Kamuck Property, showing eU responses and individual samples on prospected areas identified by aerial imagery
– Company Selected to Receive $200,000 Ontario Government Grant –
VANCOUVER, British Columbia, Jan. 31, 2024 (GLOBE NEWSWIRE) -- Solstice Gold Corp. (TSXV: SGC) (“Solstice”, “we”, “our” or the “Company”) is pleased to provide an update on the exploration program at its Church and Kamuck Projects in the Quetico Subprovince, located approximately 85 km and 200 km NE of Thunder Bay, Ontario, respectively in the actively explored Quetico lithium district.
Emerging Quetico Lithium District
Spodumene discoveries reported by exploration groups in 2023 are defining a greatly expanded area with high lithium potential within the Quetico subprovince. The Quetico Lithium District is centred around the Georgia Lake Lithium deposit (owned by Rock Tech). In 2023, a new spodumene discovery was reported by Pegmatite One ("PGA"1) west of the Georgia Lake pegmatites and within 15 km of Solstice's Church Property. Spodumene was also reported in 2023 to the east of Georgia Lake by Tearlach ("TEA") on their Georgina Properties2, immediately adjacent to Solstice's Gathering Lake claims, optioned to Green Technology Metals. Solstice's Kamuck Property is located just to the east of these discoveries and exhibits abundant fertility indicators.
Principal Findings
Pablo McDonald, Solstice CEO stated, “After discovering several 20 to 30m wide pegmatites on the Church Property on the first few days of prospecting, our more in-depth exploration efforts throughout the fall showed a trend of lithium enrichment in alkali feldspars across the southern part of the property, as well as radiometric anomalies that are similar to those seen proximal to spodumene-bearing pegmatites in the region. We have also seen abundant pegmatite on both Kamuck and Church, with promising LIBS readings in an unknown mineral of up to 3.0% Li2O. The combination of positive signs coming out of these properties after initial prospecting show that these areas have the potential to host LCT Pegmatites and I’m therefore very excited to get back on the ground with detailed prospecting and sampling.”
Both properties produced favourable results in 2023, which continues to show promise for Solstice’s projects in the Quetico Lithium District:
Preliminary exploration at Church in August of 2023, covering less than 5% of the area, delineated five 12-30m-wide pegmatites with quartz, albite and potassium feldspar along with books of muscovite, garnet, and beryl or fluorapatite3.
High Lithium values in alkali feldspars (50 - 280 ppm using LIBS4) define a lithium-enriched trend along the Southern end of Church. This trend largely aligns with the anomalies in radiometric data which continue to the north of Church and are spatially related to the Pegmatite One spodumene occurrence.
LIBS analysis of unknown minerals at both Church and Kamuck have registered strong lithium responses. At Church, readings of up to 1.18% Li2O in an unknown mineral are coincident with the southern radiometric anomaly. At Kamuck, readings of up to 3.0% Li2O in a green mineral, likely fluorapatite were recorded after only one day of prospecting5.
Detailed Results
Further exploration of the area included prospecting and sampling throughout the fall of 2023, whole rock geochemical and LIBS analysis. Further study of publicly available geological and geophysical data has also helped to reveal promising geochemical and structural trends related to pegmatites on the Project.
Key results include:
Analysis of Ontario Geological Survey (OGS) radiometric data6 show Equivalent Uranium (“eU”) anomalies that are related to a major structure – the Black Sturgeon River Fault (“BSRF”) and related faults which are also developed near Pegmatite One’s recent spodumene discovery and other known pegmatites in the area (see Figure 1). The eU anomalies are interpreted by Solstice to be associated with a potassic granite source intrusion(s) which may also be the source of related pegmatites on the Property. Some pegmatites in the area are known to be uranium-bearing7.
Geochemical analysis using LIBS has identified a lithium-enriched trend of over 50 ppm Li in alkali feldspars (50 – 280ppm), from potassic granites or pegmatites. Similar readings in alkali feldspars have been shown to be reliable indicators for the presence of spodumene in known lithium districts8,9.
Sampling to date at Church suggests that elevated lithium in alkali feldspars is largely coincident with the pronounced eU anomaly. More regionally, the Pegmatite One spodumene occurrence and mapped (OGS) fertile pegmatites also display a close spatial relationship with eU anomalies (see inset, Figure 1)
eU anomalies coincident with lithium enrichment in alkali feldspars at Church suggest potential fractionation outwards from core potassic (and uranium-enriched) source intrusion area(s). This is supported by low K/Rb ratios (a measure of fractionation) in pegmatites sampled to date outside the main area of eU enrichment (Figure 1).
LIBS analysis in an unknown mineral has registered readings of up to 5,470ppm Li (1.18% Li2O) in a newly identified area of pegmatites in the SE area of the Project.

Much of the Church Property has not been prospected or sampled. Based on the promising results that are clearly tied to eU anomalies that have analogs to the North along the BSRF, these areas have the potential to host LCT Pegmatites, and therefore the next step on the Property will be to cover the rest of this area with detailed prospecting and sampling.
Kamuck Property
Solstice acquired the 31km2 Kamuck Property in October 2023 after a one-day property due diligence examination. Key observations include:
Confirmation of a well exposed pegmatite swarm covering a 1km by 800m area which was initially identified using aerial imagery (Figure 2). The pegmatite is typically coarse-grained plagioclase feldspar with abundant indicators of fertility including books of muscovite, garnet, cordierite, and possible fluorapatite10. The pegmatite swarm correlates with a pronounced ENE and NNE trending, 3.9km long eU radiometric anomaly11 that satellite imagery shows has extensive exposure.
Elevated Li content (LIBS readings of up to 3.0% Li2O) in a green mineral, likely fluorapatite12. According to Selway et.al., “the presence of blue or green Mn-rich fluorapatite indicates that the pegmatite has economic potential for Li-Cs-Ta”13. The fluorapatite also contains up to 1.02% Mn (1.31% MnO) which is also noted as a component in other fluorapatites in LCT pegmatites.
The pegmatite swarm lies at the western end of, and is coincident with, part of a prominent ~3km ENE-trending eU anomaly interpreted to be a potential fault structure along which additional pegmatites may be developed. This, and other prominent structures and eU anomalies will be prospected in the 2024 field season.
Upon seeing positive correlations between eU anomalies and lithium values in alkali feldspars at Church and Kamuck, Solstice subsequently staked a strong eU anomaly adjacent to Kamuck to bring its entire area to 43 km2.

Solstice Selected to Received $200,000 Ontario Government Grant
The Company has also been selected to receive grant funding of up to $200,000 under the Ontario Junior Exploration Program (“OJEP”) from the Ontario Government. This amount will cover up to 50% of eligible exploration costs, to a maximum of $200,000 in respect of expenditures incurred by the Company during the period from April 1, 2023 to February 15, 2024. The Company also received a $200,000 OJEP Grant for the exploration program on its SLP Project in 2023.
“As the global search for critical minerals intensifies, our government’s Ontario Junior Exploration Program (OJEP) gives us a major competitive advantage and ensures Ontario will be a leading global supplier of critical minerals,” said George Pirie, Minister of Mines. “Our government's $200,000 investment in Solstice Gold’s Church Project will help develop this promising lithium deposit in northwestern Ontario and create jobs. Lithium is a vital component in the manufacturing of electric vehicles, and it is great to see companies exploring for the critical minerals that will help us build an integrated supply chain in Ontario.”
“We would like to thank the Ontario Government for the approval for funding under the OJEP program. We look forward to using these funds to extend our exploration program at our Church Project, which is in the heart of the Quetico Lithium District, only 85km from the Port of Thunder Bay” commented Pablo McDonald, Solstice CEO.
Data Sources and References
LIBS:
Initial analysis of samples from Solstice's site visit were completed using a Sci-Labs Z-300 LIBS (laser-induced breakdown spectroscopy) analyzer. Lithium data were calibrated against LCT pegmatite standard GTA-06. Data should be considered semi-quantitative, but are independently confirmed by whole rock data (K/Rb values, for example). In addition, at least four analyses per mineral were carried out (two in “Geochem” mode, two in “Element Pro” mode).
Whole Rock Analysis:
Sample material weighing from 1 to 2 kg is selected and placed in plastic bags. Sample details and a GPS coordinate were recorded. A sample tag with the sample number is tied with flagging tape to an example of the sample and left in the field. A duplicate sample tag is placed in the sample bag. The samples were delivered directly to the lab in Thunder Bay, Ontario by Solstice employees. Analysis method: Peroxide (Total) Fusion, ICP-OES & ICP-MS with 55 elements that include detection levels for Li of 15ppm - 50,000ppm and Rb of 0.4ppm - 5,000ppm (ActLabs code UT7). Sodium peroxide fusion provides total metal recovery and is effective for the decomposition of sulphides and refractory minerals which are common to pegmatites.
