Demesne Resources Ltd. Confirms Underground Access to

Tungsten Vein System, IMA Mine Project in Idaho, USA

- NOT FOR DISSEMINATION IN THE UNITED STATES OR THROUGH U.S.

NEWSWIRE SERVICES –

● Demesne completes initial assessment of the condition of underground workings in the

IMA Mine

● Tungsten vein systems readily accessible in upper levels of the historical mine

Vancouver, BC, December 17, 2024 – Demesne Resources Ltd. (CSE:DEME)

(OTCQB:DEMRF) (FSE:RK9) (“Demesne” or the “ Company”) is pleased to announce that

contract staff have successfully accessed the IMA tungsten vein system through the upper level of

the historical IMA Mine.

“Direct access the vein system underground is a significant benefi t to the project and really puts

us ahead on the development timeline.” said Murray Nye, CEO of Demesne “This will allow

Demesne to confirm prior unde rground sampling and development work completed by past

operators and collect bulk samples for gravity separation test work.”

The IMA Mine is a past produc ing underground tungsten mine s ituated on 22 patented claims

located in East Central Idaho. Between 1945 and 1957, the property pr oduced approximately

199,449 MTUs of WO3 and was subsequently explored for molybdenum and tungsten by various

operators between 1960-20081.

Between 1978 and 1982, Inspiration Developm ent Corporation focused exploration on

development of the quar tz-tungsten-vein system, rehabilita ting upper levels of the mine to

complete underground resource delineation drilling, and conducting metallurgical work.

Inspiration planned a 300 tpd underground operation using inclined slot methods targeting the vein

systems in the upper levels of the IMA Mine. Inspir ation planned to direct ship ore to a mill in

Phillipsburg, MT for processing. Development work ceased in 1982 prior to recommencement of

mining associated with a decrease in tungsten prices2.

On December 10 th, Demesne staff entered the undergroun d mine on the upper D level, in an

approximately 7x7 ft access drift which had been re habilitated in the 1980s 3. Ground conditions

were excellent with minimal ground support observed. There was good natural ventilation and no

underground water inflows were seen. The princi pal veins (No 5 and 7 veins) are well exposed

and vary in width from 3 ft to over 10 feet wide with strike length of at least 400’ on the D level.

The veins consist of quartz w ith variable assemblages incl uding pyrite, fluorite, hubnerite,

scheelite, tetrahedrite, galena, s phalerite and chalcopyrite. Limited areas of the vein system had

been partially stoped both above and below the level, but veins are un-mined over hundreds of feet

along strike as observed within the drifts.

The Company plans to continue work to digitize and verify historical information and records in

support of developing a 43-101 co mpliant Mineral Resource for the IMA Mine, in conjunction

with initiating project planning and trade off studies, and planning for sample collection activities

for verification and metallurgical studies.
