Copper Reef to Drill Massive Sulphide Targets in Flin Flon

February 28, 2019

Copper Reef Mining Corporation (CSE: CZC) (the "Company") is pleased to announce the beginning of their Base Metal Drilling north of Sourdough Bay in the main Flin Flon Camp of Northern Manitoba. The Company plans to drill initially 2 to 3 targets of 7 Airborne VTEM targets that occur just north of the former Pine Bay, Baker Patton and North Star Mines. The three being drilled occur as a cluster of four, possibly representing mineralization connected at depth (Ross Groom -VTEM Modelling Report's 2018 and 2019) over a combined strike length of 300 m. Individually targets vary from 80 to 150 m in strike length.

The target area lies along a felsic volcanic fragmental contact with mafic lapilli tuff-tuff breccias. The underlying felsic rocks are extremely altered with little or no calcium and sodium typical of extreme VMS alteration. The felsic volcanic rocks along this horizon as mapped to the north are "F3" rhyolite; considered productive rhyolites to host volcanogenic massive sulphide (VMS) mineralization. The target horizon was only observed in outcrop 2 km north of the main cluster where it is represented by a 10-12 m wide zone of gossanous pyritic cherty exhalite type sediments.

The most northern target of this cluster and the one which will be drilled first is the VTEM Anomaly Z2-4. It is considered an "A" class VTEM target intersected on two flight lines (an E-W line and a NNE flight line). The target was originally covered with Horizontal Loop EM (HLEM) ground geophysics in 1980 by Granges following up an Areodat Airborne Anomaly. The HLEM had 300 ft. spacing's between coils basically seeing as deep as half that spacing (150 ft. or 46 m). The HLEM survey produced a distinct well defined anomaly. A drill hole (DDH AM-1) into the anomaly return zinc and silver mineralization with minor copper; but all mainly stringer mineralization with no significant massive sulphide intercepts. The later airborne survey by VTEM indicated little mineralization in the top 100m but with a significant conductor at depth. Copper Reef will retest this anomaly which appears to consist of two plates: a shallow weaker conductor and a much stronger deeper conductor with a single hole AM-19-6. The weaker anomaly will be intersected 40 m below the previous drill intercept while the deep conductor is planned to be intercepted between 130 and 160 m down hole or 120 m vertically drilled at -62 degrees with a 270 azimuth. The conductors appear to be dipping steeply at -85 to the east.

VTEM Airborne Anomaly Z2-5 occurs 100 m south of Z2-4 and appears to be on strike. This is also a moderate anomaly near surface but with a deep conductor at depth. The VTEM Airborne conductor occurs in the middle of two E-W and two NNE flight lines, so its location is fairly well defined. This anomaly was also surveyed with HLEM at 300 foot spacing by Granges and produced a fairly good anomaly despite being beneath a swamp. Granges's attempt to drill (DDH AM-2) this conductor failed as the drill hole overshot the conductor due to depth of the cover (70 feet) causing them to miss the target. Z2-5 appears to be only represented by a single conductive plate which is weak near surface (down to 70 m) but quite strongly conductive at depth below 120 m vertically. Copper Reef's planned drill hole AM-19-7 is aimed to intersect this anomaly at 150 m vertically. There is some indication of conductors east of this plate but because they are deep; they are at the vertical limit of the VTEM survey data to properly access. The planned hole, however is set back far enough to cover most of the favourable stratigraphy. Diamond Drill Hole AM-19-7 will be drilled at -65 with an azimuth of 270 degrees. This conductor target also dips steeply (-85 degrees) to the east.

VTEM Airborne Anomaly Target Z3-1 occurs 200 m south of Target Z2-5. This is a moderate conductor but deep (>105 m) and not well represented by Granges's HLEM ground survey which barely saw the anomaly due to the depth and their short cable. Granges's attempt to drill (DDH AM-4) the target either stopped short or went above the conductor as little mineralization was encountered in the drill hole. Copper Reef's planned drill hole AM-19-8 is planned to intersect the conductor at 175 m at a vertical depth of 125 m. The drill hole will be drilled a -45 degrees and at an azimuth of 300 degrees. Ross Groom likes this target the best because of its good conductance with depth and that it flanks a strong magnetic feature located between VTEM Airborne anomalies Z3-1 and Z3-2 both deep targets.

The Property is easily accessible via the North Star Mine Road off of old highway 10 south of Flin Flon. An existing main drill road (2 km) leads to the target areas where old subsidiary drill roads provide access to drill set ups. Work permits are in place. Ploughing of snow along these access roads and drill site preparation has begun. Ross Industries Ltd will be providing access to the sites and ensuring these activities are carried out safely and in accord with environmental laws and conditions of the work permit. Copper Reef is the only company carrying out exploration drilling in the main Mining Camp of Flin Flon of Manitoba where the Company has a large property package and many remaining high quality VMS and gold targets and deposits.


Copper Reef is a Canadian junior mineral exploration company with a specific focus on mineral properties in Northwest Manitoba and Northeast Saskatchewan, Canada. All of the Issuer's properties are currently at the exploration stage. The Company has assembled a portfolio of base metal and precious metal prospects including strategic locations in the Provinces of Manitoba and Saskatchewan, all of which are 100 percent owned with no option payments or work commitments to a third party.
