Rumble Resources Announces Permit Application Submitted

for the Wilmac Copper-Gold Project in Southeastern British

Columbia

Vancouver, British Columbia--(August 19, 2025) - RUMBLE RESOURCES INC. (CSE: RB)

(the "Company" or " Rumble"), is pleased to announce that a Notice of Work (NOW) Permit

Application has been submitted for an Induced Polarization / Audio Magnetotelluric (IP/AMT)

ground geophysical survey on the W ilmac Copper-Gold Property (the “ Wilmac Project ”, the

“Property”, or “ WILMAC”). The Company is currently earning up to a 70% interest in the

Property, subject to a 2% net smelter return royalty (see June 11, 2025 News Release).

The Wilmac Project is located in south -central British Columbia, southwest of Princeton and

approximately 10 kilometres west of Hudbay Mineral Inc.’s currently producing Copper Mountain

Mine that hosts a NI 43-101 Proven and Probable Mineral Reserve of 346 million tonnes grading

0.245% copper (plus gold and silver by-product credits).

The Property is interpreted to host potential for identification of one or more copper-gold alkalic

porphyry occurrences similar in age and deposit type to those hosting the Copper Mountain mine.

The Property comprises two mineral tenures totaling approximately 2,355 hectares (5,819 acres)

in a well-documented and prolific copper-gold porphyry belt.

The proposed IP/AMT survey will be centred on three previously excavated trenches comprising

the WILMAC MINFILE occurrence (092HSE042). The survey will consist of six east-west lines

between 1.4 and 3 km in length and spaced 300 metres apart. The NOW (Notice of Work) Permit

Application is expected to receive a “No Permit Required” authorization, given the minimal

surface disturbance involved, with the proposed survey to be completed in the fall of 2025.

The WILMAC MINFILE occurrence covers a series of three northwest – southeast oriented

trenches, extending approximately 85 metres from east to west, previously excavated in

predominantly coarse-grained to pegmatitic hornblendite . The trenches are up to 70 m etres in

length, with the resulting mineralization exposed over an area of approximately 0.50 h ectares.

Excavated mineralized material is present at the southern ends of the western and middle trenches,

with in situ mineralized material exposed locally in the floor and walls of these trenches.

Excavated material at the southe rn ends of the middle and western trenches includes abundant

epidote altered and chalcopyrite mineralized material. Epidote alteration is present as selective

replacement of primary phenocrysts, patchy alteration of the matrix and as epidote veins. Sulphides

are present as both pyrite and, to a slightly lesser degree, chalcopyrite, predominantly hosted within

quartz-carbonate veins and weakly to moderately devel oped stockworks. Several instances of

possible AB porphyry-style veins (quartz-carbonate veins having sulphide cores) were noted.

In 2023 and 2024, a total of nine grab samples were taken of well -mineralized material from

exposures within and/or immediately adjacent to the trenches and from excavated material at the

southern ends. Analytical results for copper from the se samples were anomalous and very

encouraging, ranging between 200 ppm and two values in excess of 1% (1.235 % and 1.670%).

The average of the nine samples taken was 6,390 ppm or 0.639% copper.

In addition to well-mineralized material exposed by the trenches at the WILMAC occurrence, two

small exposures of diorite and/or ultramafic previously mapped along the Lamont Ridge Forest

Service Road will also be covered, in whole or in part, by the proposed survey.

Woodruff Creek Option

The Company further announces that it has been unable to renegotiate the option agreement terms

with respect to the Woodruff Creek property to its satisfaction and has decided to terminate the

option. Rumble will focus its efforts on the exploration of the Wilmac Project.

Share Split

Rumble is also pleased to announce that it is undertaking a forward split of all of its issued and

outstanding common shares (the "Common Shares") on the basis of two new Common Shares for

one old Common Share (the "Forward Split"). All shareholders of record on August 26, 2025 (the

“Record Date”) will be entitled to receive one additional Common Share for each Common Share

held at the close of the trading day (the "Record Date"). The Company is undertaking the Forward

Split to increase the liquidity and marketability of the Common Shares.

As per Canadian Securities Exchange ("CSE") policy, the Forward Split will be conducted on a

"push-out" basis and therefore the CUSIP number and trading symbol for the Common Shares will

remain unchanged. DRS statements for the additional one Common Share resulting from the

Forward Split will be sent to the shareholders as of the Record Date by the Company's Transfer

Agent, Odyssey Trust Company. Shareholders of the Company do not need to take any action with

respect to the Forward Split. The Forward Split will not materially affect the percentage ownership

in the Company of shareholders even though such ownership will be represented by a larger

number of Common Shares.

The Company currently has 17,427,000 Common Shares issued and outstanding. Upon completion

of the Forward Split, the Company will have approximately 34,854,000 Common Shares

outstanding. The Forward Split remains subject to the approval of the CSE.

Outstanding stock options and share purchase warrants will also be adjusted by the Forward Split

ratio and the respective exercise prices of outstanding stock options and share purchase warrants

will be adjusted accordingly.
