Work History

This occurrence record covers the Keg Main deposit and its associated mineralized zones which lie within 89 mineral claims.
 
Examination of claim and staking records shows that the Keg East zone and the east half of the Keg deposit were staked within Ivan cl 1-66 (93615) in Nov/65 by Anvil Mining Corporation Ltd. The claims were staked to cover anomalies detected during a previously flown airborne magnetic and electromagnetic survey. In 1966 the company collared 4 diamond drill holes (463.3 m) to test various geophysical anomalies.
 
The western half of the Keg deposit was staked within Hal cl 1-24 (Y39) in Feb/66 by Yukon Copper Ltd.  The company also staked Mark cl 1-88 (99171) and cl 97-112 (99259) to the southwest at the same time. In Mar/66 the company staked Tara cl 1-56 (Y687) on the northern boundary of the Ivan and Hal claims and Dane cl 1-8 (Y759), cl 9-88 (Y1110), cl 89-96 (Y9823) and cl 97-103 (Y9831) on the eastern boundary of the Ivan claims. In Aug/66 the company added Hal cl 25-28 (Y9811) and cl 29-36 (9815).
 
Yukon Copper carried out airborne magnetic and electromagnetic surveys and geological mapping and soil sampling programs in 1966. Sometime before 1967 the company reorganized and changed its name to Northern Empire Mines Ltd. In 1967 Northern Empire carried out grid soil sampling and geological mapping programs and bulldozer trenched various anomalies in 1968.

In Jun/69 Inter-Tech Development and Resources Ltd restaked the Ivan claims as Ter cl 1-66 (Y35284).

In Nov/71 Northern Homestake Mining Ltd purchased the assets of Northern Empire Mines Ltd, (property consisted of Tara, Hal, some remaining Dane and Mark claims) thus obtaining the western half of the Keg property. The company conducted further bulldozer trenching in 1972 before optioning the property to Ridgemont Mining Corporation Ltd, a wholly-owned subsidiary of Cyprus Mines Corporation (operator of the neighbouring Faro Mine Complex). Ridgemont now controlled the entire footprint of the present day Keg property including the Keg deposit and the Keg East zone.
 
In Mar/73 Ridgemont Mining restaked the Ter claims as Dana cl 1-4 (Y67987) and cl 5-76 (Y75001). It’s likely the Hal claims were located further east then previous claim maps showed. The company carried out grid based soil sampling over both the Hal and Dana claim blocks.
 
In Jul/74 Ridgemont Mining staked Halo (fractional) cl 1-12 (Y79648) between the Dana and Hal; claim blocks. The company carried out further soil sampling, in addition to induced polarization (IP), magnetic and limited electromagnetic geophysical surveys. In Sep/74 the company collared 3 diamond drill holes (498 m) to test the geophysical anomalies.
 
In early 1975 Cyprus Mines Corporation restructured and became Cyprus Anvil Mining Corporation. Following restructure all assessment reports were filed under the Cyprus Anvil Mining Corporation name. In Jun/75 the company collared 3 diamond drill holes (627.4 m) on the Halo and Dana claims. In Aug/75 the company staked Irma cl 1-31 on the northwest border of the Hal claims and in Oct/75 carried out limited magnetic and gravity geophysical surveys on the claims.

Following the completion of the 1975 exploration season Cyprus Anvil dropped its option on the various Northern Homestake Mining claims. In May/76 Northern Homestake Mining Ltd changed its name to Thunderwood Explorations Ltd and tried to option their claims to another company but failed to do so.
 
In Aug/77 Cyprus Anvil carried out an IP survey over a gravity anomaly previously detected on the Irma claims. In Jun/78 the company tested the anomaly with a single diamond drill hole (159.4 m). The Irma claims were eventually allowed to lapse.

Restaked in Jun/90 as Keg cl 1-16 (YB27551) and 21-40 (YB27567) by YGC Resources Ltd. The staking covered all mineralized areas discovered to that date. The company carried out prospecting and limited rock and soil sampling programs. The claims were allowed to lapse in Mar/93.
 
In Sep/97 R. Berdahl staked BP cl 4 (YC65807) approximately 1.25 km west of the occurrence location to cover an area known as Zone “B”. Berdahl also staked BP cl 5 (YC65871) 3.5 km to the southeast.
 
In Dec/2009 the Keg Main zone was restaked within Keg cl 1-15 (YD11773) by Strategic Metals Ltd. In Mar/2010 the company staked Keg cl 16-53 (YD33666) which encompassed the East zone and outlying areas of mineralization.
 
In early Jun/2010 Strategic Metals commenced exploring their Keg claims. The company carried out detailed soil sampling over the Keg Main showing and areas located to the east and west. Numerous historic trenches and showings were geologically mapped and sampled. On June 8, 2010 Strategic Metals optioned the BP 4 claim from R. Berdahl in return for shares of the company.

In early July the company collared 4 diamond drill holes (958.27 m) on the Keg Main zone to test previously identified mineralization. Later in the month, following the receipt of preliminary exploration results, the company staked Keg cl 54-369 (YD62954). In late July the company began flying a helicopter borne ZTEM geophysical survey over the property. The survey was part of a larger regional survey carried out on the company’s variously owned claim blocks.
 
In Aug/2010 the company staked Keg cl 370-549 (YD27420) and cl 550-569 (YD28051). In Sep/2010 following receipt of initial drill results Strategic Metals staked Keg cl 570-1300 (YD31870) and cl 1301-1340 YD90531).
 
In Nov/2010 the company staked Keg cl 1301-2044 (YD00451) and cl 2045-2270 (YD117925) to cover geophysical anomalies identified from the ZTEM geophysical survey flown earlier in the summer. The company also announced that the Keg property would be joined with the Rebel property (located 15 km to the south) and other newly discovered neighbouring areas of porphyry hosted silver-zinc-lead-copper mineralization to form the Silver Range Project.
 
On January 11, 2011 Strategic Metals announced its intention to spin-out the Silver Range Project and the gold rich Mint Project (Minfile Occurrence 115F 087) located in southwestern Yukon into a new precious metal focused company; Silver Range Resources Ltd. The company and its shareholders would receive shares and purchase warrants in the new company.
 
In Jun/2011 Strategic Metal commenced their 2011 exploration program. The company carried out a large exploration program on its entire Silver Range Project. Work carried out on this occurrence includes grid based soil sampling and limited rock sampling over areas located west, south and southeast of the Keg Main zone. The company also conducted detailed geological mapping over the Keg Main zone and an extensive diamond drill program. Twenty-eight diamond drill holes (10,783.59 m) were collared on the Keg Main zone, 9 diamond drill holes (2,286.68 m) were collared to test the Keg East zone and 2 diamond drill holes (608.69 m) were collared to test coincident conductivity, chargeability and magnetic geophysical anomalies located 400 and 800 m north of the Keg Main zone.

On July 19, 2011 Strategic Metals shareholders approved the plan to spin-out the Keg Project and the Mint property into a new company Silver Range Resources. On August 9, 2011 the Plan of Arrangement was approved by various securities regulators and Silver Range Resources became the owner/operator of the Keg property.
 
In Jan/2012 Silver Range Resources announced they were initiating a preliminary metallurgical testwork program on mineralized samples collected from the Keg Main zone.
  
Silver Range Resources commenced their 2012 exploration season in May/2012. On the Keg Main occurrence the company carried out limited rock sampling over known areas of mineralization and grid soil sampling over parts of the Keg East zone and areas located to the northeast and northwest. The company collared 28 diamond drill holes (8,377.49 m) on the property of which 21 were collared on the Keg Main zone, 2 on the Keg East zone and 2 holes labeled as scout holes. Three holes were abandoned.
  
In addition to their field exploration program the company undertook various laboratory studies including floatation testing, composite sample analysis and tailings characterization (i.e., toxicity tests etc.). The company contracted a geophysical company to combine, process and analyze all geophysical data collected on the property and began collecting environmental base line, heritage and access route data.
  
In Jun/2012 Strategic Metals completed the work commitments need to obtain a 100% interest in the BP 4 claim, subject to an outstanding net royalty smelter (NRS) interest held by the underlying vender.

On November 20, 2012 Silver Range Resources announced an initial 43-101 compliant resource estimate and initial metallurgical test work results for the newly named Keg Main deposit. Based on a cut-off grade of 16.0 g/t silver, the Keg Main deposit hosts an inferred resource of 39.760,000 tonnes grading 30.25 g/t silver, 0.26% lead, 0.77% zinc, 0.15% copper, 265.7 ppm tin, 5.77 ppm indium and 138.06 ppm cadmium.  
 
Metallurgical results from seven drill core composites show that the deposit’s mineralization responds very well to conventional copper/lead/zinc floatation processing with excellent recoveries of payable metals and acceptable concentrate grades in copper, lead, and zinc concentrates.
 
In May/2013 Silver Range Resources filed an amended technical report on the Keg property to clarify several concerns raised by the British Columbia Securities Commission. The concerns related to sections of the report authored by individuals not considered “independent qualified persons”. The amended report addressed these concerns. None of the securities commission’s concerns related to the actual technical data used to calculate the Keg Main deposit’s estimated inferred resource, and the resource calculation remain in good standing.
  
During the 2013 exploration season Silver Range Resources carried out limited diamond drilling and exploration activities on other targets located within the Silver Range Project area. No substantial exploration work was carried out around this occurrence.
 
In Jun/2014 Strategic Metals transferred 100% ownership of the BP 4 claim to Silver Range Resources. The claim was never part of the original spin-off transaction due to unfulfilled work commitments owed to the underlying vendor. 

Capsule Geology

The occurrence is located approximately 40 km north of the town of Faro and approximately 356 km by road from Whitehorse. Access to the occurrence location is currently provided by helicopter however road access is being studied. The Faro area is world renowned for its zinc-lead-silver-barite massive sulphide deposits, mining of which began in 1969 and continued with interruptions until 1997. 
  
The occurrence is located within the Selwyn Basin a tectonic element comprising deep water clastic rocks, chert and minor carbonate that accumulated along the North American continental margin during Paleozoic time. In the occurrence area the Selwyn Basin lies immediately northeast of units belonging to Slide Mountain and Yukon-Tanana terranes the most easterly of the allochthonous terranes. Deformation and metamorphism associated with accretion of the terranes was initiated in Jurassic and culminated in Cretaceous. More recently, strike-slip faulting along the Tintina fault resulted in about 450 km of dextral offset during Early Tertiary time. The area is located about 40 km northeast of the fault.
 
The rocks in the vicinity of the occurrence comprise various Paleozoic-age strata that have been juxtaposed by a complex series of Jurassic to Cretaceous high angle and thrust faults. Structure in the area is dominated by moderately southwest-dipping or flat lying strata that are imbricated by several large northwest-trending, northeast directed thrust faults. The Paleozoic strata are sandwiched between two major Mid-Cretaceous igneous bodies; the Anvil Batholith to the southwest and the Teddy Caldera to the northeast. Both bodies are elongated parallel to the regional northwest to southeast structural trend.
 
Geological mapping was carried out around the occurrence area in 2011, 12 and 13 by geologists employed by Silver Range Resources. The lack of visible outcrop hampered these efforts. The area is underlain by Upper Cambrian through Permian aged sedimentary rocks that have been assigned to 4 main units. The oldest exposed rocks have been assigned to the Upper Cambrian to Lower Ordovician Rabbitkettle Formation. They comprise dark grey to grey-brown and sometimes white, laminated to thinly bedded quartzose siltstone and fine grained sandstone with minor shale horizons.

Devonian to Mississippian Earn Group grey shales and black, thin bedded chert occur above the Rabbitkettle Formation. The stratigraphic relationship between the two units is unknown. Mississippian Tay Formation conformably overlies the Earn Group and comprise thin to medium beds of grey, silty limestone to calcareous siltstone between dark grey to black variably quartz-rich siltstone to shale. The youngest rocks in the area belong to Carbonaceous to Permian Mount Christie Formation and consist of thin to medium bedded, maroon, black and grey-brown cherts.
   
A small Mid-Cretaceous Selwyn Suite pluton comprised of light grey medium grained biotite-hornblende granodiorite cut the sedimentary rocks 2 km southwest of the Keg Main deposit (occurrence location). No intrusive rocks have been observed within the occurrence area.
  
A zone of pervasive hydrothermal alteration overprints sections of both Mount Christie Formation and Tay Formation Keg property. Within this alteration zone, rocks are commonly light grey to light pinkish-grey, massive and very fine-grained and host minor veinlets and disseminations of sulphide minerals. The alteration zone measures approximately 3,000 by 5,000 m and is open along strike to the east and the west.
  
Several east-southeast trending thrust faults dip to the south and imbricate the stratigraphy on the property. Fracture and vein orientation in and around the Keg Main deposit are broadly grouped into two sets. One set dips very steeply to the west and strikes south-southeast and the other dips sub-vertically north and strikes west. Both sets commonly contain sulphide minerals in veins and fractures but the west striking set is more abundant but has finer fractions.
  
Diamond drilling has outlined two main zones of mineralization; Keg Main (deposit) and Keg East. Mineralization within the Keg Main zone is controlled by a combination of structure and stratigraphy within strongly hydrothermally altered and locally skarnified limestone and siltstone of Tay and/or Mount Christie Formations. Intense silicification of these formations makes it difficult to determine which unit is the primary host. The structural control is typified by fracture-fillings, while stratigraphic control is characterized by disseminations to semi-massive mineralization within calc-silicate altered limey horizons.

Sphalerite, chalcopyrite and galena occur in varying amounts with pyrrhotite, pyrite and arsenopyrite and rare stannite. The sulphide minerals are generally coarse grained. They typically comprise 1 to 10% of the rock, often increasing to between 20 and 50% over metre-scale intervals within skarnified horizons. A general zonation has been observed with pyrrhotite and chalcopyrite dominating the sulphide assemblage in the deeper and western parts of the zone and galena contents higher in the upper and eastern parts. The western and central parts of the mineralized zone are notably depleted of calcium relative to the adjacent wall rocks, but calcite gangue is common in veins within the eastern part of the zone. The variations in relative sulphide abundance and gangue minerals are interpreted to indicate the deeper and western parts of the zones are more proximal to the core of the hydrothermal cell and the upper and eastern parts are more distal.
  
Mineralization at the Keg East zone is generally similar to that observed within the eastern part of the Keg Main zone and is likely part of the same mineralization system. Several features, including the presence of calcite gangue, lower pyrrhotite and chalcopyrite contents and high silver to lead ratios, suggest the Keg East zone is in a more distal setting than Keg Main zone.
  
*Examination of early staking and assessment records (1960s and 70s) shows that the maps employed at the time were very inaccurate. Most assessment work was tied to actual claims and since many of the claims were not located properly, the true location of many anomalies, trenches and drill holes are in doubt. The Minfile author has tried to relate such results to modern (known) locations.

Anvil Mining Corp’s 4 diamond drill holes collared in 1969 on the Ivan claims did not intersect any sulphides of economic interest and the company did not assay any of the drill core.
 
Yukon Copper/Northern Empire Mines geophysical, geochemical and reconnaissance geological programs outlined 4 zones of interest which were explored with more detailed geophysical and geochemical sampling. The areas were labeled grids A, B, C, and D. Grid A covered the Keg Main area and areas to the west. Within Grid A the company bulldozer trenched two main areas referred to as zones A and B plus a smaller unnamed area located to the south. Zone A, the most westerly of the zones, was exposed for a length of 60 m and returned assays up to 2.8% zinc, 0.4% copper, 0.01% lead and trace values for gold and silver over a width of 4.5 m. Zone B located 610 m to the east was exposed for a length of 12 m and returned assays up to 1.3% zinc, 0.05% copper, and 3.4 g/t silver over a width of 3 m.
  
Ridgemont Mining’s 1973 geochemical sampling program outlined a 1,220 m long by 300 m wide copper, lead and zinc soil anomaly centered approximately 3 km east of Zone B and overtop the Keg Main zone. Patchy less anomalous areas extended 600 to 100 m to the south. A second anomalous area measuring approximately 500 m long by 60 m wide lies approximately 1.25 km to the east (Keg East zone). The anomaly is rich in lead and zinc but the anomalies are not coincident. The company carried out various geophysical surveys in 1974 and identified coincident magnetic, induced polarization (IP) and gravity geophysical anomalies within the larger of the two soil anomalies (assessment reports for the geophysical work cannot be located).
  
Ridgemont Mining’s 1974 diamond drill program tested the largest soil anomaly. All three of the drill holes intersected minor amounts of disseminated copper, lead and zinc sulphides. Hole 74-2 intersected 200 m of weakly mineralized material with assays returning 0.52% copper, 4.40% zinc, 2.08% lead and 247 g/t silver over 3 m at the top of the hole. These holes were located in the vicinity of the current Keg Main deposit.

The 1975 drilling program was supervised by Cyprus Anvil Mining Corporation which emerged from the restructuring of Ridgemont Mining/ Cyprus Mines Corporation. The three drill holes were collared to test the down-dip extent of mineralization encountered in 1974. One hole (75-6) located approximately 1 km north of the other drill holes, failed to reach its target. Drill hole 75-4 returned 0.34% Cu over 33.5 m and hole 75-5 returned 0.35% copper over 34.9 m. A 12.0 m intersection from drill hole 75-4 assayed 0.42% copper, 0.64% zinc and 10.3 g/t silver.

Cyprus Anvil’s 1978 drill hole was collared on the Irma claims and was located approximately 8 km northwest of the 1974-75 drilling. The hole tested a coincident IP and gravity anomaly but only intersected graphite. None of the core was assayed. It appears all claims in the area lapsed by the end of 1980.
  
YGC Resources 1990 exploration program was carried out by Archer Cathro & Associates (1981) Ltd and was aimed at evaluating the potential for volcanogenic massive sulphide mineralization similar to the neighbouring Faro deposits.  Archer Cathro, supervised the majority of the previous soil sampling and initial bulldozer trenching conducted in the mid-1960s and early 1970s, thus they already possessed the key data needed to evaluate the property. The company sampled all known mineralized outcrops and collected a line of soil samples north of known anomalies. The company also re-assayed selected portions of drill core recovered from the 1974-75 drill programs. Results from 1990 generally correlated with earlier results. Gold content of the known mineralization was checked and no significant precious metal content was found. Archer Cathro summarized that the wide spread, relatively low grade fracture filling sulphide mineralization was apparently related to an unroofed Cretaceous intrusion and not volcanogenic in origin.
 
R. Berdahl staked 7 individual BP claims in 1997 to cover sulphide mineralization previously discovered in the surrounding region. BP claim #4 covered Zone B which up to that time hosted the best visible mineralization in the area. Berdahl did report any work on the claim and appears to have kept the claim in good standing by “paying in lieu” of assessment work.

Archer Cathro supervised all of Strategic Metal’s exploration work thus giving the company a head start on their 2010 exploration program. The program was aimed at verifying previous results. The company collected grid based soil samples across all areas of known mineralization and areas detected in previous geochemical surveys. Results outlined 3 areas of very strongly elevated silver-lead-copper and tin values over the Keg East, Keg Central ((Main) – occurrence location) and Keg West areas. Overall the anomalies outlined an area measuring 4,500 m long by 1,500 m wide. Limited rock sampling of previously discovered mineralization in the Keg Main zone returned weakly to strongly anomalous results for silver, zinc, lead, copper, tin and bismuth with strong indium and scattered gold support.
  
The four 2010 drill holes were collared near the centre of the soil anomaly underlying the Keg Main zone and in the vicinity of the 1974 and 75 drill sites. However, the 2010 holes were drilled at moderate angle northward under geochemical and geophysical anomalies to test a steeply dipping, structurally controlled zone. All four holes intersected 50 to 150 m long intervals of disseminated and fracture-filling mineralization within silicified and skarnified sedimentary rocks. Mineralization consisted of sphalerite, chalcopyrite and galena in varying amounts with pyrrhotite, pyrite and arsenopyrite. The best drill hole, Keg 10-1 returned 50.09 g/t silver, 1.2% zinc, 0.65% lead. 0.14% copper, 217 ppm tin and 9.55 ppm indium over 125.7 m and bottomed in mineralization. The drilling partially tested 550 m strike length of the Keg Main zone. The company used the initial exploration results from this area and others to greatly increase their claim holdings in the region.
  
Strategic Metals carried out detailed petrology, mineralogy, mineral chemistry and basic geothemometry studies over the winter of 2010-11, on various rock samples collected from the Keg Main and East zones. The results of the studies suggest that the mineralization system within the property is porphyry related.
 
The 2011 soil sampling program expanded the soil geochemical anomaly to the west-southwest and the southeast. At the Keg Main zone the majority of the drill holes were drilled at 100 m centres on an 800 m long grid. Two holes were drilled to test coincident conductivity, chargeability and magnetic anomalies. All of the holes collared on the Keg Main zone intersected broad intervals of silver-lead-zinc-copper-tin mineralization, within strongly silicified and locally skarnified limestone and siltstone of the Tay and Mount Christie Formations. The most significant silver-rich interval obtained graded 70.55 g/t silver, 0.54% lead, 0.60% zinc. 0.17% copper, 778 ppm tin and 1.77 ppm indium over 104.70 m (from 25.5 to 130.15 m) in hole KEG-11-009. The drilling extended the Keg Main zone to a strike length of 850 m and to vertical depths of 350 m, remaining open to expansion in both strike directions and to depth.

Diamond drilling conducted on the Keg East zone located 1,000 m east of the Keg Main zone tested approximately 300 m of strike length. The 7 diamond drill holes intersected mineralization similar to that observed at the Keg Main zone. Several features, including the presence of calcite gangue, lower chalcopyrite contents and very high ratios of silver to lead suggest that the Keg east zone is located at a more distal setting than the Keg Main zone. The best results from the drilling were obtained from drill hole Keg-11-14, which intersected a well-mineralized stockwork fracture zone that returned an average of 30.81 g/t silver together with lead-zinc-tin-indium values over a 70.11 m interval.
  
The 2012 diamond drill program extended the Keg Main zone, east and westward such that at the end of the program the zone was traced over a strike distance of 1,100 m and across approximate true widths up to 300 m wide (locally up to 450 m wide) and to a maximum depth of 350 m. Within this zone, Silver Range Resources outlined an extended high-grade corridor of near surface mineralization in the northern part of the Keg Main zone measuring approximately 900 m in strike length. The best result of 2012 was obtained from drill hole Keg-12-47 which returned 63.45 g/t silver, 0.48% lead, 0.43% zinc, 0.09% copper, 447.6 ppm tin and 0.96 ppm indium over 68.75 m from 6.64 m to 75.39 m. A single step-out drill hole (Keg 12-59) testing on-trend soil geochemical anomalies collared 700 m to the east of the Keg Main zone (and approximately 70 m north of previous Keg East zone drilling) intersected encouraging mineralization in favourable host rocks, grading 31.89 g/t silver, 0.39% lead and 0.33% zinc over 13.4 m.
  
On November 20, 2012, Silver Range Resources released the first independent 43-101 compliant resource estimate for the Keg Main zone which became known as the Keg Main deposit. Of the 69 modern diamond drill holes, 53 holes totaling 18 377 m intersected the mineralized solid (block of mineralization) used to calculate the resource figure. The resource estimate for the Keg Main deposit was initiated by constructing a wire-frame 3D solid model in “GEMS” (geology and mine planning software). Three-dimensional solids were manually digitized from the available drill data and were used to constrain the interpolation of mineralization. The model was constructed based upon lithological boundaries and structural controls. A total of three different lithological units were used in the modelling process.

Silver Range Resources calculated resource figures for various silver cut-off grades and settled on a 16 g/t silver cut-off grade. Based on a 16 g/t silver cut-off grade the Keg Main deposit hosts an open pitiable inferred resource of 39,760,000 tonnes grading 30.25 g/t silver, 0.26% lead, 0.77% zinc, 0.15% copper 265.7 ppm tin, 5.77ppm indium and 138.6 ppm cadmium. As part of the technical report prepared for the resource estimate the company released various metallurgical test results. Metallurgical results from seven drill core composites show the Keg Main deposit mineralization responds very well to conventional copper/lead/zinc floatation processing. The company reported average recovery rates of 88.6% zinc, 82.4% lead, 69.4% copper, 80.0% silver, and 82.9% indium.
