Colibri Resource Corporation provided high-grade results from additional historical rock sampling at several known targets with artisanal workings. Recent literature research identified reports with maps, field sampling sections and assays for seventy-seven (77) previously unreleased samples with precious and base metal values reporting up to 25.69 g/t Au, 1,360 g/t Ag, 18.2% Pb, 33.5% Zn and 1.47% Cu. The surface and U/G channel samples (to 2.5 metres) were collected from Diamante 1, the northern concession, at the La Prieta, Aguaje, El Chon, El Chon Oeste, El Chon Sur, Hacia del Oeste, La Olla, Lupita, Pillado, Pillado Sur and Pillado Grande targets.

The highest-grade individual sample was collected from a 15cm vein in the La Prieta workings (25.69 g/t Au, 1,265 g/t Ag, 18.2% Pb, 23.0% Zn and 1.47% Cu). The Diamante gold-silver (Au-Ag) project is a drill-ready precious metal property located 5 km northwest of the town of Tepoca, and 165 km southeast of the capital city of Hermosillo, eastern Sonora, Mexico. Diamante offers strong precious metal tenor with a polymetallic endowment and contains multiple quality targets, limited artisanal mining and small-scale production, of particular significance for exploration moving forward, no records of drilling on either property.

Historical Rock Sampling: The recently acquired reports and maps contained polymetallic assays of rock samples from La Prieta, Aguaje, El Chon, El Chon Oeste, El Chon Sur, Hacia del Oeste, La Olla, Lupita, Pillado, Pillado Sur and Pillado Grande targets. Diamante includes twelve known occurrences at La Prieta, El Aguaje, El Chon, El Pillado, La Olla, La Cruz and El Caso, Mezquite Raizudo, El Puerto, El Cumbro, Calton and the Southern Anomaly (Anomalía Sur). Sampling highlights from these areas of interest, some with artisanal mining, have reported significant precious and base metals in samples collected from historical mine dumps, small-scale processing slag and assays from vein and stockwork-style mineralization.

Based on the distribution of the overall sampling (n=354), several newly renamed targets are designated, and the Diamante concessions overall comprises eighteen mineralized areas with seven under consideration for the Phase 1 drilling. These include La Prieta, El Cumbro, Mezquite Raizudo, El Chon, La Olla, Calton and Pillado. Disseminated and stockwork mineralization at Anomalía Sur and El Puerto offer bulk low-grade targets.

Project Geology: The Property is located within the west-central portion of the Sierra Madre Occidental Volcanic Complex within the prominent northwest-trending "Sonora Gold Belt" of northern Mexico and parallel to the well-known, precious metals-rich Mojave-Sonora Megashear. Exploration has identified geological features of epithermal low to intermediate sulphidation Ag-Au (Pb- Zn), high sulphidation Au-Cu, and potential transition to porphyry style Au-Cu. Precious and base metal polymetallic mineralization occurs as disseminated, stockwork and vein styles accompanied phyllic, argillic, advanced argillic and propylitic zones, with near-surface overprinting by weathering with iron oxide and oxyhydroxide staining, jarosite and relict vuggy silica.

New TLALI algorithm maps for the LANDSAT 8 OLI and LANDSAT/ASTER data confirmed the spectral response for silicification and argillic alteration, including generic clay, alunite, pyrophyllite, kaolinite and silica coincident with known artisanal vein workings and disseminated gold targets. Mineralization is reported visually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous galena, argentite, hematite and probable metal oxides, carbonates and sulphates, including copper carbonate (malachite), copper sulphates and plumbojarosite. Structural lineaments with ENE, NE and NW orientations identified in the historical exploration correspond to known vein systems. Branching and oblique vein sets to the N-S direction were noted from the ENE veins.
