Sorrento Resources Provides Update on Exploration on Bottom Brook Project, Newfoundland

Rhea-AI Summary

Sorrento Resources (OTCQB: SRSLF) provided an exploration update for the Bottom Brook REE project in Newfoundland and Labrador on December 2, 2025. The company said drill permits are submitted and pending, with diamond drilling planned to begin early 2026 comprising approximately 1,000–2,000 m. Drilling will target the Lost Pond zone where historic high‑grade REE intercepts were reported and will use larger HQ core (~63.5 mm) instead of historic BQ core (~36.5 mm) to enable more practical metallurgical testing. After drilling, Sorrento plans follow‑up geophysics, prospecting and soil sampling across the large, relatively unexplored property.

Positive

• Drill permits submitted and currently pending
• Planned diamond drilling of approximately 1,000–2,000 m early 2026
• Upgrade from BQ to HQ core (~63.5 mm) for metallurgical testing
• Follow-up program includes geophysics, prospecting and soil sampling

Negative

• Drilling contingent on permit approvals, creating timing uncertainty
• Historic promising intercepts were not previously followed up

Market Pulse Summary

This announcement details Sorrento’s plan for 1,000–2,000 m of diamond drilling at the Bottom Brook REE project starting in early 2026, shifting from historic ~36.5 mm BQ core to ~63.5 mm HQ core to improve metallurgical test work. Follow‑up geophysics, soil sampling, and prospecting are planned across a largely underexplored property. With no recent news history provided, investors may watch for permit approvals, drill collar locations, and any subsequent assay or metallurgical results as the next key milestones.

Key Terms

diamond drilling technical

"Drilling commences early in 2026 and will consist of approximately 1,000 to 2,000m of diamond drilling."

Diamond drilling is a method that uses a rotating drill with industrial diamonds on the bit to cut and retrieve cylindrical rock samples (cores) that preserve the sequence of underground layers. For investors, these cores act like a geological “biopsy,” providing direct, verifiable information about mineral presence, grade and continuity—data that underpins resource estimates, project valuation, drilling risk and financing decisions.

geophysical methods technical

"Drilling will be followed up with geophysical methods, prospecting, and soil sampling."

Geophysical methods are ways of 'scanning' the ground using measurements of physical signals—like sound waves, magnetism, gravity or electrical currents—to detect and map what lies beneath the surface without digging. For investors, these techniques act like medical imaging for a property: they reduce the chance of costly, unsuccessful drilling by improving where to look, estimating scale and risk, and informing project costs and timelines.

soil sampling technical

"Drilling will be followed up with geophysical methods, prospecting, and soil sampling."

Soil sampling is the practice of collecting small, representative pieces of ground and testing them for minerals, nutrients, contaminants or physical properties. Results tell investors whether a property likely contains valuable resources, agricultural potential, construction suitability or environmental problems that affect cleanup costs, permits and future revenue — think of it as taking a few bites of a cake to judge whether the whole is worth buying.

drill core technical

"Historically, the area was drilled with BQ drill core which has a diameter of ~36.5mm."

A drill core is a long, cylindrical sample of rock pulled from beneath the surface during exploration drilling that preserves the layers and minerals exactly as they occur underground. Investors care because lab tests on core reveal what minerals and concentrations are present and how they’re distributed, which is the primary evidence used to estimate a deposit’s size, quality and commercial potential—like reading the cross‑section of a layered cake to judge whether it’s worth buying.

metallurgical test work technical

"This will allow for more practical metallurgical test work."

Laboratory and pilot-scale experiments that determine how a mineral deposit can be processed to recover valuable metals, measuring likely recovery rates, suitable processing methods, costs and technical challenges. For investors, this work is like testing a recipe before opening a restaurant: it shows whether the resource can be turned into saleable metal efficiently and predictably, which directly affects production forecasts, cost estimates and project risk.

Vancouver, British Columbia--(Newsfile Corp. - December 2, 2025) - Sorrento Resources Ltd. (CSE: SRS) (OTCQB: SRSLF) (the "Company" or "Sorrento") a Canadian exploration company focused on the acquisition, exploration, and development of mineral projects in Atlantic Canada, is pleased to provide an update on exploration activities Bottom Brook REE project (the "Project") located in the province of Newfoundland and Labrador.

Bottom Brook REE

- Drill Permits have been submitted and are currently pending.
- Drilling commences early in 2026 and will consist of approximately 1,000 to 2,000m of diamond drilling.
- Drilling will be followed up with geophysical methods, prospecting, and soil sampling.

Drilling will focus on the Lost Pond target, an area which high grade REE mineralization has been intersected in historic drilling. The company plans to follow up on these intercepts along strike and dip with a larger diameter of drill core. Historically, the area was drilled with BQ drill core which has a diameter of ~36.5mm. Sorrento intends to drill the project with HQ drill core which has a diameter of ~63.5mm. This will allow for more practical metallurgical test work.

When drilling is finalized, the company plans to follow up with a target generation exploration program. This will include geophysics, soil sampling, and prospecting. Due to the large size of the property, it remains relatively unexplored. Similar programs in the past have yielded promising results but were never followed up on.

About the Bottom Brook Project

The Bottom Brook Project is made up of 16 mineral licenses which have a combined 606 individual claims for a total area of 15,150 hectares. It is located approximately 40km South of the City of Corner Brook which has a deep-water port, skilled workforce, and many service providers. The property is accessible via a network of secondary roads immediately adjacent to the Trans-Canada Highway. There is a transmission line which also runs through the western portion of the property

Previously drilled high grade total rare earth oxide (TREO) include:

• 4.37% over 5m
• 4.47% over 5.6m
• 8.19% over 2.00m
• 15% over 0.5m
• 11.02% over 1.05m
• 1.269% over 7.5m

The REE mineralization in Bottom Brook is characterized by monazite-enriched horizons. The distribution of Rare Earth Oxides in a high-grade core sample from Bottom Brook is almost identical to the giant carbonatite Bayan Obo deposit - a major REE reserve estimated at more than 57.4 million metric tons grading at 6% and accounts for nearly half of global REE production (Penney and Reid, 2009). The Bottom Brook REE mineralization has also been compared to the Steenkampskraal monazite deposit in South Africa (Wilton, 2024). Which is one of the highest-grade REE deposit globally with a current mineral resource estimate of 665,000 tonnes at an average grade of 14.5% TREO.

The presence of mineral resources on other projects is not an indication that the Bottom Brooke Project will have a resource of similar size or grade as no resource estimation has been completed on the Project.
