Form 51-102F3 Material Change Report Item 1. Name and Address of Company Goldplay Mining Inc. (the “ Company ”) Suite 650 – 1021 West Hastings St. Vancouver, BC V6E 0C3 Telephone: (604) 655 1420 Item 2. Date of Material Change March 1, 2021. Item 3. News Release The news release announcing the material change has been issued at Vancouver, British Columbia on March 1, 2021, was disseminated via Accesswire and was subsequently filed on SEDAR. Item 4. Summary of Material Change Goldplay Mining Inc. (or the “Company”), has announced that it has signed a definitive agreement with European Electric Metals Inc. (“EVX”) whereby Goldplay acquired an initial 70% equity interest in EVX Portugal (an EVX subsidiary), a private Portugal based company, which has the legal rights to an exploration licence application with the Government of Portugal to the Borba 2 exploration property. The Company also announced that it has issued additional stock options to some of the directors and consultants of the Company and that it has appointed Jose Mario Castelo Branco as the Exploration Manager of the Company. Item 5. Full Description of Material Change 1) Borba 2 property in Portugal

The Company acquired an initial 70% equity interest in EVX Portugal (an EVX subsidiary), a private Portugal based company, that has the legal rights to an exploration licence application with the Portugal Government to the Borba 2 exploration property (the “Exploration Application” or “Borba 2”), covering approximately 230 square kilometres in the Alentejo region in Southern Portugal. The Exploration Application is in the final stages of being finalized with the Portugal government. The Exploration Application is not granted yet and there are no guarantees that it will be granted.

The Exploration Application has a well-documented potential to host precious and base metals mineralization often enhanced by the presence of abundant Au and /or Cu mineral occurrences in shear zones and in epithermal systems associated with intra-Ordovician volcanics. The Exploration Application includes a total of four separate projects including three past producing mines that covers an area of 230 square kilometers as follows.

- (i) Miguel Vacas Past Producing Copper Mine

The copper mine last operated in 1986 and has produced at an average grade of 1.2-1.4% Cu. Historical near surface drilling (60 to 71.63m) intercepted 1.79 % Cu over 10.54m including 2.29% Cu over 7.30 m.

A historical non-compliant in-house resource estimation was completed by Rio Narcea in 2007 based on 20 historical holes and estimated:

• Oxide ore (from 0 to 80m depth): 1.2 Mt @ 1.23% Cu.

• Sulphide ore (from 80m to 250m): 4.4 Mt @ 1.24% Cu

The project remains open for exploration.

The readers should not rely on any historical estimates. The Company and the QP has not done sufficient work to classify historical estimate as a current resource. Company is not treating the historical estimate as a current resource. Additional work including drilling will be required to verify and upgrade historical estimates.

(ii) Mostardeira Copper-Gold Mine

This Cu-Au mine area, located approximately 2 km south of the town of Estremoz represents a wide WSW-ESE shear zone that is developed for at least 700 m along strike and is open into both directions. This shear zone has been historically mined for Cu with most of the mining works concentrated along a thin high-grade Cu zone (<2m) averaging over 5% Cu.

Mineralization is hosted by Silurian and Devonian metasediments. Channel sampling by Rio Narcea (2006) has intercepted the following mineralized intervals: 2.60m grading 4.15 g/t Au, 0.40% Cu including 0.60m grading 11.20 g/t Au and 0.65 % Cu and another 3.60m interval grading 2.40 g/t Au, 0.82 % Cu and 80 g/t Ag. The average grade for the total of 34 samples analysed was 1.54 g/t Au, 22 g/t Ag and 0.25% Cu with a maximum of 11.20 g/t Au and a minimum of 0.10 g/t Au.

The project is open for exploration.

(iii) Bugalho Copper-Gold Mine

Dump samples of silicified and sheared acid tuffs from the Bugalho mine area assay up to 10.97 g/t Au, 5.36% Cu and 20 g/t Ag.

Mineralization can be mapped about 5 km along strike and includes three main veins up to 1.3m thick within a several meter wide shear zone.

The project is open for exploration

(iv) Almagreira Gold Prospect

This area Drilling has been identified by Rio Tinto during the early eighties and limited trenching and drilling have indicated the presence of gold mineralization associated with clay-sericite-silica alteration zones associated with a ENE-WSW fracture zone and

represents an epithermal system identified in this sector hosted by brecciated acid volcanics and dolomites.

Historical drilling intercepted an interval of 5.45 m grading 1.53 g/t Au, including 2.47m grading 2.44 g/t Au from hole PAM-01. The highest individual value obtained came from a gossanous quartz-dolomite altered marble grading 5.77 g/t Au over an intercept of 0.75m. Hole Pam-02 intercepted an interval of 2m grading 3.7 g/t Au. The mineralized zone coincides with sections of intense silica-carbonate alteration with several massive gossan zones and localized fresh sulphide dissemination (chalcopyrite and pyrite).

The project is open for exploration.
