Botswana Molopo Farms Complex - Exploration Update

Proof-of-Concept Exploration Holes Recently Completed Confirm the Presence of Primary Magmatic Sulphides at Molopo Farms Complex Project

 

Power Metal Resources PLC (LON:POW) the AIM listed metals exploration and development company is pleased to announce an exploration update at the Kalahari Key Mineral Exploration Pty Ltd ("Kalahari Key" or "KKME") Molopo Farms Complex Project (the "Project" or "MFC Project"), which is prospective for magmatic intrusion-hosted massive and disseminated nickel-copper sulphide and platinum-group element ("PGE") mineralisation in mining friendly Botswana.

Power Metal currently has a 40% direct MFC Project interest as well as an 18% shareholding in Kalahari Key, for a combined effective economic interest of 50.8%.

Christian Schaffalitzky, Chairman of Kalahari Key, commented:

"The MFC Project is transected by the Thabazimbi-Murchison lineament ("TML"), a major fault system which trends easterly and is believed by Kalahari Key to be the same structure which controlled the emplacement of magma within the highly prolific Bushveld Igneous Complex ("BIC") located in South Africa. The BIC is one of the world's major sources of nickel and platinum group metals ("PGMs").

By extension, the TML is believed to be the feeder for the Molopo Farms Complex ("MCF"), and thus a target for a Voisey's Bay style major nickel deposit. A feeder zone structure is interpreted to be close to hole K1-6 and extends north-eastwards to the edge of the licence area.

Recently completed proof-of-concept drilling by Kalahari Key, including three widely spaced diamond drillholes targeting large-scale conductive electromagnetic ("EM") geophysics anomalies, has identified in hole K1-6 the highest nickel grades to date within the MFC. Significantly, thin section analysis of select drill intercepts has identified primary magmatic sulphide mineralisation including pentlandite and chalcopyrite.

With several targets to be followed up, the work plan is still being finalised and the priorities set."

Paul Johnson, Chief Executive Officer of Power Metal Resources plc, commented:

"The results to date from the Phase I drill programme at the MFC Project have successfully demonstrated the validity of the geological model developed by our operating partner Kalahari Key, which has led to the discovery of primary nickel-copper and PGE mineralisation.

Further technical review of the Phase I exploration results is ongoing, and we look forward to providing further information in this regard.

The aim of our venture at the MFC project is the discovery of a major nickel deposit, and we have clearly taken a number of important steps forward with recent exploration.  Now we need to finalise the technical review of the work done thus far, and implement next stage exploration work including a Phase II drill programme."

 

PROJECT BACKGROUND:

The MFC Project is a district scale exploration opportunity located in southwestern Botswana. 

After extensive preparatory exploration work conducted over the previous five years by Kalahari Key, including airborne and ground-based Electro Magnetic ("EM") surveys which identified a number of highly prospective kilometre-scale conductive targets, the Project was suitably advanced to commence proof-of-concept drilling late in 2020.

The Phase I diamond drilling commenced at the MFC Project in October 2020 with three holes completed. Due to the size of the Project and prospective conductors identified by the EM surveys, the drilling was conducted as proof-of-concept in order to determine if the conditions within the magmatic system were ideal for the formation of primary magmatic Ni-Cu sulphides, similar to those found within the Bushveld Igneous Complex located along strike to the east.

Significantly, examination of the three proof-of-concept drillholes has successfully identified a magmatic feeder zone which is prospective for the accumulation of Ni/PGE sulphides within the MFC project.

The assay results for core samples submitted from hole KKME 1-14 are outlined below. These results represent the second batch of assay results for the MCF Project and continue to build on the geological understanding of the MFC Projects magmatic feeder zones following the significant Ni-Cu intersections reported previously from drillhole KKME 1-6 (announced 8 April 2021).

DRILL RESULTS:

KKME 1-6

The assay results from angled diamond drill hole KKME 1-6 drilled to a total depth of 597.8 were previously reported on 8 April 2021 and are outlined in table 1 below. 

Four select intervals from drillhole KKME 1-6 were analysed at the Scientific Services Geological Laboratories ("SCISERV") laboratory in Cape Town, South Africa which include 292.7 - 297.5m, 308.5 - 313.2m, 501.8 - 529.1m, and 585.0 - 597.8m.

 

Significant nickel intersections  1  include:

· 4.8m @ 0.2% Ni from 292.7m

· 4.1m @ 0.49% Ni from 309m, including   1.6m @ 0.72% Ni from 309.6m

· 16.7m @ 0.16% Ni from 501.8m

· 10.9m @ 0.13% Ni from 518.2m

· 3.4m @ 0.28% Ni from 594.4m to end of hole at 597.8m (mineralisation remains open at depth)

Individual samples were also sent to the University of Witwatersrand for thin section mineralogical analysis. The results of this analysis, set out below, successfully identified the presence of primary pentlandite, secondary nickel sulphide and chalcopyrite mineralisation within three drill core samples from KKME 1-6:

· IMK-05139 (0.44m pyroxenite sample from 310m down-hole depth) assayed at 6,999ppm Ni (0.70% Ni) from a primary magmatic, pentlandite-bearing, assemblage.

· IMK-05149 (0.58m pyroxenite sample from 295m down-hole depth) assayed at 6,606ppm Ni (0.66% Ni).

· IMK-05153 (0.54m pyroxenite sample from 297m down-hole depth) assayed at 2,244ppm Ni (0.22% Ni).

· Both IMK-05149 and IMK-05153 contained primary pentlandite within predominant secondary nickel sulphides, arsenides and alloys.

 

KKME 1-14

 

The assay results from angled diamond drill hole KKME 1-14 drilled to a total depth of 515.8m are outlined in table 2 below. 

Four select intervals from drillhole KKME 1-14 were analysed at the SCISERV laboratory which include 180.0 - 188.8m, 192.2 - 201.2m, 207.9 - 208.5m and 475.4 - 483.22m.

 

Significant nickel intersections  1  include:

 

· 6.0m @ 0.17% Ni from 180.0m in harzburgite rock immediately above a fault zone at 186m; and

· 1.0m @ 0.11% Ni from 194.0m in serpentinite with a partial breccia texture within an intra-fault zone totalling 9m @ 0.07%Ni between 192m and 201m downhole.

 

The drilling intersected the ultramafic rocks of the Molopo Farms Complex directly below 40m of Kalahari sand and duricrust cover and continued to a faulted contact with Transvaal Supergroup quartzite units to a downhole depth of 205.5m. The hole remained in Transvaal rocks through to its end at 515.8m downhole depth.

The anomalous nickel mineralisation identified at shallow depths within KKME 1-14 supports the findings from hole KKME 1-6 (located over 20km away) and further demonstrates there is potential for nickel enrichment in the magmatic intrusive system. Together with the encouraging results obtained from hole KKME 1-6, the combined drill hole findings provide important geological information which will help plan a Phase II drill programme which aims to vector towards significant quantities of magmatic nickel-copper mineralisation within this fertile magmatic system.

KKME 1-14 was drilled targeting a broad kilometre-scale EM anomaly which can be traced further to the east, which is the known orientation of magmatic layering within the MFC. This same EM anomaly extends towards the west and then swings southwest into the northeast-southwest trending sheer zone which is interpreted to represent a feeder zone on the Project. As a result, Kalahari Key is of the belief that this conductive target potentially represents a much larger Ni-Cu mineralised system than originally understood.

 

NEXT EXPLORATION STEPS:

Technical work is continuing including further core inspection of the third drill hole K1-11a and assay testing of samples from this hole together with assay testing of additional samples from K1-6 where further sulphides have been identified. 

A further update will be provided in due course summarising all the technical work completed.

Notably, the technical work includes planning a Phase II drilling programme which is being designed to intersect the up-dip part of the mineralised pyroxenites identified in KKME 1-6, as well as where the east-west oriented EM anomaly intersects the magmatic feeder zone. Further information in respect of this work and associated exploration plans will be provided in due course.

Assaying Technique and Results

Scientific Services Geological Laboratories ("SCISERV") located in Cape Town, South Africa, analysed half core samples for nickel, copper, gold and platinum with the results summarised in Table 1 and 2 below.

SCISERV employed a two acid (HNO3 + HF) digest with analysis by inductively coupled plasma optical emission spectrometry ("ICP-OES").

Further Details

Hole KKME 1-14 was drilled at an azimuth of 345° with a dip of 60° to a final depth of 515.8m. The hole was designed to intercept a conductive body modelled from ground-based TDEM geophysical survey which was expected to lie at roughly 500m down-hole depth. The cause of this prospective conductor is still unknown.

Drill hole KKME 1-11a, the third and final hole of the proof-of-concept drill programme, is located in the Project's Chipo (Gift) Northern Target Area, 1,250m west of 1-14.
