GPS Commences Drilling Program at Everton, Victoria

Vancouver, BC, Canada - Monday, March 2nd, 2026 - Great Plains Metals Corp. ("GPS" or

"the Company", TSX-V: GPS, Frankfurt Exchange: 8VC) is pleased to provide an update

regarding the drilling program at the Everton Project in Victoria (Figure 1).

Highlights:

● Re-evaluation of legacy data including mine records, identified walk-up drill

targets at the former Everton Molybdenum mine.

● Recent detailed geological mapping identified previously unrecognized

cupolas with textures typical of those observed in Pencil Porphyries.

● Landowner access agreements were finalized late in 2025 and diamond

drilling has commenced to evaluate outcropping molybdenum

mineralization.

Re-evaluation of legacy mining records and exploration conducted during the 1970’s data

has identified a number of walk-up drill targets within the former open cut workings at

historic Everton molybdenite mine which are interpreted to represent the uppermost

section of a mineralized pencil porphyry system. Previous mining was centered on two

cupolas with distinctive unidirectional solidification textures (USTs) with disseminated

molybdenite mineralization observed in outcrops and at the mine dumps (Figure 2). A first

pass shallow diamond drill campaign comprising a minimum of five holes has

commenced, and further updates will be provided as the drilling progresses. Assays are

anticipated to be received in Q2.

The Everton Molybdenum Mine

Approximately 20,000T @ 1.4% Mo was mined at Everton during the period 1918-1926

from open cut and shallow underground workings Only limited previous exploration has

been conducted since that time, mostly 40 years ago. It was also Australia’s highest-

grade molybdenum mine. Everton is strategically located at the southern extension of the

Lachlan Fold Belt where numerous porphyry-related deposits are currently being actively

explored.

Molybdenum (Mo), is a silver-grey transition metal renowned for having one of the highest

melting points of any element. Because it resists softening or expanding at extreme

temperatures, it is classified as a refractory metal and is indispensable in high-stress

industrial applications. It is also one of the critical elements and is currently trading around

US$27 per pound.

Aidan Bishop, CEO, commented:

“The presence of rocks displaying unidirectional solidification textures (USTs) indicates

the tops of unrecognized pencil porphyries (figure 2). The exciting aspect about Everton

is that the pencil porphyries are exposed at the surface (figure 3). Others may be present

nearby under cover. The focus of the current drill program will be to delineate the

geometry and size of the system and determine the intensity of mineralization. The

Everton project is a great example of the Company’s rapid discovery model for low-cost

exploration across a portfolio of drill ready projects”
