Work History

 Staked as Cashel cl 1-8 (Y8629) in Jun/66 by J. McCormack.
 
Restaked as Cody cl 1-40 (YA95507) in Aug/86 by B. Harris who sold the claims to P. Peever. Peever carried out reconnaissance scale prospecting and rock sampling programs in Aug/86 and optioned the claims to Doron Exploration Inc.
 
In Jun/87 Doron Exploration staked Ruby cl 1-20 (YB806079) on north and west sides of the Cody claims. The company used a D-6 bulldozer to trench and sample silver bearing quartz veins located southeast of the occurrence location. In July and Aug/87 Doron Exploration employed a helicopter to carry out detailed geological mapping and extensive rock sampling on silver bearing veins located in the Cirque area (occurrence location). In Dec/87 the company staked Ruby cl 21-56 (YB12689) on the west and south sides of the Cody claims.

The 1988 exploration program was funded by Lacana Mining Corporation and operated by Doron Exploration. The company carried out a large regional exploration program from mid-May through to mid-July/88 the results of which led the company to expand the property 4 fold.
 
In Jul/88 Doron Exploration surrounded the Cody and Ruby claims with Pur cl 1-236 (YB20859) and staked Scot cl 1-30 (YB21111) on the northeast side of the property. The company also staked Pur cl 237-280 (YB21487) on the southwest side of the property. The expanded property covers Minfile Occurrence #105K 084, located to the northwest and Minfile Occurrences #105K 051 and 053, located to the southeast. Please refer to these occurrences for exploration work carried out in their vicinity.
 
From mid-July to the end of the exploration season (mid-Sept.) Doron Exploration carried out soil sampling on a plateau located above and west of the Cirque zone. The company also carried out blast trenching followed by bulldozer trenching on the Cirque zone and carried out detailed geological mapping and extensive rock sampling on the Cirque zone and the silver bearing quartz veins located southeast, down slope of the Cirque zone. 
 
Restaked as JRV’S cl 1-12 (YC07969) in Jul/97 by P. Risby. Risby staked JRV’S cl 13-20 (YC08097) 4.5 km to the southeast (Minfile Occurrence #105K 053) later in the month. Between Oct/97 and Apr/98 Risby surrounded the two claim blocks with JRV’S cl 21-174 (YC08376 - not staked sequentially). Once registered the claims were transferred to the Gullen Risby Family Trust.

Western Prospector Group Ltd optioned the JRV’s claims in Apr/98 and carried out a two day property examination (with Columbia Gold Mines Ltd) in May/98 which covered the Cirque zone (this occurrence) and the Arsenopyrite, Krist and Creek zones (Minfile Occurrences 105K 051 & 053). In Jul/98 the companies returned and spent two days collecting additional rock samples from the Cirque and Arsenopyrite zones and soil samples from the Arsenopyrite zone.

The option was subsequently assigned to Pacific Ridge Exploration Ltd which carried out detailed exploration on the southeastern portion of the claim group (Minfile Occurrence #105K 053) in 1999.
 
In Mar/2007 P. Risby restaked the main Cirque zone within JRV cl 41-44 (YC59958) for the Gullen Risby Family Trust.
 
In Nov/2010 Strategic Metals Ltd staked Snap cl 1-73 (YD118149) to the southeast. The following month the company restaked the occurrence within Snap cl 74-157 (YD12170). The claims were staked as part of the company’s enlargement of their Silver Range project which at the time was focused on the Keg occurrence/deposit (Yukon Minfile 105K 078) located approximately 27.5 km to the northwest.
  
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.
 
During the 2011 exploration season Strategic Metal/Silver Range Resources collected a combination of 20 grab and chip rock samples from the Cirque zone. The company also collected contour soil samples from around the Cirque zone.
  
On July 19, 2011 Strategic Metals shareholders approved the plan to spin-out the Silver Range project and the Mint property into a new company Silver Range Resources Ltd. On August 9, 2011 the Plan of Arrangement was approved by various securities regulators and Silver Range Resources became the owner/operator of the Silver Range project.
 
On August 29, 2011 Silver Range Resources purchased the JRV’S cl 41-44 claims (claims coving the core of Cirque zone) and other neighbouring JRV’S claims from Gullen Risby Family Trust.
 
In 2012 Silver Range Resources dug two trenches on the Bench showing (mineralized area located at lower elevation) located 900 m south of the Cirque zone. The company collared 4 diamond drill holes (336.33 m) later in the year. Three holes were collared on the main Cirque zone and 1 hole was collared on the Bench showing.

Capsule Geology

The occurrence is located approximately 12 km northwest of the historical Faro mine and mill site and 18 km northwest of the town of Faro in east central Yukon. 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. Access to the occurrence location is currently provided by helicopter however a rough tote road exists that runs north from the former Faro mine site to the occurrence area.

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 area is covered by deep overburden which makes geological mapping difficult. Based on limited mapping and drill-hole information the area is underlain by non-calcareous schist, phyllite and gneiss with lesser carbonaceous phyllite, marble, calc-silicate schist and metabasite assigned by Pigage (2004-10) to the Upper Proterozoic to Cambrian Mount Mye Formation. Geologists employed by Silver Range Resources assigned the rocks to the Gull Formation which is a regional designation in the Selwyn Basin; the Mount Mye Formation applies to units in the more specific Anvil district.
 
The Mount Mye Formation rocks are intruded by granite, quartz monzonite, granodiorite and minor syenite of the mid-Cretaceous Anvil Batholith. The Mount Mye rocks form large roof pendants within the batholith and have been intruded by granitic sills that are coeval with the batholith.  Both the roof pendants and batholith have been cut by green, fine-grained andesite to coarse grained hornblende-plagioclase porphyry dykes and quartz-feldspar porphyry dykes of likely mid-Cretaceous or Early Tertiary age. Quaternary alluvium, glacial and glaciofluvial deposits blanket broad valleys in the area.

The Cirque zone lies within a small, steep, northeast-facing cirque which lies at the north end of a north-trending ridge. Mineralization was initially discovered in talus at surface and later in bedrock exposed in hand and bulldozer trenches. The mineralized area measures approximately 1 000 by 500 m in area.
 
Mineralization is hosted within a variety of vein types, which are largely restricted to brittle fracture zones in granitic rocks, whereas the overlying sub-horizontal schist units behaved in a more ductile fashion as a cap rock inhibiting fracture and vein formation. Mineralization found in the schists is at least an order of magnitude less than that found within the granites. Opinion is mixed regarding the emplacement of intermediate dykes which cut both intrusive and metasedimentary units. Lueck (1988), thought the veins may be related to the emplacement of the dykes while Robertson and Wallis (1989), thought that although a spatial relationship is evident between the veins and dykes, it is likely a function of two different processes operating on the same fracture pattern rather than a genetic relationship between the two.
 
Doron Exploration described 4 types of mineralized veins; 1)milky or sugary textured quartz veins with or without pyrite, galena, sphalerite and/or arsenopyrite; 2) poorly exposed quartz-chalcedony-limonite veins within clay and carbonate alteration; 3) silver-lead- zinc-arsenic veins containing abundant quartz, chalcedony, pyrite and carbonate (rhodochrosite) gangue; and 4) massive sulphide veins that consist primarily of galena. Some veins also host minor tetrahedrite-tennantite and proustite-pyrargyrite (“ruby silver” sulphosalt minerals).
 
Widths, grades, textures and mineralogy are extremely variable over short distances. In a few instances veins widths of up to 1 m were recorded over short distances (1-3 m long) of otherwise narrow breccia veins. These wider sections form where the vein has a lense of banded pale cherty quartz along one wall and not by the widening of the sulphide-rich portion of the vein. Although there are several predominant strike directions of the veins, individual veins can occasionally be seen to change direction over a few metres, causing considerable uncertainty in determining the strike length and continuity of the veins. Considerable textural variations occur often with banding along vein margins and a breccia zone in the centre of the veins which indicates that there were multiple stages of vein filling. The central brecciated vein zones sometimes contain small rounded fragments of granite wall rock rimmed by chalcedony or rhodochrosite. Rhodochrosite also occurs as patches, fragments and open space fillings within veins or as cross-cutting veinlets. Open spaces within the veins are commonly lined with quartz prisms. Weathered vein surfaces are usually black due to strong manganese staining. Limonitic and hematite staining is also locally prevalent. Unmineralized or pyrite and arsenopyrite-bearing siliceous veins are common within the zone.

Muscovite in alteration zones adjacent to the mineralized veins gives average Ar/Ar ages of 100.6 ± 1.1 Ma, indicating that the mineralization is related to early, highly peraluminous phases of the Mt Mye Batholith (Mortensen and Ballantyne, 1992). The galena is highly radiogenic and probably derived from the intrusion or remobilized from the surrounding sedimentary rocks.

The Cashel claims were likely staked to explore for massive sulphide mineralization similar to that found on the neighbouring Faro property/mine (Yukon Minfile #10K 061) located approximately 12 km to the southwest. During the late 1960’s and 70’s the area surrounding the occurrence location was likely restaked within portions of other claim blocks as the area saw a exploration boom associated with identifying massive sulphide targets. Later assessment reports note that the silver bearing quartz veins were known at the time however with the emphasis on massive sulphide mineralization no substantial exploration was made to evaluate them.
 
Peever identified manganese-stained quartz-carbonate veins containing variable sulphides at the occurrence site and 900 m to the southeast. Initial samples assayed up to 5.9 g/t gold and 12 284 g/t silver. Other veins were located in the southeast end of the claim block (Minfile Occurrence 105K 051)
 
In 1987 Doron Exploration walked a D-6 Cat (bulldozer) to the claims from the neighbouring Faro mine site. The company tried to reach the occurrence site, located in a cirque at the top of a ridge but were stopped by topography.  The company trenched the area located 900 m to the south known as the Lower veins (called Bench showing by Silver Range Resources). Later in the summer the company used a helicopter to set up a camp in the cirque. Employees blasted and hand trenched the mineralized quartz veins and carried out detailed geological and structural mapping.
 
Doron Exploration’s 1987 sample results map appears to be offset by at least one claim length to the northeast. The veins located in the cirque returned grab samples which assayed up to 9 876 g/t silver while more detailed chip samples returned up to 1 208 g/t silver over 2 m. It doesn't’t appear the company filed any assays for the Lower veins.

The 1988 exploration season saw Doron Exploration carry out regional geological mapping and rock sampling across their entire property which encompassed 4 separate Minfile occurrences. The last half of the season saw the company concentrate on the Cirque occurrence (this occurrence). The company carried out soil sampling on the ridge located above and south of the Cirque zone. The area is underlain by metasedimentary rocks and does not host any significant soil development or organic matter thus did not return any useful information.
 
Prospecting identified quartz-rhodochrosite veins southeast of the Cirque zone. These veins appear to be located further south than the Lower veins or the Bench showing. Significant silver values were found in selected samples, with moderate gold content and generally high manganese and arsenic values. Grab samples returned up to 4 071.7 g/t silver, 3 379 ppb gold, 10 000 ppm lead, 6 660 ppm zinc and 7 7 462 ppm arsenic.  The company also sampled quartz veins and quartz manganese veins discovered in a ridge slope located north of the Cirque zone. Grab samples collected from this area returned much lower values (i.e. 1 to 28.5 ppm silver), however one grab sample returned a high of 157.0 g/t silver.
 
Doron Exploration collected a number of grab samples from quartz veins outcropping in schists located to the north above the Cirque zone. Most of the veins consisted of quartz with variable amounts of galena, sphalerite or arsenopyrite. The grab samples returned up to 334.9 g/t silver, 245 ppm gold 17 650 ppm lead, 31 095 ppm zinc and 830 ppm arsenic. Although metal values and vein widths are not significant, the vein indicate that in at least a few instances, fracturing was capable of breaching the schist cap overlying the granites which host silver-mineralized veins in the Cirque zone.
 
Approximately 4 km to the southwest, Doron Exploration noted a recessive rusty zone which is traceable for approximately 3 km. The “Orange zone” appears to consist of clay, limonite and siderite alteration of the granite. Material recovered from float consists of quartz, buff coloured chalcedony, and pale grey and dark grey siliceous breccia with altered granite clasts, pyrite blebs, limonite, siderite and rare manganese staining. Rock samples collected from the zones returned negligible values for silver, gold, lead, zinc and arsenic. Although of little economic value the zone provides a visual marker in the area.

In the assessment report detailing results of the 1988 exploration program Doron Exploration stated that although the program was successful in that good exposures of the veins were obtained and sampled, the veins are much narrower and fewer in number than the amount of vein float exposed in the Cirque zone would indicate. As the strike of the many veins is subparallel to the slopes of the cirque, the volume of float exaggerates the actual vein density. Similarly, extensive sections of altered granite exposed in bulldozer trenches seems anomalous with respect to the few narrow veins seen in the same sections but in these areas the trench cuts almost parallel to the strike of the veins, again exaggerating the volume of altered granite. In addition, the high grade silver-rhodochrosite-sulphide breccia veins form a very small proportion of the veins responsible for the observed alteration. The company recommended drilling 3 diamond drill holes to test for mineralization at depth. The holes were never completed.
 
The two day property examination conducted by Columbia Gold Mines in May/98 saw the company visit the main areas of mineralization located within the JRV’S claims. The group sampled the Cirque zone but only 1 chip sample collected from manganese-stained, silicified breccia-quartz vein zone containing rhodochrosite and micro fracture fillings of galena and local tetrahedrite returned any significant results (~70 g/t silver over 2 m). The group returned in mid-July and carried out a more thorough sampling program. Grab and chip samples returned an average of 550 g/t silver and 0.70 g/t gold. Trench assays and bulk sampling indicated the potential for higher silver grades (1 096 g/t silver over 2 m). Prior sampling of 15 subparallel ruby silver veins returned 324 g/t silver over 1.9 m. No further work was carried out and Risby allowed the claim group to gradually shrink until only 3 groups of 4 JRV”S claim remained. Each claim group covered areas where previously exploration had identified silver bearing quartz veins. Once the bulk of the JRV’s claims had lapsed, Risby paid in lieu to keep the remaining three claim groups in good standing.
 
Strategic Metals staked the Snap claims following the discovery of silver-polymetallic mineralization in the fall of 2010 at the Keg Main zone (Minfile Occurrence #105K 078) located approximately 27.5 km to the northwest. Contour soil sampling completed by Silver Range Resources (company spun off from Strategic Metals) outlined a large silver soil anomaly centered over the Cirque zone (details never publicly released). Twenty rock samples collected from the zone returned assays ranging from 9.04 to 2 460 g/t silver and 0.051 to 1.12 g/t gold, averaging 408.9 g/t silver and 0.22 g/t gold. The longest chip sample assayed 327.0 g/t silver, 0.089 g/t gold and 3.53 % lead over 3.6 m (Dec. 15/2011 news release). The company believe the mineralization may be genetically related to the epithermal style mineralization discovered at the neighbouring Hammer zone (Minfile Occurrence 105K 084) located approximately 4 km to the northwest.
 
The three 2012 drill holes (189.42 m) collared in the Cirque zone were drilled from the same drill setup. The holes tested for mineralization below historical trenches dug in the zone. The remaining drill hole (146.91 m) tested for mineralization below the Bench showing (Doron Exploration’s Lower vein showing) located 900 m southeast of the main Cirque zone. Silver Range has not publicly released results from any of the drill holes or any trenching conducted in 2012.
 
No further exploration work has since been carried out on the occurrence.
