Recent Company History

Over the last few months, Core Silver issued a series of exploration updates focused on Laverdiere and Silver Lime. On Oct 09, it confirmed multi‑kilometre high‑grade Cu‑Mo‑Ag mineralization at Laverdiere. Subsequent October and November releases highlighted new porphyry veins at Copper Creek, widespread gold and silver at Silver Lime, and deeper porphyry mineralization at Laverdiere, including hole LAV25-010 and later LAV25-011. These updates consistently emphasized expanding strike length, depth extent, and pending assays.

Analysis

The stock moved +7.4% in the session following this news. A strong positive reaction aligns with prior exploration catalysts where constructive Laverdiere updates were followed by gains, such as moves of 7.43% and 15.56% after earlier porphyry and mineralization news. However, with 2025 assays still pending, results risk re‑pricing if grades disappoint. Investors watching past patterns should note that upside historically depended on confirming continuity and grade once analytical data arrived.

Key Terms

porphyry, skarn, epithermal, sulphosalt, +4 more

8 terms

porphyry technical

"porphyry copper-molybdenum-silver (Cu-Mo-Ag) mineralization intersected in drill hole"

A porphyry is a type of large, underground mineral deposit that contains valuable metals such as copper, gold, or molybdenum, often spread over a wide area. Think of it as a giant underground treasure chest, where the metals are embedded in rock formations. These deposits are important to investors because they can be the source of significant resource extraction projects with the potential for substantial economic returns.

skarn technical

"linked to an exposed high-grade iron-copper-molybdenum-gold skarn occurrence"

A skarn is a type of rock that forms when hot magma interacts with surrounding rocks, causing chemical changes and the creation of mineral-rich deposits. For investors, skarns can indicate areas where valuable metals or minerals might be concentrated, making them important in the search for natural resources and potential mining opportunities. Recognizing skarns helps in assessing the potential value of land or mineral rights.

epithermal technical

"Epithermal quartz-carbonate veins are abundant throughout the upper section"

Epithermal describes a type of mineral deposit formed when hot fluids near the Earth’s surface deposit metals such as gold and silver into cracks and porous rock, often creating concentrated ‘veins’ or pockets. For investors, epithermal deposits matter because they can host high-grade, easily accessible ore that may lower extraction costs and shorten the time from discovery to production, affecting project value and exploration risk.

sulphosalt technical

"overprinted by late silver-bearing sulfosalt and specular hematite-molybdenite veins"

A sulphosalt is a group of naturally occurring minerals made of metals combined with sulfur and so‑called semimetals (like antimony, arsenic or bismuth); think of them as complex recipes where different ingredients are chemically bound together. They matter to investors in mining and materials because they can host valuable metals (silver, lead, copper, antimony), influence how easily ore can be processed, and bring regulatory or environmental complications when toxic elements are present — much like a mixed ingredient that changes both the cooking method and cleanup.

breccias technical

"silver-bearing sulfosalt and specular hematite-molybdenite veins and breccias"

Breccias are rocks made of broken, angular fragments cemented together like a rocky mosaic, often formed by underground fracturing, volcanic activity, or mineralizing fluids. They matter to investors because breccias can act like sponge-like hosts for valuable minerals — their cracks and voids often concentrate metals such as gold, copper, or silver — so finding extensive breccias can signal a promising target for mining and future resource value.

chalcopyrite technical

"quartz-vein hosted molybdenite and chalcopyrite mineralization (±pyrite ±bornite)"

Chalcopyrite is a common copper-bearing mineral (a copper-iron sulfide) that often looks brassy yellow and is the main source of mined copper worldwide. For investors, its presence and abundance in a rock deposit determine how much recoverable copper a mine can produce and how profitable extraction will be — think of chalcopyrite as the concentrated ingredient that makes an ore body valuable and worth developing.

bornite technical

"molybdenum + copper-rich chalcopyrite-bornite mineralization at depth"

Bornite is a common copper-bearing mineral that appears as metallic, often iridescent rock and is an important source of copper ore in mining. Investors care because the presence and concentration of bornite in a deposit affect how much copper can be economically extracted—similar to finding a larger bucket of usable metal in the ground—and therefore influence project value, production forecasts, and sensitivity to copper prices.

Calculated Vertical Gradient (CVG) Magnetics technical

"Attributes are overlain on imagery and Calculated Vertical Gradient (CVG) Magnetics."

Calculated vertical gradient (CVG) magnetics is a way of processing magnetic survey data to show how the Earth's magnetic field changes with depth, emphasizing subtle contrasts from buried rock bodies or structures. For investors, CVG maps help exploration teams pinpoint and rank potential mineral or resource targets more cheaply and quickly than blind drilling, reducing technical risk in early-stage projects much like using a metal detector to narrow where to dig.

VANCOUVER, BC / ACCESS Newswire / November 28, 2025 / Core Silver Corp. ("Core Silver" or the "Company") (CSE:CC)(FSE:8ZR)(OTCQB:CCOOF) is pleased to provide visuals showcasing representative porphyry copper-molybdenum-silver (Cu-Mo-Ag) mineralization intersected in drill hole LAV25-010, the first of four deep exploratory diamond drill holes completed during the 2025 season at the Laverdiere Copper Project (the "Project" or "Laverdiere"), located on the eastern Blue Property (the "Property") in the Atlin Mining District, northwestern British Columbia.

The Company's 2025 exploration program was designed to test the depth potential and continuity of a large (5 km x 8 km) multi-phase porphyry system through diamond drilling, structural mapping, and surface sampling. In total, seven (7) drill holes were completed across five (5) locations along the Valley Fault Zone, totalling 3,857 metres (Table 1).

LAV25-010 HIGHLIGHTS - CONFIRMATION OF A LARGE, ZONED PORPHYRY SYSTEM*

• LAV25-010 (the "hole") intersected zones of Cu-Mo-Ag mineralization and associated porphyry-style alteration from surface to over 675 metres drilled depth at the Valley Zone (Figure 1*).

• The hole was collared 1.8 kilometres southwest of previously drilled molybdenite-chalcopyrite-pyrite mineralization at North Adit (LAV22-006) and confirms the presence of a laterally and vertically zoned, multi-phase porphyry system extending to depth and linked to an exposed high-grade iron-copper-molybdenum-gold skarn occurrence (Figure 2).

• Observed alteration and mineralization styles are interpreted to represent marginal zones of a copper-molybdenum-silver rich ore body that remains open laterally and at depth.

• Drilling and structural mapping have now traced porphyry-style Cu-Mo-Ag±Au mineralization at Laverdiere for over 4.5 kilometres, from North Adit (Main Skarn Zone) to Lower Copper Creek, and across multiple east-west fault splays spanning more than 2.5 kilometres.

• The Laverdiere Copper Project represents a significant new porphyry discovery at the tip of the Stikine Terrane in an underexplored northern mineral district, effectively bridging the gap between British Columbia's Golden Triangle and Yukon's Tintina Gold Belt.
  
  *Assay results for all intervals described herein are pending, and visual estimates of mineral abundance should not be considered representative of grade.

Core Silver's President & CEO, Nick Rodway, commented:

"Drill hole LAV25-010 provides our clearest view yet into the scale of the porphyry system at Laverdiere. To see zones of impressive copper, molybdenum, and silver mineralization from surface to over 675 metres in our first deep hole is extremely encouraging. The visual evidence at Valley points to a large, multi-phase porphyry system that has the potential to evolve into a significant copper-silver-molybdenum system in the Atlin Mining Jurisdiction. We look forward to sharing additional visuals followed by assay results as they become available."

AN OVERVIEW OF DRILL HOLE LAV25-010

Drill hole LAV25-010, the first deep exploratory diamond drill hole completed at the Laverdiere Copper Project in 2025, was designed to test the depth extent and continuity of Cu-Mo-Ag mineralization associated with the Valley Fault Zone. This major structural corridor had previously returned surface assays of up to 366 g/t Ag, 0.71% Cu, and 0.54% Mo earlier in the 2025 season. The hole was drilled steeply to the northeast across the Valley Fault to a final depth of 703 metres (Figures 1 and 2).

From surface, LAV25-010 intersected a broad oxidized zone containing early quartz-vein hosted molybdenite and chalcopyrite mineralization (±pyrite ±bornite), locally overprinted by late silver-bearing sulfosalt and specular hematite-molybdenite veins and breccias. Epithermal quartz-carbonate veins are abundant throughout the upper section and appear to represent a later, mineralization-remobilizing overprint that partially modified earlier porphyry mineralization. Below the oxidized horizon, molybdenum mineralization persists with copper (chalcopyrite ±bornite), which becomes locally increasingly abundant, coarser-grained, and hosted in thicker vein sets with depth. This vertical zonation from silver-molybdenum-dominant mineralization near surface to molybdenum + copper-rich chalcopyrite-bornite mineralization at depth, is a characteristic of productive porphyry copper systems.

Specular hematite-bearing breccias also exhibit clear zonation, becoming progressively molybdenite ±tourmaline ±biotite-rich with depth. This mineralogical transition suggests the ore-forming fluids evolved from oxidized to reduced conditions and that the drillhole likely intersected a fertile portion of the Laverdiere Porphyry System.

The mineralogical and structural relationships observed in LAV25-010 confirm that the hole intersected the upper and marginal zones of a large, multi-phase Cu-Mo-Ag porphyry centre. Between zones of increased porphyry style alteration and mineralization at depth, late-to-post mineral phases of the Laverdiere Porphyry were encountered. The system remains open at depth and along strike.

ABOUT THE LAVERDIERE COPPER PROJECT

The Laverdiere Copper Project is a low-elevation, drill-permitted, early-stage high-grade Cu-Mo-Ag-Au porphyry-skarn Target. The Project has been sporadically explored since the early 1900s, without ever having received a significant exploration program. At Laverdiere, an extensive Cretaceous granodiorite intrusion hosts widespread Cu-Mo-Ag±Au porphyry mineralization. The intrusion is associated with a very high-grade Fe-Cu-Au-Ag massive sulphide skarn occurrence (the "Main Zone") that is exposed at surface along the western flank of the prolific Llewellyn Fault Zone (LFZ) at the porphyry-marble contact.

Adits driven into the Laverdiere area in the early 1900s reportedly returned up to 27m grading 1.20% Cu. The Llewellyn Fault Zone, a regional and strongly metal-endowed fault, cuts through the Laverdiere Copper Project for 14km of strike length and marks the contact between the Yukon-Tanana and Stikine Terranes in the Project area. Historic and shallow diamond drilling completed 125m north of the French Adit in 1974 reportedly returned 175m of 0.27% Cu, including 6m of 1.60% Cu and 7.8m of 1.60% Cu. Core Silver's inaugural diamond drilling campaign at the Laverdiere Copper Project in 2022 returned up to 48.5m of 0.90% Cu, 6g/t Ag, and 0.11g/t Au from 31.46m depth in drill hole LAV22-001 (French Adit), 223m of 0.11% Cu, 2g/t Ag, and 0.006% Mo from 15m depth in LAV22-002 (French Adit), and 107.38m of 0.11% Cu, 0.023% Mo, 0.9g/t Ag, and 0.02g/t Au from 144.62m depth in hole LAV22-006 (North Adit).

Drilled and mapped high-grade copper-bearing skarn mineralization at Laverdiere is coincident with embayments in the contact zones of the expansive Cretaceous intrusions on the west side of Hoboe Creek. A large unexplored embayment in the intrusion is mapped 8km to the south of the to-date explored zone at Laverdiere and is in contact with Boundary Range metamorphic rocks at this location. Apophyses of the larger granodiorite intrusion are also mapped in contact with limestone and marbles amenable to massive sulphide skarn mineralization approximately 7km to the southwest of the known zones of high-grade porphyry-skarn mineralization.

In 2024, high-grade porphyry Cu-Mo-Ag±Au mineralization at the newly defined Valley Zone, located 2.2km southwest of the Main Zone, was structurally mapped and sampled. At the Valley Zone, a series of sheeted mineralized porphyry veins and fractures hosted in altered granodiorite have been mapped and sampled over a 1-kilometer east-west trend following the Valley Fault that historically returned up to 3.24% Cu (with 82g/t Ag, 0.56g/t Au and 0.053% Mo) and 0.32% Mo (with 1.03% Cu, 4g/t Ag) in 2022. In 2024, a 20cm thick east-west striking quartz vein grading 0.83% Cu, 47g/t Ag, 0.44g/t Au and 0.007% Mo was discovered on the opposite side of the Valley Fault.

SAMPLING, PREPARATION & QA/QC

All 2025 rock and drill core samples were transported by helicopter at the end of each field day to the core logging facility in Atlin, BC for processing. Field samples were chosen to capture homogenous lithology, alteration, mineralization, and veining. All rock and drill core samples are submitted to Bureau Veritas (BV) Labs in Whitehorse, YT. For drill core, blanks and certified reference standard materials were inserted for every 20 core samples. Lab duplicate requests were inserted into the core sample sequence every 50 samples. Each rock and core sample is crushed to 70% passing 2mm, then pulverized to 85% passing 200-micron mesh. All samples then undergo a 4-Acid digestion with an ICP-MS finish for a 59-element ultra trace package (Method Code MA-250), as well as fire assay by Pb collection with ICP-ES finish for Au, Pt, and Pd (Method code FA-330). Samples that hit upper detection limits for elements of interest on the primary multi-element method are further analyzed via a secondary 4-Acid digest with an ICP-OES finish (Method Code MA-370). Extremely high-grade Pb samples were analyzed via a tertiary overlimit method, GC-817.

Soil samples collected in 2025 were also transported by helicopter at the end of each field day. Samples were photographed in the field and sample descriptions including sample number, location, elevation, color, saturation, depth of sample and soil horizon. Samples were dried in kraft sample bags on-site prior to being batched for shipment to BV Labs in Whitehorse, YT. There, each sample is dried at 60°C and sieved to pass -180 µm (80 mesh). All samples then undergo an aqua regia extraction with an ICP-ES/MS finish for a 36-element package (Method Code AQ200).

ABOUT CORE SILVER CORP.

Core Silver Corp. is a Canadian mineral exploration company focused on the acquisition and development of mineral projects in British Columbia, Canada. The Company currently holds 100% ownership in the Blue Property Mineral Tenure, which covers a land area of114,074 hectares (~1,140 km²). The project lies within the Atlin Mining District, a well-known gold mining camp located in the unceded territory of the Taku River Tlingit First Nation and the Carcross/Tagish First Nation. The Blue Property hosts a major structural feature known as The Llewellyn Fault Zone ("LFZ"). This structure is approximately 140km in length and runs from the Tally-Ho Shear Zone in the Yukon, south through the Blue Property to the Alaskan Panhandle Juneau Ice Sheet in the United States. Core Silver believes that the south Atlin Lake area and the LFZ has been neglected since the last major exploration campaigns in the 1980's. The LFZ plays an important role in mineralization of near surface metal occurrences across the Blue Property Mineral Tenure. The past 50 years have seen substantial advancements in the understanding of porphyry, skarn, and carbonate replacement type deposits both globally and in British Columbia's Golden Triangle. The Company has leveraged this information at the Blue Property Mineral Tenure to tailor an already proven exploration model and believes this could facilitate a major discovery. Core Silver is excited to become one of Atlin Mining District's premier explorers where its team believes there are substantial opportunities for new discoveries and development in the area.
