MIDLAND DISCOVERS A NEW HIGH-GRADE COPPER-GOLD-MOLYBDENUM-SILVER MINERALIZED SYSTEM OF AT LEAST 700 METERS STRIKE LENGTH ON THE MYTHRIL PROJECT IN JAMES BAY

Midland Exploration Inc. has made a recent discovery of a copper-molybdenum-gold-silver system at its wholly owned Mythril (formerly Lothlorien) project in James Bay, Que. The Cu-Au-Mo-Ag mineralized system is at least 700 metres long on surface, oriented east-west and is open in both directions. The mineralized system is interpreted based on outcrops and locally sourced, angular float fields. It is interpreted to be of the Cu-Au-Mo porphyry type. The full dimensions of the mineralization are not known yet.

Highlights:

  • Cu-Au-Mo-Ag mineralized system interpreted over 700 metres, open east and west.
  • Fifty-four new high-grade Cu-Au-Mo-Ag mineralized floats; average values of 2.61 per cent Cu, 1.25 grams per tonne Au, 0.13 per cent Mo and 28.7 g/t Ag over the 54 floats (grab samples); maximum values of: 13.2 per cent Cu; 16.8 g/t Au; 0.58 per cent Mo; 112 g/t Ag. Float are concentrated in five major fields. Most of the float are angular and are interpreted to be locally derived (less than 100 m transport distance).
  • Channel result of 2.74 per cent Cu, 0.44 g/t Au, 0.06 per cent Mo and 24.3 g/t Ag over 2.7 metres, including 4.52 per cent Cu, 0.65 g/t Au, 0.1 per cent Mo and 40.1 g/t Ag over 1.5 metres on the Celeborn showing. Mineralization open in all directions.
  • New Arwen Cu-Au-Mo-Ag mineralized float field, that returned high-grade gold values, with up to 16.8 g/t Au. It is the easternmost float field.
  • New Legolas showing with grab sample of 4.89 per cent Cu, 1.5 g/t Au and 46 g/t Ag.

The attached tables summarize the results of channels and of the main float fields found on the mineralized trend.

The Mythril project is located about seven kilometres south of the Trans-Taiga road, James Bay Eeyou Istchee, Quebec. The project was initiated in June/July, 2018, following the discovery of three Cu-Au-Mo-Ag showings, found over 225 metres laterally. The Galadriel showing had returned up to 4.3 g/t Au; 7.19 per cent Cu; 0.45 per cent Mo; 61.9 g/t Ag in grab samples. The Celeborn showing had returned up to 0.95 per cent Cu, 0.66 g/t Au and 21.2 g/t Ag in grab samples from three locally sourced float. The 76 showing had returned 0.66 per cent Cu, 1.0 g/t Au and 15.4 g/t Ag. Only half a day of prospecting was spent on the project in June. Exploration in September consisted in additional prospecting, as well as manual trenching and channel sampling of the showings.

Descriptions of showings and float fields

The Celeborn showing was manually stripped and exposed on a 2.7-metre-by-2.5-metre area. A single channel performed on the trench yielded 2.74 per cent Cu, 0.44 g/t Au, 0.06 per cent Mo and 24.3 g/t Ag over 2.7 metres, including 4.52 per cent Cu, 0.66 g/t Au, 0.1 per cent Mo and 40.1 g/t Ag over 1.5 metres. Mineralization at Celeborn is open in all directions, in thickness (north-south) as well as laterally (east-west), under surficial deposits. Twenty-two locally sourced mineralized float were found in a 25-metre radius around the showing. They yielded up to: 13.2 per cent Cu; 2.92 g/t Au; 0.58 per cent Mo; 112 g/t Ag in grab samples; the average grade of the 22 float is 4.2 per cent Cu, 0.95 g/t Au, 0.19 per cent Mo and 40.9 g/t Ag. Mineralization in the trench and float mainly occurs as disseminated chalcopyrite and molybdenite in paragneisses that exhibit strong potassic alteration and/or silicification. Semi-massive chalcopyrite clusters are also found in felsic intrusions; quartz-chalcopyrite veins are also found in the paragneisses.

The Galadriel showing is located about 150 metres east of Celeborn. It was manually trenched over a 12-metre-by-3.5-metre zone. Mineralization occurs in its eastern part as a semi-massive chalcopyrite zone found in a felsic dike and in the surrounding paragneiss, strongly affected by potassic alteration. Channel R2 returned 0.64 per cent Cu, 0.13 g/t Au, 0.04 per cent Mo and 5.49 g/t Ag over 1.5 metres, while channel R1 yielded 6.34 per cent Cu, 0.78 g/t Au, 0.23 per cent Mo and 49.4 g/t Ag over 0.25 metre. In its western part, the mineralized zone becomes larger and more disseminated and returned 0.60 per cent Cu, 0.28 g/t Au, 0.03 per cent Mo and 5.8 g/t Ag over 2.5 metres in channel R3 and 0.55 per cent Cu, 0.26 g/t Au, 0.25 per cent Mo and 5.39 g/t Ag over 3.3 metres in channel R4, mainly in the paragneiss with strong potassic alteration. Mineralization in channels R3 and R4 is open to the south. The Galadriel showing remains open east and west.

The Legolas showing is located about 160 metres west of Celeborn, and more than 300 metres west of Galadriel. The showing consists in two grab samples of paragneisses with disseminated to semi-massive chalcopyrite, collected on a two-metre-by-one-metre trench, that yielded 4.89 per cent Cu, 1.5 g/t Au and 46 g/t Ag. Six locally sourced mineralized float were also discovered a few metres from the showing. These floats have yielded up to: 5.13 per cent Cu; 1.22 g/t Au; 0.26 per cent Mo; 38 g/t Ag in grab samples, with an average of 2.28 per cent Cu, 0.81 g/t Au, 0.11 per cent Mo and 20.8 g/t Ag for the six floats. The float are biotite-paragneisses with disseminated or stringers of chalcopyrite, as well as felsic intrusives that are strongly mineralized in semi-massive chalcopyrite.

The Arwen float field is located 250 metres east of Galadriel. In this area, a series of nine locally sourced float of biotite-paragneiss, containing disseminated to semi-massive chalcopyrite were found. The nine floats yielded an average of 1.13 per cent Cu, 3.5 g/t Au, 0.06 per cent Mo and 22.4 g/t Ag in grab samples. The Arwen float field appear to carry locally high gold grades, with two float yielded high gold grades of 16.8 g/t Au and 9.09 g/t Au in grab samples. The Arwen float field is the richest in gold and is located at the known eastern edge of the mineralized trend; the trend is still open to the east.

The Go West showing is found 250 metres west of Celeborn. It is a mineralized layer at least 50 centimetres thick with disseminated chalcopyrite-pyrite-magnetite at the bottom of a paragneiss outcrop. It was followed over 30 metres laterally. It returned 0.45 per cent Cu and 0.02 per cent Mo, as well as 0.37 per cent Cu, 0.02 per cent Mo in two grab samples. A locally sourced paragneiss float located at the bottom of the outcrop also yielded 1.87 per cent Cu, 0.65 g/t Au 0.25 per cent Mo and 20 g/t Ag in a grab sample.

A field of seven float of paragneisses and felsic intrusives mineralized in chalcopyrite and/or molybdenite was found 80 metres west of Celeborn. They yielded up to: 7.97 per cent Cu; 1.47 g/t Au; 0.56 per cent Mo; 64.3 g/t Ag in grab samples, with an average of 2.29 per cent Cu, 0.68 g/t Au, 0.11 per cent Mo and 23.7 g/t Ag for the seven floats. These floats could originate from the Celeborn showing or represent a distinct mineralized source.

Three additional biotite paragneiss float mineralized in chalcopyrite were also found more than 300 metres north-northwest of the Galadriel showing. They yielded up to: 0.88 per cent Cu; 0.64 g/t Au; 0.11 per cent Mo; 24.4 g/t Ag in grab samples. The source of these float remains unknown.

The Galadriel, Celeborn, Legolas, Go West showings and the Arwen float field form a perfectly linear trend, at least 700 metres long and open to the west and east. The association of many showings with felsic dikes of varying grain size and the copper-gold-molybdenum-bismuth-silver association suggest that the mineralization is of the porphyry copper-gold-molybdenum type. However, it has clearly been affected by amphibole-grade regional metamorphism and deformation, which has obliterated the original texture of the rock and make it more difficult to recognize the deposit type. Future geoscientific investigations will be able to refine this model.

Next phases of work

Midland is very satisfied with these significant results obtained from only four days of prospecting in September on its Mythril project. An extensive soil geochemical survey as well as additional prospecting were performed during the last weeks to better define the extent of the mineralized system. A geophysical survey (induced polarization) will be performed in fall or winter to define mechanical trenching and eventual drilling targets on this very high-potential new discovery.

Quality control

Exploration program design and interpretation of results is performed by qualified persons employing a quality assurance/quality control program consistent with industry-best practices, including the use of standards and blanks with every 20 samples. Rock samples on the project are assayed by standard 30-gram fire assaying with inductively coupled plasma atomic emission spectroscopy (ICP-AES) or gravimetric finish at ALS Minerals laboratories in Val d'Or, Que., or Sudbury, Ont. All samples are also analyzed for multielements, using four-acid ICP-AES method. Samples that exceed 1 per cent copper, zinc or nickel are reanalyzed by four-acid ICP-AES optimized for high grades.

The technical or scientific information in this press release has been prepared by Sylvain Trepanier, PGeo, vice-president of exploration for James Bay and Northern Quebec at Midland, a qualified person as defined by National Instrument 43-101.
