**Exhibit 99.1**

**FORM 51-102F3<br> MATERIAL CHANGE REPORT**

**Item 1.** **<u>Name and Address of Company</u>**

Collective Mining Ltd. (the "**Company**")

82 Richmond St. East

Toronto, Ontario M5C 1P1

**Item 2.** **<u>Dates of Material Change</u>**

March 11, 2026

**Item 3.** **<u>Press Releases</u>**

News release in respect of the material change referred to in this report was disseminated through the facilities of Canada NewsWire on March 11, 2026. The news release was subsequently filed on SEDAR+.

**Item 4.** **<u>Summary of Material Change</u>**

On March 11, 2026, the Company entered into a binding promise of sale and purchase agreement with certain arms-length vendors in connection with the acquisition of the remaining surface rights required for future mining operations at the Corporation's Guayabales Project in Caldas, Colombia (the "**Guayabales Surface Rights Agreement**") for total aggregate consideration of US$34 million in cash.

**Item 5.** **<u>Full Description of Material Change</u>**

On March 11, 2026, the Company entered into the Guayabales Surface Rights Agreement pursuant to which it agreed to acquire the remaining surface rights required for future mining operations at the Corporation's Guayabales Project in Caldas, Colombia. The Company also holds the mineral titles, or options to acquire the mineral titles, over all areas where surface titles have been, or are being acquired for future mine development.

Under the terms of the Guayabales Surface Rights Agreement, the Company agreed to acquire land for a total purchase price of US$34 million in cash, to be paid in installments over a five-year period as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) an aggregate of US$6.4 million to be paid in two instalments in 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) an aggregate of US$7.8 million to be paid in two installments in 2027;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) an aggregate of US$6.4 million to be paid in two instalments in 2028;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) an aggregate of US$6.4 million to be paid in two instalments in 2029; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) an aggregate of US$6.4 million to be paid in two instalments in 2026.

Payments beginning in 2028 are also subject to additional annual accrued interest payment of 6.0%, and in the event that the Company receives approval from the relevant environmental agency in Colombia for a mining operation and elects to begin construction prior to paying the final cash installments under the Guayabales Surface Rights Agreement, certain outstanding installment payments will become immediately due prior to the commencement of major mine construction activities.

With all the surface titles required for a future mine now either owned or under agreement, the Company plans to commence construction of an exploration adit in the fourth quarter of 2026. The exploration adit, which is proposed to be used to support the Company's geological understanding of the Guayabales Project from an underground vantage, will initially be used to construct underground drill chambers to test the Company's Trap system. With underground access, the Company expects to be able to advance Trap's exploration potential in an expedited manner.
