The BLANN (BN) occurrence is located on the east side of Deception Mountain, on the Fox property, approximately 73 kilometres northeast of 100 Mile House.

The area is underlain by metasedimentary rocks of the Proterozoic-Paleozoic Snowshoe Group, along the south margin of a granitic pluton informally referred to as the Deception stock.

Two main mineralized areas are identified on the Fox Property. The first area discovered with wide spread tungsten occurs at the Nightcrawler-Discovery zones (Fox-South area), adjacent the south flank of the Deception stock. This area includes the eastern extension of the Nightcrawler, termed the Creek Zone and the South Grid zone, south of the Fox (Discovery) prospect. The second area is on Deception Mountain (Fox-North area) including, from south to north the 708, BN, RC (Ridley Creek) and BK Zones on its eastern side and the Fox North and NW Deception zones on the upper north flanks of the mountain.

Locally, bedrock exposures include skarn, calc-silicate schist, quartz-biotite schist and quartzite, locally cut by aplitic, pegmatitic and granitic dikes. Layering and schistosity show gentle to moderate dips to the southwest. Vesuvianite and scheelite with trace molybdenite mineralization are hosted in thin bands of oxidized calc-silicate skarn that are within a broader assemblage of skarn material.

The calc-silicate unit has been mapped at surface from the BN zone in the south, through the RC (MINFILE 093A 259) zone, to the BK (MINFILE 093A 261) zone to the north over a distance of approximately 2.5 kilometres. A completed mineralogical description can be found in the Ridley Creek (MINFILE 093A 259) occurrence.

Initial work in the BN, RC and BK zones in 2010-2011 led to positive tungsten values along with anomalous zinc, indium bismuth, and locally gold and silver values. The highlights of 2012 drilling at the BN zone include hole F12-27, which intersected three mineralization zones, the best being 14.8 metres grading 4.04 per cent tungsten trioxide, 0.91 per cent zinc, 4.51 grams per tonne indium and 4.1 grams per tonne silver (Press Release, Happy Creek Minerals Ltd., November 19, 2012). Calc-silicate and skarn sections of drill hole F12-27 consist of thin bedded and banded/foliated to mottled, pale orange to dark red or brown colored garnet, pale to dark green colored pyroxene, diopside, brown vesuvianite, amphibole and quartz. Variable intensity of silicification and discrete quartz veining and less than a few centimetre veinlets, typically parallel to subparallel to bedding/foliation is common. Scheelite occurs as disseminations and clusters occur throughout the calc-silicate unit, variable from trace to strong concentrations. Associated pyrrhotite dissemination and blebs/clusters present locally with rusty halos and fracture-fill structures (Assessment Report 33695).

In early 2017, Happy Creek Minerals released an updated mineral resource estimate, using a greater than 0.2 per cent tungsten tri-oxide cut-off grade, with a total indicated resource for the RC (MINFILE 093A 259) zone of 486,000 tonnes grading 0.818 per cent tungsten tri-oxide and a total inferred resource for the combined RC and BN zones of 361,000 tonnes grading 1.568 per cent tungsten tri-oxide (Desautels, P. (2017-03-10): NI 43-101 Resource Update for the RC Zone and Maiden Resource Estimate for the BN Zone of the Fox Tungsten Project).

In early 2018, Happy Creek Minerals released an updated mineral resource estimate, using a greater than 0.175 per cent tungsten tri-oxide cut-off grade, with a total indicated resource for the RC (MINFILE 093A 259) zone of 582,400 tonnes grading 0.826 per cent tungsten tri-oxide and a total inferred resource for the RC, BN and BK zones of 565,400 tonnes grading 1.231 per cent tungsten tri-oxide (Desautels, P. (2018-02-27): NI 43-101 Resource Update for the RC and BN Zones and Maiden Resource Estimate for the BK Zone of the Fox Tungsten Project).

In 2025, drilling at the northwest side of the BN Zone intersected several calc-silicate horizons that support a stacked layer model with one horizon some 200 metres below surface. The 2025 drilling clearly indicates the calc-silicate horizons and associated tungsten mineralization are open to the west and north beneath Deception Mountain and there remains potential for additional horizons at depth. Highlights at the BN zone include hole F25-16: 1.00 metre grading 0.88 per cent tungsten tri-oxide from 105.0 m downhole and 1.65 metres grading 0.57 per cent tungsten tri-oxide from 218.3 m downhole; hole F25-17: 2.50 metres grading 0.25 per cent tungsten tri-oxide from 106.2 m downhole and 2.00 metres grading 0.79 per cent tungsten tri-oxide from 215.0 m downhole.

WORK HISTORY

The area has been explored in conjunction with the Fox occurrence (MINFILE 093A 211). The Fox property was optioned by Happy Creek Minerals Ltd. in December 2004 and an exploration program comprising grid layout, soil and rock geochemical sampling, prospecting, geological mapping, trenching and diamond drilling was completed through 2011. In 2007, six samples from the Blann showing returned up to 5.64 per cent tungsten (Assessment Report 30824).

Work in the Fox-North mineralized area (Deception Mountain East) intensified in 2010 and 2011, focusing on more detailed prospecting, hand trenching, rock and silt sampling, culminating with 415.4 metres of BQ diamond drilling in 2011. In 2012, Happy Creek Minerals Ltd. completed a 29-hole NQ diamond drilling program on the Fox property. Five of the holes targeted the BN showing, with all five holes intersecting significant mineralization.

In 2013 and 2014, Happy Creek Minerals continued programs of geological mapping and drilling on the Fox property, primarily on the RC (MINFILE 093A 259) zone and surrounding area. In 2015, Happy Creek Minerals completed a program of airborne magnetic and radiometric surveys, soil sampling, prospecting and geological mapping. Eight diamond drill holes, totalling 1579 metres, were also completed on the Creek zone near the east end of the Nightcrawler (MINFILE 093A 258) zone (Fox-South mineralized area).

In 2016, Happy Creek Minerals completed a program of trail construction, soil sampling, surface chip and channel sampling in 11 trenches, rock sampling, geological mapping and 28 NQ diamond drill holes, totalling 2331.2 metres, on the BN, BK, RC and South Grid zones. Nine of these holes, F16-17 to F16-25 were spotted at the BN zone. Drilling yielded intercepts including 5.1 per cent tungsten tri-oxide over 4.1 metres in hole F16-17, 0.97 per cent tungsten tri-oxide over 5.0 metres in hole F16-20 and 1.36 per cent tungsten tri-oxide over 4.0 metres in hole F16-22 (Desautels, P. (2017-03-10): NI 43-101 Resource Update for the RC Zone and Maiden Resource Estimate for the BN Zone of the Fox Tungsten Project).

In 2017, Happy Creek Minerals completed a further 66 NQ diamond drill holes, totalling 6983 metres, on the BN, RC, Creek and South Grid zones, along with prospecting, geological mapping and hand trenching. Drilling of 38 holes on the BN zone yielded up to 2.980 per cent tungsten tri-oxide over 5.1 metres in hole F17-29 (Desautels, P. (2018-02-27): NI 43-101 Resource Update for the RC and BN Zones and Maiden Resource Estimate for the BK Zone of the Fox Tungsten Project).

Happy Creek Minerals Ltd. continued mostly grass-roots exploration across their Fox property and adjacent mineral tenures throughout 2018 to 2024. In 2025, 14 NQ diamond drill holes totalling 1304.5 metres were completed at the RC and BN zones, focusing on the expansion of the tungsten resource (PR REL Happy Creek Minerals Ltd. Dec. 17, 2025).
