Appia Announces Significant Geochemical Critical REE Assay Results at Alces Lake Project, Saskatchewan, Canada
January 15, 2024 (Source) — Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQX: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the “Company” or “Appia”) is pleased to announce significant initial geochemical assay results derived from the 2023 drilling program conducted on the Magnet Ridge Zone at its Alces Lake Project in Northern Saskatchewan. These promising findings mark a pivotal milestone in the Company’s ongoing commitment to advancing exploration and development initiatives within the prolific Athabasca Basin area. The drilling campaign, instrumental in extending mineralization further to the south-southeast (SSE) underscores Appia’s dedication to unlocking the full potential of this project.
Highlights:
- Assays of up to 1.57 wt.% (15,700 ppm) Total Rare Earth Oxides (TREO) were returned, with thickness and grades increasing to the south-southeast
- Highest Grade Intercepts:
- Hole 23-MR-001: 21.91 m width @ 0.366 wt.% TREO, including 2.67 m @ 0.660 wt.% TREO
- Hole 23-MR-002: 25.5 m width @ 0.329 wt.% TREO, including 2.11 m @ 0.389 wt.% TREO and 4.68 m @ 0.520 wt.% TREO
- Hole 23-MR-003: 30.5 m width @ 0.292 wt.% TREO, including 1.00 m @ 0.537 wt.% TREO
- Hole 23-MR-006: 6.31 m width @ 0.267 wt.% TREO
- Hole 23-MR-007: 9.29 m width @ 0.384 wt.% TREO, including 0.50 m @ 0.650 wt.% TREO
- Hole 23-MR-010: 1.80 m width @ 0.246 wt.% TREO
- Mineralization intervals occur from near surface to < 85 metres depth (Table 1); multiple intervals in 23-MR-002 and 23-MR-003, extending downward in a westerly direction.
- Future exploration to continue in the west-southwest (WSW); extending downward into current intersections towards the mineralization at Magnet Ridge West (MRW)
Commencing on June 11th, 2023, Appia initiated a comprehensive 3456.72-metre helicopter-supported diamond drilling program, concluding all field operations on August 24th. Prioritizing specific areas spanning the entire property, with dimensions of approximately 20 kilometres in length and 5 to 7 kilometres in width, the drill program systematically targeted key zones. The Company has received all assay results stemming from its 2023 summer geochemical exploration initiative. Appia is engaged in the compilation, review, and interpretation of these results across all investigated areas. Updates will be disseminated as both results and interpretations become available.
Recent petrographic/mineralogical studies indicate that the Rare Earth Elements (REE) mineralization at Magnet Ridge is hosted primarily in monazite.
“The identification of the Magnet Ridge Zone following the 2022 drill campaign was a major success to further delineate potential mineralization at Alces Lake. We can now extend this zone along this segment of the structural corridor,” stated Stephen Burega, President. “We completed 11 step-out holes from eight collars, and we are seeing continued mineralization with thick intercepts.”
On June 24, 2023, the southern extension drilling at Magnet Ridge concluded, encompassing 11 drill holes with a combined depth of 1092 metres (see Figures 1 and 2, Tables 1, 2, and 3). A press release dated July 5, 2023, disclosed noteworthy findings, revealing that five drill holes identified significant mineralization intersections, with core intersection widths reaching up to 21.91 metres. Notably, Table 1 details two drill holes that recorded multiple intersections.
Geological and geophysical interpretation has yielded valuable insights:
- The down-dip extension of Magnet Ridge toward the west-southwest (WSW), remains open.
- Mineralization encountered terminates abruptly at the SSE end of the Thorium (eTh) anomaly, attributed to an east-northeast cross-structure-a steeply dipping fault that vertically offsets the mineralization down-dip on its southern side.
- The eTh radiometric high exhibits a surface expression approximately 450 metres long by 250 metres wide. The clear down-dip extension to the WSW is evident in the X-section of drill holes 23-MR-001, 002, and 003 (refer to Figure 3, with the location indicated in Figures 1 and 2). This consistency aligns with representative X-sections from prior years’ drilling in the northern and central segments of Magnet Ridge (Figures 4 and 5, with locations depicted in Figure 1).
“The first three holes successfully intercepted pebbly biotite schist (glimmerite) mineralization from 32 to 70 metres depth along core axis,” affirmed Dr. Irvine Annesley, VP of Exploration, “Ongoing drilling in 2023 consistently suggests the potential for the down-dip extension of the mineralization to extend WSW, potentially reaching depths connecting to Magnet Ridge West (MRW).”
The Company is poised to explore mineralization at MRW within a fold structure, with plans to conduct grid/drill testing at depths ranging from 50 to 175 metres. This strategic initiative reflects Appia’s commitment to advancing exploration to uncover valuable critical mineral resources.
“The 2023 Alces Lake exploration campaign completed a successful season of prospecting, channel sampling, and diamond drilling across the entire large property. Specifically, here at Magnet Ridge, our team was able to delineate the SSE-most extent of the Magnet Ridge mineralization (see Figures 1 and 2),” says Lead Geologist Kahlen Branning, “Our prospecting team has uncovered a multitude of new, potential drill targets on the property that necessitate further detailed exploration, many of these display anomalous radioactive counts, from 5,000 counts per second (cps) to 40,000 cps. These new zones match our original hypothesis regarding the location of low-to-high-grade mineralization along the main regional shear zone and within the fold nose/hinge zone area of a large regional fold structure.”
After concluding operations at Magnet Ridge, the drill was relocated to the Jesse Zone where the Company completed 9 diamond drill holes (DDHs). Subsequently, the drill was directed to a particularly promising anomaly within the Western Anomalies area, leading to the completion of 3 diamond drill holes. Advancing further, the drill was repositioned to explore the Hinge and WRCB Zones, to test new targets, exhibiting count rates of up to 30,000 cps, as delineated by the ongoing 2023 prospecting and channel sampling program. Notably, certain targets underwent drilling using both a diamond drill and a backpack drill, the latter validating emerging RAMP-HD targets at the surface for subsequent drilling initiatives.
