one corresponds to the MBL-13-02 zones.
Zone No 1: 1.74% Cu and 10.21 g/T Ag over 31.06 m;
Zone No 2: 0.94% Cu and 3.58 g/T Ag over 5.21 m.
Drill hole MBL-13-03 is located at 3 m South of hole R-31, at approximately in the middle of the known Legacy deposit. In 1970, Drill Hole R-31 was bored with the AXT standard core size (27 mm Ø), subject to considerable lateral and vertical deviations.
Drill Hole MBL-13-03 intersected:
|TABLE No 3|
In addition, three isolated silver values were obtained:
From 194.00 m to 195.00 m: 12.50 g/T Ag over 1.00 m;
From 211.00 m to 212.00 m: 13.00 g/T Ag over 1.00 m;
From 252.00 m to 253.34 m: 10.20 g/T Ag over 1.34 m in a skarn.
Drill Hole MBL-13-04 was set- up at 3 m South of the casing of hole S-78-01. This hole was bored in 1978, with a BQ core size (36.4 mm) and therefore was supposed to less deviate than the previous AXT equipment. Apparently, it was not the case. It totally missed the silicified rocks and the copper-silver mineralization.
Hole S-77-05, bored from a drill site located 25 m more to the West and 10-12 m lower, intersected from 343.14 m, two mineralized zones which returned the following values:
Zone No 1: 0.33% Cu and 4.22 g/T Ag over 68.34 m;
Zone No 2: 0.97% Cu and 11.23 g/T Ag over 20.02 m.
Drill Hole MBL- 13-04 is 411.00 m long and started with a dip of -65˚ and the same azimuth than S-78-01. It has been extended by 31 m because it was still in a mineralized zone at 385 m.
Drill Hole MBL-13-04 intersected:
|TABLE No 4|
The two combined zones give the following averages: 0.41% Cu and 12.99 g/T Ag over 17.46 m. This hole adds a substantial economic potential to the Legacy deposit and shows that the mineralization can be present upwards.
In addition to the drilling program, MBM is pleased to release the results of its trenching program, which was executed in July 2013. An hydraulic shovel was used to dig three trenches totalling 135 m in length. The trenching results confirmed the old work done on the Legacy property giving highgrade malachte, bornite and chalcopyrite values as well as high silver values. These trenches will enhance the mineralized content of the property close to surface.
Confirmation of a gold discovery on the Mckenzie Gulch property.
More recently, Dr. Derosier started to digitalize the old drill holes bored in the McKenzie Gulch property. He was highly surprised by the results of drill hole MC-92-20 bored in March 1992 by Noranda Exploration on the west bank of the creek, on the other side of the McKenzie Gulch Fault. According to the regional geological map, the rock extending on the west bank of the creek are related to the Boland Brook Formation. However, according to Gower and Walker (1993), the White Head Formation would extend for about 1000 m west of the McKenzie Gulch.
Hole MC-92-20 intersected from 14.50 m to 49.00 m a silicified limestone. The rocks described by the NOREX's geologist are totally similar to the Legacy Copper-Silver Deposit. Numerous quartz-carbonate-sulfides veinlets and stringers were injected in the silicified rock. Sulfides comprise pyrite, arsenopyrite, chalcopyrite and sphalerite.
From 41.46 m to 49.00 m, several one metre long samples gave the
From 41.46 m to 42.00 m: 1.03 g/T Au, 4.11 g/T Ag and 0.07% Cu over 0.54 m;
From 42.00 m to 43.00 m: 2.40 g/T Au, 4.46 g/T Ag and 0.06% Cu over 1.00 m;
From 43.00 m to 44.00 m: 1.37 g/T Au, 1.37 g/T Ag and 0.08% Cu over 1.00 m;
From 44.00 m to 45.00 m: 0.17 g/T Au, 1.37 g/T Ag and 0.05% Cu over 1.00 m;
From 45.00 m to 46.00 m: 13.71 g/T Au, 7.20 g/T Ag and 0.16% Cu over 1.00 m;
From 46.00 m to 47.00 m: 0.17 g/T Au, 19.54 g/T Ag and 1.17% Cu over 1.00 m
From 47.00 m to 48.00 m: 0.17 g/T Au, 1.37 g/T Ag and 0.06% Cu over 1.00 m;
From 48.00 m to 49.00 m: 1.20 g/T Au, 1.03 g/T Ag and 0.07% Cu over 1.00m.
Deeper, in a silicified argillaceous limestone, quartz- carbonate -sulfides veinlets gave 0.17 g/T Au, 4.11 g/T Ag and 0.23% Cu over 1.00m from 49.00 m to 50.00 m.
This hole, located at about 850 m NNW of the Legacy Deposit opens a new area for an aggressive exploration program.
In order to better cover the North extension of those mineralization, six new claims have been added to the McKenzie Gulch Project.
The target is now to confirm the extension at depth, to the southwest and to the northeast of the mineralized zones and to fill some gaps in the previous drilling pattern. A minimum of 10 000 metres of drilling have been planned for this purpose. The holes will allow the increase of the tonnage of the historic mineral resources and will bring a large part of them to Measured Mineral Resource category on both Legacy and McKenzie Gulch properties.
This press release has been reviewed by Dr. Christian Derosier, P. Geo., Consulting Geologist and Qualified Person for the Legacy, Burntland and McKenzie Gulch Projects under National Instrument NI 43-101.
Murray Brook Minerals Inc., a privately owned mining exploration and development company, recently transferred to its subsidiary, Coriolis Copper Inc., 100% of the Legacy Deposit and the Burntland Project.
