Figure 1. Diamante 1 and 2 Concessions, north and south, respectively, showing current targets for 2024 program. Regional location shown in southeastern Sonora State, Mexico. Eight principal drill target areas with 17 permitted pads and requisite access routes (DIA 1 - La Prieta, El Pillado-El Caso-La Cruz, El Chon-El Chon Ouest, DIA 2 - Mezquite Raizudo, Calton, Anomalia Sur) are shown on shaded topography (GMCA report, January 2024).

Diamante Exploration

The Diamante property hosts numerous historical artisanal and small-scale mining sites and combined with mineralization on the Jackie property exhibit the geological characteristics of epithermal low to intermediate sulfidation Ag-Au (Pb-Zn), high sulfidation Au-Cu, and potential transition zones within and peripheral to porphyry style Au-Cu mineralization.

Sporadic surface exploration since 2011 has resulted in several surface showings comprised of epithermal precious and base metal mineralization (Au-Ag+/-Cu, Pb, Zn). Colibri and Silver Spruce commenced geochemical and geological exploration activities on Diamante during 2021. The 2022 exploration plans included a 2,000 metre reverse circulation drill program on Diamante 1 and 2 to evaluate four to seven of the principal targets exhibiting high grades of polymetallic Au-Ag-Pb-Zn-Cu mineralization with coincident alteration, shearing and veining.Mineralization was 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.

Colibri (operator) and Silver Spruce completed the first-ever drill program on Diamante at the El Pillado and La Prieta targets located on Diamante 1. Results from the 2022 drilling include 2.48 grams per tonne ("g/t") Au and 56.7 g/t Ag over an intersection length of 9.0 metres ("m") from La Prieta and 0.26 g/t Au and 184.5 g/t Ag over an intersection length of 6.0 m from El Pillado. Drilling at both targets intersected highly anomalous base metals in highlighted drill assay intervals. Through the fall of 2023, Colibri and Silver Spruce completed a program of geological mapping, rock sampling and stream sediment sampling on Diamante resulting in the discovery of two new surface showings (see Colibri press release January 9, 2024). The prioritization of targets and drill plan for Diamante was based on this work combined with comprehensive compilation and interpretation of historical exploration information.
