Announces Expanded Drill Plan

Vancouver, British Columbia TheNewswire – September 29th, 2025 Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to report that it has received final assay results including overlimits for the first batch of twenty-three samples taken at the Silver King project located in Arizona. The new assays include 619 gt Ag and 511 gt Ag for two samples taken at the Silver King shaft area, as well as 757 gt Ag, 1.5% Cu, 6.7% Pb, and 11.5% Zn for the recently encountered polymetallic vein.  Preliminary assay data was described in a news release dated September 24, 2025.

‘The overlimit assays for silver highlight the high-grade nature of both the mineralization around the Silver King mine and the recently encountered polymetallic vein. The results confirm the significance of the recently discovered polymetallic vein as a new exploration target at the Silver King project,’ said Dr. Craig Gibson, Chief Exploration Officer. ‘Overlimit copper assays ranging from 1.11% to 2.43% copper for three samples from the replacement mineralization area provides encouraging data for this style of mineralization. The replacement mineralization occurs along strike with the stratigraphic horizon at the nearby Magma mine and occurs as a large body on the Black Diamond claim.’

Drill Program Update

Prior to the discovery of the mineralized veins and porphyry related style mineralization announced recently, Prismo had planned a drill program at the historic Silver King mine for about 1,000 meters. That drill plan was designed to test the upper half of the steeply dipping pipelike Silver King mineralized body as well as potential mineralization adjacent to the dense stockwork that was the focus of historic mining.

Following the recent discoveries, Prismo is planning to add second phase of drilling for an additional 1,000 meters. This additional program will focus on the newly identified targets outside of the historic mining area, such as the polymetallic vein and the copper vein mentioned above. Drilling of a large body of replacement mineralization on the patented Black Diamond claim is also being planned and is road accessible on private ground.

‘Much of the focus of the exploration program to date has consisted of a property-wide survey of historic mines and prospects surrounding the direct Silver King workings,’ said Gordon Aldcorn, President of Prismo. ‘ This work has expanded our geological thinking and resulted in the recognition of several new types of mineralization at the project, providing additional targets for exploration. Prismo has already submitted a plan of operations for the drill program with Forest Services. Some of the drilling sites considered for the new targets will be subject to further permitting applications.’

Standard Uranium Ltd. (TSXV: STND,OTC:STTDF) (OTCQB: STTDF) (FSE: 9SU0) (‘Standard Uranium’ or the ‘Company’) is pleased to announce that it has signed a definitive property option agreement (the ‘Option Agreement’), dated September 26, 2025, with Collective Metals Inc. (CSE: COMT) (the ‘Optionee’), an arms-length party. Pursuant to the Option Agreement, the Optionee has been granted the option (the ‘Option’) to acquire a seventy-five percent interest in the 4,002-hectare Rocas Project (‘Rocas’ or the ‘Project’) located in the eastern Athabasca Basin region (Figure 1).

Rocas Project Highlights:

• Prime Location – More than 7.5 km of exploration strike length along a strong NE-SW magnetic low trend coincident with EM conductors and cross-cutting faults, providing shallow drill targets south of Key Lake.
• Uranium at Surface – Mineralized outcrop grab samples along approximately 900 metres of strike length, grading up to 0.5 wt.% U₃O₈ and never drill tested¹ (Figure 2).
• New Uranium Targets – Results from a high-resolution ground gravity survey completed in 2024 highlight potential alteration halos and high-priority exploration targets along well defined structural corridors.

Sean Hillacre, Standard Uranium President and VP Exploration, stated: ‘We are very pleased to have executed the Rocas Option deal with our new partners at Collective Metals quickly, allowing our team to get boots on the ground before the snow flies in Saskatchewan. This inaugural program will allow us to build a comprehensive understanding of the geology across Rocas prior to a maiden drill program, in addition to ground-truthing historic uranium occurrences through scintillometer prospecting and re-sampling.’

About the Rocas Project

The Rocas project comprises 4,002 hectares, located 75 kilometers southwest of the Key Lake Mine and Mill facilities along Highway 914, and approximately 72 kilometers south of the present-day margin of the Athabasca Basin. The project was acquired via staking in May 2023 and recently expanded by an additional 931 hectares. Standard Uranium holds a 100%-interest in the Property.

The Project covers 7.5 kilometres of a northeast trending magnetic low/electromagnetic (‘EM’) conductor corridor which hosts several uranium showings, including historical mineralized outcrop grab samples along approximately 900 metres of strike length, grading up to 0.5 wt.% U₃O₈¹. Notably, none of the historical uranium occurrences have been drill-tested.

Historical airborne EM work in 2017 defined conductive trends on the Project west of and sub-parallel to the Key Lake Road shear zone, corresponding with favourable metasedimentary basement lithologies. Multiple parallel conductors, offsets, and termination points indicate the trend widening and potential cross-cutting structures. Additionally, a 2007 field sampling program identified anomalous lakebed geochemical anomalies that statistically rank as greater than 95^th percentile U, Co, V, and Zn along the conductor corridor, including high U/Th ratios².

Exploration Plans

The Company’s technical team will mobilize to the Rocas Project on September 30^th, 2025, to undertake a detailed mapping, prospecting, and sampling program to ground-truth historical uranium showings at surface. Collected grab samples will be transported to Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, SK for geochemical analysis.

In 2024, the Company contracted MWH Geo-Surveys (Canada) Ltd. to complete a high-resolution ground gravity survey along known conductive exploration trends on the Rocas project. The survey was designed to aid in the identification of potential zones of hydrothermal alteration of host rocks associated with uranium mineralization events.

Multiple new drill target zones have been identified on the Rocas project, outlined via the confluence of low gravity anomalies, historical surface mineralization, lakebed geochemical anomalies, EM conductors, and crosscutting fault zones.

Ongoing geophysical interpretation and modeling is planned throughout 2025 to integrate historical results with newly collected datasets, which will provide high-priority drill targets and significantly derisk the Project prior to modern drilling next year.

The Company believes the Project is highly prospective for the discovery of shallow, high-grade* basement-hosted uranium mineralization. Located south of the current margin of the Athabasca Basin, Rocas boasts shallow drill targets with bedrock under minimal cover of glacial till.

3-Year Earn-In Option

The Option is exercisable by the Optionee completing cash payments and share issuances, and incurring the following exploration expenditures on the Project:

Notes:
⁽¹⁾Issuable at a deemed price equivalent to the last closing price of the common shares of the Optionee on the Canadian Securities Exchange immediately prior to entering into the Option Agreement.
⁽²⁾Issuable at a deemed price equivalent to the volume-weighted average closing price of the common shares of the Optionee on the Canadian Securities Exchange in the thirty (30) trading days immediately prior to issuance.
⁽³⁾Subject to an eighteen (18) month escrow, with three (3) equal releases on the six (6), twelve (12) and eighteen (18) month anniversaries of issuance.
⁽⁴⁾Subject to a twelve (12) month escrow, with two (2) equal releases on the six (6) and twelve (12) month anniversaries of issuance.

Prior to exercise of the Option, the Company will act as the operator of the Project and will be entitled to charge a 10% fee on expenditures in Year 1, increasing to 12% in Year 2 and Year 3.

About Standard Uranium (TSXV: STND,OTC:STTDF)

We find the fuel to power a clean energy future

Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in the world’s richest uranium district. The Company holds interest in over 235,435 acres (95,277 hectares) in the world-class Athabasca Basin in Saskatchewan, Canada. Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.

Standard Uranium’s Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises ten mineral claims over 30,737 hectares. Davidson River is highly prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries. However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.

Standard Uranium’s eastern Athabasca projects comprise over 43,185 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.

Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.

VVC Exploration Corporation, dba VVC Resources (‘VVC’ or the ‘Company’) (TSX-V: VVC; OTC: VVCVF) today announces its strategic development of the Central Kansas Uplift (‘CKU’) Project, an initiative being advanced through VVC’s wholly owned subsidiary, Plateau Helium Corporation (‘PHC’). The CKU Project targets helium-rich natural gas within multiple stacked reservoirs in Rush and Pawnee Counties, Kansas, where PHC has assembled a meaningful lease position and identified multiple well development locations. The CKU Project is a very mature exploration area with thousands of historic wells drilled. These wells provide a tremendous volume of geologic, engineering, and production data that is used to guide and de-risk PHC’s development plans.

The project overlies the Central Kansas Uplift, an area with historical helium concentrations ranging from 1.5%–6%. Geologically, there are areas within the CKU that consist of up to eight stacked helium-rich reservoir zones with typical well depths of 2,500–5,000 feet. The Company has leased 10,875 acres of an area of interest (AOI). The AOI has 160 potential drilling locations. The CKU area provides existing midstream infrastructure as evidenced by multiple gas pipelines, processing facilities and a helium liquefier that are all located within PHC’s AOI.

‘In CKU, we are aligning subsurface opportunities with existing midstream access,’ said Chairman Terrence Martell, Ph. D. ‘The combination of stacked zones, documented helium in historic gas and oil wells, and existing pipelines provides a practical pathway to add wells methodically while managing capital intensity.’

Development is planned in phases that prioritize additional wells and processing access, while evaluating further lease expansion within the CKU fairway.
