stocks issues news for silver stock Rio Silver Inc. (TSX-V: RYO
| OTC: RYOOF) ,
Rio Silver Inc. (“Rio Silver” or the
“Company”) (TSX-V: RYO | OTC: RYOOF) is commencing the
regulatory process required to enable physical access at its Maria
Norte Project, formally engaging Peru’s Ministry of Energy and
Mines (Ministerio de Energía y Minas, MEM) through its General
Directorate of Mining (DGM), alongside the National Superintendency
for the Control of Weapons and Explosives for Civilian Use (SUCAMEC).
Together, the Company’s established exploration and exploitation
access agreements , combined with the advancement of required permits
and ongoing coordination with the president of the local community,
constitute the regulatory and social steps required to access exposed
surface mineralization, prepare portal access, and support a staged
transition underground along the mineralized structures.
From Visually Exposed Surface Veins to Planned Underground Access
At Maria Norte, high-grade silver mineralization has been visually
confirmed at surface, providing clear and direct targets for planned
initial access. Blasting and explosive permits are required to safely
break rock, access these exposed veins, and prepare portal entry ahead
of any underground advancement.
The permitting process in Peru involves sequential approvals,
including:
Mining activity authorization with the Ministry of Energy and Mines
(MEM)
Explosives use permit issued by SUCAMEC
Explosives purchase authorization issued by SUCAMEC
Under standard regulatory timelines, this permitting process typically
requires several months to complete. Based on current engagement and
procedural progress, the Company expects to receive the required
permits during Q2, subject to regulatory review.
Once permits are received and initial access is established, future
exploration planning is expected to focus on evaluating strike
continuity and depth potential for long term exploitation.
Management Commentary
“Maria Norte is a rare development opportunity where
high-grade silver veins are already exposed at surface, allowing us
to move directly into execution once access is authorized,”
said Chris Verrico, President and Chief Executive Officer of Rio
Silver. “In today’s silver market, that is increasingly
uncommon. Most new silver supply globally comes as a by-product of
base-metal mining, whereas Maria Norte is a silver-dominant system
— something of a unicorn in the current development landscape.
We are pursuing the permits that are the regulatory gateway that
allows us to safely access visible mineralization, prepare
underground entry, and begin converting high-grade silver into
mineable tonnes through a disciplined, capital-efficient
approach.”
High-Grade Silver Confirmed by Verification Sampling
As part of the independent National Instrument 43-101 review,
verification sampling was conducted by James A. McCrea, P.Geo., the
independent author of the NI 43-101 Technical Report, during a site
visit to the Maria Norte Project in June 2025. Sampling targeted
surface vein exposures and historic waste material and returned
high-grade silver values, including:
869 g/t silver, with associated lead and zinc, from a 0.5-metre
surface vein channel sample
991 g/t silver from a 0.7-metre surface vein channel sample
396 g/t silver from a historic waste dump grab sample

Table 1: Maria Norte Verification Sampling Results (NI 43-101)*
*Verification sampling returned silver values ranging from 396 g/t Ag
to 991 g/t Ag, with associated lead, zinc, and localized gold values.
These results confirm the presence of high-grade silver mineralization
at surface, consistent with historical sampling by previous operators
and characteristic of low-sulphidation epithermal vein systems common
to the Huachocolpa District.
A total of four (4) verification samples were collected, consisting of
three (3) chip samples from surface vein outcrops and one (1) grab
sample from a historic waste dump, with chip sample widths ranging
from approximately 0.4 metres to 0.7 metres. All samples were bagged,
labelled, and sealed in the field using single-use security ties,
transported by the author to Lima, Peru, and analyzed by Certimin
S.A., an ISO 9001–certified laboratory located in the Santiago
de Surco municipality of Lima.
No additional quality control samples (blanks, standards, or
duplicates) were inserted due to the limited number of samples
collected, which the author considered appropriate for the exploration
stage of the project. James A. McCrea, P.Geo. concluded that the
sampling methods, sample handling, preparation, and analytical
procedures are adequate for data verification purposes, and that the
results are representative of the surface mineralization observed at
Maria Norte.
What’s Next
Continued coordination with MEM and SUCAMEC to secure the necessary
permit approvals
Preparation for controlled access to surface-exposed mineralization
upon permit receipt
Portal access preparation to support staged underground entry
Ongoing metallurgical validation to support toll milling and
capital-efficient processing
Why This Matters to Investors
For investors, securing necessary permits represents a critical step.
This marks the transition from confirmed surface mineralization to
physical rock movement and site access. At Maria Norte, where
high-grade silver is already visible at surface, receipt of approvals
materially reduces execution risk. Combined with a capital-light,
toll-milling strategy and a silver-dominant system in a market where
most silver is produced as a by-product, Maria Norte is positioned to
advance efficiently toward near-term value creation. In a strong
silver price environment, projects capable of moving decisively from
exposure to execution are increasingly scarce and command outsized
market attention.
