5. FULL DISCLOSURE OF MATERIAL CHANGE

Full Description of Material Change

Vancouver, British Columbia, August 12, 2021 Leocor Gold Inc. (the " Company " or " Leocor ") (CSE: LECR; OTCQB: LECRF; Frankfurt: LGO) is pleased to announce plans to begin a comprehensive phase one exploration program at its consolidated Baie Verte project portfolio, located in north central Newfoundland, Canada. The Baie Verte project combines the Dorset, Dorset Extension, Five Mile Brook and Copper Creek projects, consisting of fourteen mineral licenses, totalling 80 claims, and covering 1995 hectares (19.95 square km).

Current and historical surface work shows a semi-continuous N-NE strike length of alteration and mineralization between the Five mile Brook South prospect to the Tidewater Prospect. Leocor will be working with GroundTruth exploration on the program which will unify the projects with a common soil database and holistically define what we expect to be a significant mineralized footprint. The GroundTruth method breaks down the exploration process into phases, typically defined as follows:

Phase 1)

• Soils 100 m line separation and 25 m sampling separation

• • Air magnetic survey

• Lidar Survey

• VLF Survey

• 2 -

Phase 2)

• GT Probe Drilling (around areas of interest constituting potential targets)

• Induced Polarization across potential drill targets

Phase 3)

• GT Rab Drilling (typically 60m holes in fences across shallow targets)

Phase 4)

• Diamond or Reverse Circulation drilling (once structure and orientation of target are well defined)

The Baie Verte District is generally perceived to be at a phase 1 stage but because of the more advanced status of certain parts of the project we have budgeted phases 2 and 3 with GT Probe, GT Rab holes, the locations of which are still to be planned.

The planned program is budgeted for 710,000 CA$ and consists of:

Phase 1 171 Line Km of ground magnetic 4943 soil samples 20 Km2 Airborne Lidar survey

Phase 2 5,000 m of Induced Polarization 585 GT Probe samples

Phase 3 15 short, 60 m Rab holes

The distribution of planned work is illustrated in image 1. Image 1A shows ground magnetic lines, soil lines and IP lines over topography and relative to a selection of some of the more important mineral occurrences on the property. Image 1B shows the same data over the district geology. The Baie Verte peninsula is a prolific gold and base metal district and much of the gold in Newfoundland appears to have been deposited in a fairly tight window of time between 437 and 375 Ma. Many of the prospects are associated with extensive alteration/shear zones developed within a thrust-faulted sequence of quartz-Fe-carbonate-fuchsite-altered gabbros, ultramafics and mafic volcanics, of the Advocate (ophiolite) Complex, and intermediate to silicic volcaniclastics & tuffs and microgabbroic dykes/sills, of the Flatwater Pond (cover sequence) Group. The soil and magnetic lines are designed to be perpendicular to the north east strike of the lithologic, structural and alteration regime which controls the mineralization.

Recent Work

Over the past six months Company geologists have identified a significant zone of gold mineralization at the new Braz-NE trench site as well as an extensive gold-in-soil anomaly in the southwestern claims, from which a recent rock sample value of 1.23 grams-per-tonne (“g/t”) gold (“Au”) was obtained.

The most significant gold results, from the Braz-NE trench, illustrated in Image 2, were obtained from a 16.8 m wide section of a 57 m wide iron-carbonate alteration zone, where a total of 12 channel samples were collected. Eight of these, from 20304 to 20311, returned a continuous section of highly anomalous gold results having a combined (average) grade of 1.69 g/t Au over 8m; the latter section includes two subzones yielding 1.47 g/t Au over 4m and 2.49 g/t over 3m. Bounding this zone, to the northwest, is a 3.6m gap (of non-exposure) separating it from a 2.5m wide quartz vein rich zone where three channel samples 20301, 2 and 3 returned an average grade of 3.31 g/t Au over 2.5m. To the southeast of the 8m channel-sampled section, a 0.7 m gap of non-exposure, separates the latter from a 1.6m wide bedrock exposure 20311 returning 1.34 g/t Au over 1.6m.

About Leocor’s Baie Verte Project

The Baie Verte Peninsula represents one of the more productive and historical gold and base metal mining districts in Canada. The former Terra Nova base metal mine – one of several copper mines of the region, which operated during the late 1880’s to early 1900’s – lies 200 meters west of Leocor’s Copper Creek claims. Former gold mining operations in the area include the Goldenville mine (of

1903-1906), located 8 km NE of the property, and the more recent Nugget Pond mine (1997-2000) of the eastern Baie Verte Peninsula area. Currently producing mines in the area include the Rambler base metal-gold mine (1961-present), located 14 km ESE of Baie Verte, and the Pine Cove and Stogertite mines (collectively, 2011-present) located 1.6 km and 5.4 km NE of the current property.

The Baie Verte project combines the Dorset, Dorset Extension, Five Mile Brook and Copper Creek projects consisting of fourteen mineral licenses, totalling 80 claims, and covering 1995 hectares (19.95 square km).

The Dorset Gold Project is a 275-ha gold exploration project, located south of the Pine Cove Gold Mine, and features multiple zones of high-grade gold mineralization. The Main Dorset Zone includes three historic showings, referred to as Dorset 1, 2 and 3 Showings. Grab samples from Dorset 1 returned 407.9, 349.2, 147.1, 143.9, 138.2, 108.0, 106.7, 72.4 and 30.0 g/t Au. Grab samples from Dorset 2 returned 167.0, 96.12, 84.3, 49.7, 23.8,4.33 and 1.33 g/t Au (MacDougall and Walker, 1988) and a “combined assay of 56.0 g/t Au over 2.5m” (MacDougall 1989). Historic drilling includes DDH 87-1, which intersected 9.5 g/t Au over 1.3m (MacDougall and Walker, 1988).

Historic select sampling at the Braz Zone returned values of 314 g/t Au, 40 g/t Au, 31.4 g/t Au, 21.2 g/t Au, 19.2 g/t Au and 14.8 g/t Au. Historic channel sampling across the vein returned 9.5 g/t Au over 0.4m, 5.7 g/t Au over 0.5m and 1.2 g/t Au over 0.65m. Weighted averages of historic rock sampling encompassing vein and mineralized wall rock returned values of 5.8 g/t Au over 1.9m, 3.1 g/t Au over 2m and 2.5 g/t Au over 1.5m (MacDougall, 1990).

Other zones include The Albatross, where historic rock sampling of mineralized zones returned values up to 30.3 g/t Au. Assay results from three 1987 diamond drill holes include 1.0 g/t Au over 7.3m, 1.81 g/t over 4.3m and 1.02 g/t over 2.2m and the Gunshot Zone, where veins containing visible gold and pyrite returned grab samples that assayed up to 162 g/t Au and channel samples that assayed up to 18 g/t Au over 0.4m (MacDougall, 1989)

In the Phoenix Zone, “assays from initial grab samples returned 5.8 and 5.5 g/t within the gabbro. Quartz veins have returned 1.4, 0.6 and 0.5 g/t Au. Similar mineralization located 500m north east returned 3.3 g/t.” (MacDougall, 1987). Diamond drilling hole intersected of 1.07 g/t Au over 5.45m (MacDougall, 1989).

Copper Creek (1,025-ha) hosts a number of gold prospects and copper occurrences associated with extensive alteration/shear zones developed within a thrust-faulted sequence of quartz-Fe-carbonatefuchsite-altered gabbros, ultramafics and mafic volcanics, of the Advocate (ophiolite) Complex, and intermediate to silicic volcaniclastics & tuffs and microgabbroic dykes/sills, of the Flatwater Pond (cover sequence) Group. Historical results at Copper Creek – Biarritz zone include “values ranging from 1.3 to 16 g/t Au from grab samples and a combined assay of 3.9 g/t Au over 4.0m from detailed chip sampling.” Additionally, “300m SW along strike exposed a 5-10m shear zone with similar alteration returned which returned sporadic values up to 9,2 g/t Au from grab samples” Noranda drilled several diamond holes in the area including A-88-7 which returned 0.66 g/t Au over 1.5 m and A-88-9 which returned 3.11 g/t Au over 0.5 m. (MacDougall, 1989).
