APGOF) Announces 2026 Exploration and Development Program for its U.S. based Calico Project

Advancing one of the largest undeveloped primary silver assets in the
U.S. in a rising silver and critical minerals market.

(www.investorideas.com
Newswire) – Investorideas.com reports breaking silver stock
news – Apollo Silver Corp. (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF0) is pleased to
announce details of its 2026 Exploration and Project Development
Program (the “2026 Program”) at the Company’s Calico
Silver Project (“Calico” or the “Project”)
located in San Bernardino County, California. The 2026 Program is
designed to advance both the exploration potential and project
development initiatives at Calico at a time when the silver market
sentiment is strengthening and the metal’s recent designation as
a U.S. critical mineral is drawing renewed attention to secure
domestic supply. As one of the largest undeveloped primary silver
assets in the U.S., Calico is well positioned within this evolving
landscape.

The 2026 Program advances prospective exploration and project
development at Calico in support of longer-term planning for
processing, mine design, and permitting. Project development
activities will focus on metallurgical studies, geotechnical work, and
the initiation of development-stage permitting, and will include a
drilling program designed to provide material for geotechnical
analysis and metallurgical testing. Planned exploration activities
include exploration drilling, property-scale mapping and sampling, and
both airborne and ground geophysical surveys.

Highlights of the 2026 Program:

Project Development Activities

4,500 meter (“m”) HQ large diameter core drill program
commencing in Q1 2026 to address current on-going metallurgical
studies and geotechnical analysis to support future mine design work.

A metallurgical test work program focused on evaluating processing
options and investigating opportunities to improve upon historic
silver recoveries.

Early-stage permitting activities, including the initiation of long
term, on-going baseline environmental monitoring, ensuring that the
regulatory phase progress aligns with technical advancements.

Exploration Activities

1,000 m NQ diameter exploration drilling program at the Waterloo
Property (“Waterloo”) to test the Burcham gold potential
with the goal of expanding the gold resource.

Ground and airborne geophysical surveys including gravity, Induced
Polarization (“IP”), and magnetics to image and
characterize subsurface controls of mineralization as well as
lithological, structural and alteration features at both a deposit and
property scale, to assist in defining and prioritizing future drill
targets.

Expanded geological mapping across Waterloo and Mule Property
(“Mule”) to advance surficial geological interpretations
and promote target generation.

“Our 2026 Program positions Apollo Silver to advance Calico at
an opportune moment,”

said Ross McElroy, President and CEO of Apollo Silver.

“Silver’s addition to the U.S. critical minerals list
and the current strength in precious-metal markets highlight the
importance of responsibly developing domestic supply. Calico hosts
one of the largest undeveloped primary silver deposits in the United
States. The exploration program will allow us to evaluate the
blue-sky potential of the Project, while the planned metallurgical,
geotechnical, and geophysical work will further strengthen our
technical understanding and support the next stages of its
advancement.”

2026 Project Development Program

The 2026 project development program at Waterloo includes a 4,500 m HQ
diameter core drill program aimed at obtaining sufficient material and
data for on-going geotechnical and metallurgical analysis, and the
initiation of development level permitting activities. The permitting
activities will begin in 2026 and will form the foundational start of
a long-term permitting process, which is designed to keep the
regulatory progress aligned with technical advancement.

Core Drilling – Waterloo (Geotechnical & Metallurgical)

A 4,500 m HQ diameter core drilling program is scheduled to begin in
mid-Q1 and continue through Q2 2026. Drill core will be used for:

• Geotechnical data collection for analysis to support engineering
  and mine design; and

• Metallurgical test work to better characterize the silver recovery
  and evaluate opportunities for recovery enhancement.

Metallurgical Studies

Metallurgical test work will continue throughout 2026 and will focus
on:

• Evaluating ore characteristics and processing options; and

• Assessing opportunities to improve silver recoveries above
  historical levels identified, presently estimated at ~65%.

Underground Volume Survey

Calico is host to numerous historic small-scale, high-grade vein
hosted mining operations that were active from ~1880 to 1894, some in
close proximity to the Waterloo and Langtry deposits. A LiDAR survey
of historical underground drifts and tunnels at Waterloo is planned
for Q4 2026 to enhance the knowledge of precise location and scale of
historic workings with respect to the current day deposits. This
information should provide important data to assist with improved
resource classification, as well as provide critical information for
future mine development.

2026 Exploration Program

The 2026 exploration program at Calico includes core drilling,
geological mapping, ground gravity and IP surveys, and airborne
magnetics geophysical surveys, all designed to map geological features
and interpret controls of mineralization at both a deposit and
property scale across the Waterloo and Mule properties. Results will
be used to assist in generating future drill targets.

Exploration Drilling

The Company plans to complete 1,000 m of NQ diameter core drilling to
test the Burcham gold target located on the east side of Waterloo, in
the area of the historical Burcham Mine. The work is scheduled for
Q1–Q2 2026 and is designed to evaluate the potential for
expansion of the existing gold resource.

Geological Mapping

Geological mapping will continue throughout 2026, and work will
include:

• Updating surficial geological interpretations at both Waterloo and
  Mule;

• Follow-up ground assessment of anomalies identified from the 2022
  IP geophysical survey on Waterloo; and

• Ongoing support for exploration targeting and drill planning.

Geophysics

A multi-method geophysical program is planned for Q1, Q2 and Q4 2026.
Surveys will include both airborne and ground surveys which will
assist to resolve the subsurface interpretations and potentially help
define and prioritize targets for future drilling. Activities will
include:

• Ground Gravity and Subsurface Historical Mine Workings surveys at
  Waterloo;

• IP and airborne magnetic surveys at Waterloo and Mule; and

• Integration and interpretation of new and historic geophysical
  datasets (Gravity, IP, Magnetics).

Laboratory Analysis

Petrographic studies and soil/rock assays will run through Q1 to Q3
2026 which will support geological mapping and aid in drill target
refinement.
