The Beryl Tong Rare Earths/Metals Project
The Beryl Tong project (The Property) is located in Northwestern British Columbia (BC), Canada near the Yukon border just east of the Alaskan Panhandle and southeast of the border of Alaska with the Yukon. The Property lies within the South Alaskan Tin/Tungsten belt of mineral occurrences and deposits that trends through the Northern Alaska Range southwards through to the far south-western edge of the Yukon border region then onwards to northwestern BC (Figure 1).
The Property consists of two claim blocks totalling 25 claim units with a combined area of 405.10 hectares (1001.1 acres US). Location of the Property is in a remote region known to host world class mega-deposits which the Windy Craggy is just west of the Project Area (Figure 2).

About The Property
There are two known documented mineral occurrences on the Beryl Tong namely the Wolframite Zone and the Partridge both are classed as a “showing” although having been worked on by several operators over the years including Strategic Metals Ltd in 2007, the Property results have shown encouragement.
The primary zone called the Wolframite is located on till and talus covered hillside on the north side of Partridge River, within the till and talus are two windows of glacially scoured bedrock about 50metres (m) apart. The host rocks are predominantly quartzites and mica feldspar schists and gneisses of the Yukon Tanana Terrane (famous for hosting gold mines and deposits), the Terrane is a continuation of the Northern Alaskan Tin belt. These rocks are basically roof pendants and inclusions within the regional surrounding granodiorites and granites of the Coast Plutonic Complex. In the area of the mineralized showing, the granites are classed as coarse grained biotite hornblende quartz monzonite.
Figure 3 shows the two mineralized zones occurring on either side of the valley.
Note: The location of the two mineralized zones is approximate, red dotted line is a surface linear feature of unknown disposition.
At the Wolframite zone, mineralization is in a swarm of sub-parallel veins of about 1 to 5 mm each made up of white quartz with envelopes of mica rich alteration sometimes called greisens. Greisens can reach economic proportions which are mined for their rich tin, tungsten as well as other elements of the rare metals class. In 2007, Strategic Metals Ltd completed a limited program of prospecting, mapping and rock sampling at the Wolframite Zone area. Two well mineralized vein samples assayed 2.78% and 2.51% tungsten oxide while the rest of the veins returned anomalous elevated values for tungsten, tin, gold, bismuth, gallium and beryllium. The slope where the outcrops occur are extensively talus covered whereas downslope the area is obscured by glacial till debris, so sampling was restricted but results encouraging. The outcrops were sampled for rare earths with very elevated results including Ytterbium 13.60 ppm, Dysprosium 17.45 ppm, Erbium 11.90 ppm, Bismuth returning grades beyond the assay limits of >250ppm, and Rubidium as high as 1140ppm.
The Partridge Vein zone is situated about 1.0 km west of and across the valley from the Wolframite zone is a minor quartz vein 1 to 4 cm wide within a 5.0-10m wide bench-like linear trending due north. The quartz vein consists of three episodes of quartz emplacement (clear, smoky, and chalcedonic) and appears to have post alteration with the inclusion of clay altered granitic fragments with up to 10% fluorite in some areas. The analytical results were anomalous but elevated and erratic in some elements including rare earths/metals. The sampling program at the Partridge was limited in scope as the Granitic rocks hosting the linear feature appeared not to be sampled for rare earth/metal elements. No rock samples have had any petrographic thin section analysis conducted to determine whether the granitic rocks held any invisible rare earth/metal minerals associated with the mafic phenocrysts.
Strategic Metals consultant concluded that the Property has received a preliminary search and investigation. The large system of tungsten hosted greisen sheeted veins appears to be attractive but the lack of bedrock exposure in the immediate area prevents any extensive appraisal. Normally greisen veins are softer than the surrounding host rock and as consequence; the best part of the mineralization will more than likely be covered by either talus or till which would require trenching or shallow thin wall drilling.
In 2012, the Property was visited by Bradley Wilson who further enhanced the property results through extending the soil/talus/rock sampling around the showing areas. He also identified the main host rock underlying the area appears to be an orange weathering, coarse grained biotite granite with miarolitic cavities up so several tens of centimetres across but the majority are much smaller. Pegmatitic zones and pods are also present up to a metre in width. The distribution of these cavities and pegmatites appear randomly placed within the intrusive. In addition, he noted the linear feature of unknown origin that has no outcrops contained within. His description of the Wolframite zone confirmed the previous operator account of the area with extensive course talus covered slopes. The depiction of the Wolframite zone was on par with Strategic Minerals description of a series of low outcrops exposed intermittently over a distance of about 200 metres exposing a series of sub-parallel quartz veins surrounded by mica rich halos (greisen). B. Wilson noted fine needles of beryl occurring within one vein a possible emerald in the development stage, also beryllium assay of 500ppm was located near the Wolframite zone. Soil sampling around the Wolframite zone yielded flat results indicating soil sampling at this location was useless even though the samples were taken downslope from the known tungsten mineralization (hillside transport of elements).
At the Partridge zone, B. Wilson took four “blind” randomly picked samples for potential tungsten mineralization; the results were disappointing but anomalous. Of the area, four soil samples and two rock samples were collected. Of the rock samples, only one had anomalous assays for the rare earth elements with gadolinium 10.7ppm, terbium 2.3ppm, dysprosium 14.8ppm, ytterbium 11.6ppm and samarium 9.0ppm. The rock sample was angular float from locally sourced bedrock, areas of the sample show a chalky alteration and quartz veining with a dark coloured opaque mineral (maybe a smoky quartz as the assay had elevated uranium values).
In conclusion, Brad Wilson summarizes the exploration program as a cursory prospecting of the area. Encouraging was the Wolframite zone extension of 200m being obscured by talus on all sides limiting the exposure of extending the potential mineralization. He failed to mention the anomalous elevated rare earth elements in the intrusive host rocks.
Regionally, the BC Government silt sampling program has highlighted the surrounding area with elevated fluorine in the creeks beyond the limited extent of the known mineralization (Figure 4).
Arrows show the area of drainage to the sample stations taken by the BC Government silt survey Samplers. Note the source area drainage of these anomalous fluorine samples.
What’s needed next?
Conduct a silt/soil sampling reconnaissance program in and around the anomalous fluorine flowing creeks. In conjugation with the above, a prospecting program sampling any outcrops exposed near the creek traverses. Also, randomly take granitic rock samples near the pegmatites for possible rare earth mineralization. Cost of next phase approximately $25,000. If within budget to further extend the known Wolframite zone by a surface pack sack drilling to try to get below the extensive talus cover surrounding this zone.

- The Project is located in the far reaches of Northwestern British Columbia, Canada and within the southern extension of the Alaskan Tin Belt.
- Access to the Property is via helicopter from Carmacks, Yukon
- Golden Tiger Minerals targeted this frontier project for encouraging rare earth/metal/tungsten assays and Beryllium up to 0.05%.
- As a result of the Company’s research in the area, two claim blocks totaling 25 units covering an area of 405.1hectares (1001.1 acres) were acquired at staking costs, the Company owns 100% with no encumbrances.
- The Company’s focus is to continue along trend a sampling/prospecting program with the known surface exposure of greisen veins in conjunction with the high Fluorine content in the creeks draining the southern extension of the main showing area.
- The Property has been explored by several operators in the past, most notably Strategic Minerals in 2007 and recently by a privately funded operator Brad Wilson M.Sc Geologist
- The former operators documented two Mineral Occurrences in the BC Government database; the main tungsten zone Wolframite and the Partridge.
- The area is underlain by a mixture of granite and granodiorite intrusions hosting rare earth elements. At the Partridge Zone, blind rock sampling by B. Wilson yielded encouraging rare earths; gadolinium 10.7ppm, terbium 2.3ppm, dysprosium 14.8ppm, ytterbium 11.6ppm and samarium 9.0ppm. The rock sample was grabbed from chalky altered granite.
- In 2012, B. Wilson extended the Wolframite zone some 200metres south of the original showing area discovered by Strategic Minerals, assays at this zone included a very encouraging tungsten values to 2.78% plus anomalous rare earths; Ytterbium 13.60 ppm, Dysprosium 17.45 ppm, Erbium 11.90 ppm, Bismuth returning grades beyond the assay limits of >250ppm, and Rubidium as high as 1140ppm.
- The previous limited amount of exploration on this ground is very encouraging, the area has the potential of hosting rare earths in the granites of gigantic-size proportions; the association of the rare earths in the granites is still a mystery that needs to be addressed.
- What’s next? New sampling and prospecting would increase the southern trend of the Wolframite zone by more than a kilometre and together with sampling the granite for rare earths, the possibilities are of gigantic portions as a bonus.
further work based upon my recommendation.
