Fieldwork Commences on Eagle Plains’ Black Diamond Antimony and Precious Metal Project
Fieldwork Commences on Eagle Plains’ Black Diamond Antimony and
Precious Metal Project
Cranbrook, B.C., June 24th, 202 5: Eagle Plains Resources (TSX -V:”EPL”) has
mobilized personnel to commence fieldwork on the Black Diamond Property, located
35km W of Invermere, British Columbia. The 866 ha, road-accessible property covers the
Black Diamond structural zone, which has been traced for over 12km and hosts high-grade
polymetallic silver -lead-zinc-antimony mineralization. The project is 100% owned by
Eagle Plains with a 2% NSR held by Eagle Royalties containing a 1% buy-back clause.
See Black Diamond Property Information and Map here
The Black Diamond property has been held by Eagle Plains since 1996. Located within
the Toby Creek area, the steeply -dipping north/south -oriented structure is exposed for
approximately 760m vertically , and interpreted to have at least 1.6 km of strike -length
within property boundaries. Historical pits, trenches and tunnels are located at irregular,
exposed intervals over approximately 3km of the Black Diamond structure trace.
Most of Eagle Plains work has focused on the northern part of the property , in the area of
the historic Black Diamond workings (BC MINFILE 082KSE049). At the Battleship Zone,
massive quartz vein material up to 8m in width occurs at the intersection of two structural
splays. In 1995, a four -hole, 179.1m, helicopter-supported drilling program funded by a
private partnership targeted the Battleship area. Results ranged from trace values to the best
intersection in Hole 95 -02 at 28.0m to 31.0m, which graded 93.73 g/t silver, 9.66% lead
and 5.17% zinc over 3.0m . (true thickness estimated at approximately 1.4m). Concurrent
with the 1995 drill program, continuous chip panel-sampling of an historic al 66m-long
tunnel located 60m vertically below the drill set-up returned an average of 746.3 g/t silver,
25.0% lead and 4.95% zinc over a 24m section which ran along the structure. Within this
section, 6m of the tunnel length assayed 1444.7 g/t silver, 50.4 % lea d and 5.37%
zinc. Antimony results from the panel sampling ranged from trace values up to 1180ppm
Sb over a 1m interval. 1
The current program will focus on the southern part of the property in the area of the Silver
Spray Zone (BC MINFILE 082KSE007). Historic grab samples of mineralized quartz vein
material exposed in trenches returned values including 3.19g/t Au, 2286.1 g/t Ag and
1.63% Sb (RW95C -04) and 1 .28 g/t Au , 2813.2 g/t Ag and 7.44% Sb (RW95C -06). 1
Prospecting programs by Eagle Plains in 1996 2 and 201 2 3 located additional historic
workings in the Silver Spray area . Geochemical analyses ranged from trace values up to
higher grade samples including:
• CDBD96R-08: 1500 g/t Ag, 2.55% Cu, 55.4% Pb, > 10,000ppm Sb
• CDBD96R-12: 759 g/t Ag, 24.1% Pb, 6.6% Zn, > 10,000ppm Sb
• TTBDR004: 1955 g/t Ag, 0.97% Cu, 13.75% Zn, > 10,000ppm Sb
• TTBDR008: 0.94 g/t Au, 1650 g/t Ag, 3.53% Cu, 2.11 % Zn, > 10,000ppm Sb
The 1995 and 1996 analyses were done using 30 element ICP with Aqua Regia Digestion
and the 2012 program used a 35 element ICP with Aqua Regia Digestion. All of the
programs used a Fire Assay finish on select over limit samples.
An airborne geophysical survey (magnetometer and electromagnetic) completed in 200 4
outlined two prominent linear features that appear to be related to the known mineralization
and historical workings.
2025 work will include soil sampling and prospecting along the interpreted trace of the
Black Diamond Structure and associated structural splays , targeting antimony and
associated precious metal mineralization . Recent interpretation of LiDAR data by Eagle
Plains has located topographic anomalies in the area of the high gold and antimony values,
which may represent additional trenches and adits, and will be followed up on as part of
the current program.
Exploration is being conducted and managed by TerraLogic Exploration Inc. of Cranbrook,
BC.
Snowstorm Sb / Au Project
As well as the Black Diamond Property, Eagle Plains holds another project with significant
antimony mineralization. The 2084ha Snowstorm Property, located in the historic Slocan
Mining Camp is underlain by 6 BC Minfile occurrences, one of which, the White Eagle
(BC MINFILE 082KSW126), is covered by an historical Crown Grant. Mineralization at
the Snowstorm is associated with quartz -calcite veins hosted in sediments. No historical
drilling has been reported on the property.
See Snowstorm Property Information and Map here
The West Ridge (BC MINFILE 082KSW197) vein has been explored with several trenches
and a 15m deep shaft. A selected grab sample of the mineralized vein assayed 1540 grams
per tonne silver, 41.1 per cent lead, 16.1 per cent antimony and 1.58 per cent copper (ARIS
18136). 4 As well as antimony, the Snowstorm hosts high -grade gold mineralization. The
Silver Sparrow occurrence (BC MINFILE 082KSW146) consists of two separate quartz
veins some 90 metres apart, which have been explored by trenches and a 6m deep inclined
shaft. The best grab sample from the vein assayed 27.5 grams per tonne gold, 1083 grams
per tonne silver, 56.2 per cent lead and 0.55 per cent zinc (ARIS 18136). 4 A one day field
program by Eagle Plains in 2024 located the historic Pine Tree occurrence, interpreted to
represent the strike length extension of the Silver Sparrow Vein ~70m along strike to the
east. KBSWR014 a float sample of vein material, returned 76.30 g/t Au, 56.30 g/t Ag, and.
3.30% Pb.5
At the Lakeview occurrence (BC MINFILE 082KSW198), two mineralized quartz veins
have been exposed by two trenches. A composite sample of vein material taken from the
western end of one of the trenches assayed 144 grams per tonne gold, 158 grams per tonne
silver, 6.04 per cent lead and 3.47 per cent zinc (ARIS 18136). 4
Rock grab samples are selective samples by nature and as such are not necessarily
representative of the mineralization hosted across the property. Some of the above results
were taken directly from MINFILE descriptions and assessment reports (ARIS) filed with
the BC government. Management cautions that historical results were collected and
reported by past operators and have not been verified nor confirmed by a Qualified Person
but form a basis for ongoing work on the subject properties. Management cautions that
past results or discoveries on proximate land are not necessarily indicative of the results
that may be achieved on the subject properties Management cautions that rock grab
samples are selective samples by nature and as such are not necessar ily representative of
the mineralization hosted across the property.
