Playfair Mining is a mineral exploration company based in Canada. The New RKV project in Norway has set the company in a new direction as it begins exploring for copper, cobalt and nickel in a historic base metal area of Norway.
-300 square km
-35 km north to south, 16 km east to west
-2 Past Producing Copper Mines
-1 Nickel/Copper Deposit
Progress has been rapid since March 2019 when Playfair signed an agreement to earn a 100% interest in the RKV property in South Central Norway. Data Mining and Pattern Recognition using the CARDS AI system provided 27 targets. Initial MMI geochemical surveys evaluated 24 selected CARDS targets and found 15 to have significant levels of copper, cobalt or nickel. A detailed MMI survey has been completed on one area with very favourable results. Drill testing is planned for this Winter.
A Mining Area in Mining Friendly Norway. Over 80 million tons contained in 10 large VMS copper and zinc deposits within 75 Km of the Project. The RKV Project contains 2 past producing Besshi-type VMS copper mines, a nickel-copper deposit and over 20 additional known mineral occurrences. There has been no significant exploration for copper since 1977 and no significant exploration for nickel since 2006.
According to the Norwegian Geological Survey (NGU) 388,000 tons were mined from 1908 to 1920 and100,000 were left in “reserves”. Bedrock samples taken by NGU in 1998 assayed up to 6.96% copper,0.59% zinc and 0.08% cobalt.
According to the Norwegian Geological Survey (NGU) about 250,000 tons of ore were produced between 1629 and 1789. Dump samples taken by NGU in 1998 assayed up to 3.14% copper,6.35% zinc and 0.06% cobalt.
A (non 43-101 compliant) resource of 400,000 tons of 1.0% nickel and 0.4% copper was calculated by Falconbridge Nickel Mines in 1977 based on 109 core holes drilled between 1975 and 1977.
A large amount of data, including high-quality helicopterborne geophysical surveys, was available on-line from the Norwegian Geological Survey (NGU). There are many showings (all sampled and assayed by NGU) and many geophysical anomalies. There are several geological causes for electromagnetic anomalies other than orebodies. Barren sulphides and graphite are the most common and both occur throughout this area. The orebodies are usually magnetic but there are also other geological causes of magnetic anomalies. Barren pyrrhotite is one, rock units such as iron formation and mafic volcanic rocks are others. All are common in this area.
-RKV Project: The Challenge.
The plethora of extensive airborne geophysical anomalies presents a real challenge to explorers. There are too many anomalies to thoroughly explore all of them yet there may well be unknown ore deposits concealed within the noise.
An explorer who overcomes the challenge to sort the worthwhile targets from the worthless noise has a real opportunity to discover valuable new deposits.
Playfair developed a plan to use a two-stage screening method. The first stage: Artificial Intelligence and pattern recognition algorithms to generate targets. The second stage: evaluate the targets by modern geochemical methods.
First Stage – CARDS AI:
Windfall Geotek was contracted to apply its proprietary CARDS AI (Computer-Aided Resources Detection System) to the project. A geo-referenced database was compiled from the large existing amount of geological and geophysical data available from the Geological Survey of Norway (NGU) covering the project area. The project was divided into 180,720 datapoints (40 by 40 metre cells). A total of 414 variables comprising primary, derivative and neighbouring variables was used for each datapoint. Two models were built: a VMS Cu - Zn model that included 39 Positive Cu - Zn Training Points (Cu or Zn above 5000 ppm and a magmatic Ni - Cu model that included 80 Positive Ni - Cu Training Points (Ni or Cu above 5000 ppm).. Complex algorithms were then generated to describe the characteristics of the Positive Training Points and these algorithms were then used to evaluate all cells for similarity to the Positive Training Points for each model.
-RKV Project: Second Stage – MMI Geochemistry:
Mobile metal ions are released from oxidizing mineralized material and travel upward through overburden toward the surface. Using careful soil sampling strategies, sophisticated chemical ligands and ultrasensitive instrumentation, SGS can measure these ions. Target elements are extracted using weak solutions of organic and inorganic compounds rather than conventional aggressive acid or cyanide-based digests. MMI solutions contain strong ligands, which detach and hold metal ions that were loosely bound to soil particles by weak atomic forces in aqueous solution. This extraction does not dissolve the bound forms of the metal ions. There are many benefits to using MMI technology for soil geochemistry: Focused, sharp anomalies with excellent repeatability. Low background values (low noise) with few false anomalies. Low limits of detection. Mobile Metal Ion samples are easy to take, sample material can be any mineral soil and no specific knowledge of sample material or stratigraphy is needed.
-RKV Project: Initial MMI Sampling
Sampling grids were laid out on 24 selected CARDS targets. Sample lines were 100 metres apart with samples every 25 metres. A total of 1,050 samples were collected in less than one month. Samples were analyzed for 53 elements by SGS using MMI extraction and ICP.
-.RKV Project: Significant results from Initial MMI:
43 significant samples in 15 grids with values over 50 times background in one or more of copper, nickel or cobalt. Including 14 very significant samples in 8 grids with values over 100 times background in one or more of copper, nickel or cobalt. Also including 7 highly significant samples in 3 grids with values over 200 times background in one or more of copper, nickel or cobalt.
-RKV Project: Initial MMI Results Grids VMS-16, 17, 18 and 19:
SGS MMI Short Report states: There are 14 values for MMI Cu>6000ppb in this area; Many if not all of these are likely to be associated with weathering copper sulphides; The highest is in sample VMS18-779; 48400ppb at 569574E, 6911363N; This is one of the highest recorded values of MMI Cu in a soil; 6000 ppb MMI Cu is 44 times background.
-RKV Project: Initial MMI Results Grid VMS-18:
The highest MMI Cu value from RKV is 48,400 ppb MMI Cu. This is among the highest ever recorded values for MMI Cu in a soil and the highest Significant MMI Cu responses in over 200 metres. There is no record of any mineral exploration in this area.
-RKV Project: Storboren Copper Anomaly MMI Follow-Up:
Detailed closely spaced samples were taken around the very high MMI Cu values on Grid VMS-18. MMI sampling was extended to the Southeast. The Storboren Copper Anomaly is now shown to be at least 200m long and 75m wide. The anomaly is open to both the Northwest and Southeast. This is a prime drill target.
-RKV Project: Storboren Copper Anomaly
The MMI Cu values are consistently high over an area of at least 200 m by 75 m. The Anomaly is open to both the Southeast and Northwest. According to SGS: These are among the highest ever recorded values for MMI Cu in a soil. Many, if not all, values for MMI Cu over 6000ppb are likely to be associated with weathering copper sulphides.
-Location, Access & Infrastructure:
The property is located adjacent to the fishing village of Grey River (population of ~ 350 people) on the south coast of Newfoundland. Grey River is serviced daily by coastal boat from Burgeo, a coastal port about 40 km to the west. Burgeo is linked by a highway to the Trans Canada Highway and the airport town of Stephenville approximately 125 km to the north. The claims are accessed by foot and helicopter while the Main Zone adit is within 150 metres by gravel trail from Grey River village. A local diesel supplies electricity to Grey River. A large government owned wharf exists in Grey River.
A 6,300 foot long (1,920 metre) adit has been driven into the Main Vein from near the village of Grey River at approximately 40 metres above sea level. Docking and wharf facilities existed at the Asarco adit but the present conditions are not known.
-Property & Ownership:
The property consists of nine mineral claims (1,750 hectares) that were map staked on August 24, 2000 and July 10, 2001. The claims, were acquired from South Coast Ventures by Playfair Mining (100%). The property is covered on claim map sheet NTS 11P/11.
Tungsten mineralization was first noted near Grey River around 1956. Subsequent exploration by Asarco during 1957 to 1970 included surface geological mapping, trenching and diamond drilling on five of the better veins, driving a 6,300 foot long exploration adit into and along the Main (#10) vein, driving 20 short raises into the vein and collecting a 275 ton bulk sample for a number of metallurgical tests by Asarco and CanMet. Asarco had destined the project for production around 1970 but the drop in tungsten prices shelved the project. The property changed hands several times but no further work was done from 1970 to present day. The claims expired in June 2000 and were map staked by South Coast Ventures when the Newfoundland government released the ground for staking.
The immediate area is underlain by Ordovician-Silurian age metasedimentary amphibolites and quartz-mica schists and gneisses that predominate to the north. Bedding and foliation-banding strike E-W and dip steeply north. Extensive granitic rocks predominate north of the metasedimentary units. Pegmatites cut all rocks and can form considerable amounts locally. Three prominent fault sets occur; an E-W set is the strongest and brings metasedimentary rocks into contact (usually mylonitic) with the granitic rocks. A younger north to NE trending fault set is commonly occupied by quartz veins hosting the tungsten mineralization.
The Grey River tungsten veins are typical fluorite-rich wolframite-quartz greisen vein deposits. Most of the tungsten mineralization is wolframite with a number of small scheelite occurrences known. GSC Economic Geology Report 32 (Geology of Canadian Tungsten Occurrences, R. Mulligan, 1984) lists the Grey River deposits as “one of the largest typical wolframite deposits in Canada” and states “in view of the geological environment and the presence of beryllium, molybdenum, fluorite and base metal deposits, it would be remarkable if there were not many more tungsten occurrences’ (on the property).
The wolframite veins occur mainly in the metamorphic rocks but also in the granitic rocks to the north. Over 300 veins and lenses have been mapped on surface although to date only two or three appear significant enough to have been partially evaluated by Asarco. The Main (#10) Vein is from 0.9 to over 4.3 m wide and averages ~1.2 m wide (based on underground mapping) and has been traced for over 1,600 m long with the #10 ore shoot over 775m long. Over 240 m vertical thickness is defined above the adit. The vein increases in width with depth and appears to also increase in grade with depth. Tungsten grades substantially increase with face sampling and bulk sampling compared to drill hole grades; this is likely a result of poor drill core recoveries but is also due to a significant ‘nugget effect.’.
Resources & Potential: In March of 2011, Playfair reported an updated NI 43-101 Compliant Mineral Resource Estimate completed by Desautels Geoscience Ltd. (“DGL”) of 18.8 million pounds of Inferred Resource (1,169,000 tonnes at an average grade of 0.730% WO3 at a 0.20% WO3 cut-off). The resources show an overall increase of 16% in contained tungsten over the 2007 estimate of 852,000 tonnes at an average grade of 0.86% WO3 containing 16.2 million pounds of tungsten trioxide.
- Ox Mountain, Republic of Ireland
We are targeting a deposit similar to Dalradian Resources Curraghinalt deposit.
Ireland was ranked #1 out of 122 jurisdictions in overall mining policy attractiveness by the Fraser Institute in 2013, 2014, 2015 and 2016. Ireland is the largest zinc producer in Europe and the second largest producer of lead.
Bowpark is a private Irish Company owned by geologists Andy BOWden and Rick PARKER. Bowpark obtained 16 Prospecting Licences covering 679 square Km of Dalradian rocks near major structures in the Ox Mountains Prospecting of the 16 licences found 2 previously unknown areas of angular blocks of “float” containing gold The property was then reduced to 3 licences covering 139 square Km.
Before Playfair, Bowpark’s initial prospecting discovered two previously unknown areas with angular, locally derived blocks containing significant gold.
-Playfair Bowpark Agreement:
Playfair and Bowpark signed an option agreement in November 2013 following Bowpark’s initial prospecting whereby Playfair can acquire up to 100 % of Bowpark.
Playfair may, over time in 4 tranches, acquire a 90% interest in Bowpark by expending $2,280,000 directly on exploration and delivering 1,800,000 shares of Playfair to the current owners of Bowpark with provisions to acquire the remaining 10%.
Playfair funded Bowpark to carry out follow-up detailed prospecting and soil geochemistry at both Cloonacool and Cabragh. The area of gold-bearing locally-derived angular blocks (“float) was increased, higher gold values were found. 3 bedrock gold occurrences were found at Cloonacool. A significant gold soil anomaly was found at Cabragh. Geophysical targets established from Tellus survey
-Phase 1 Cloonacool Drilling:
All 9 holes returned plus 1 gpt gold. 200m wide gold-bearing structure discovered. Part of structure contains conductive graphite. Conductor is 4.5 km long. Eastern 1.5 km associated with high-grade gold float is top priority drill target.
