Key Highlights

• The ground geophysical survey allowed the interpretation of four systems of vein structures that had already been identified in surface mapping but whose extent was unknown.
• The methods used made it possible to trace one of Aurora's veins, a source of artisanal production in previous years, showing that it has a continuous structure in an extension of up to 700 meters along the strike.
• In addition to showing the continuity of this vein, the survey also indicated the possibility of two more parallel vein structures apparently with similar length. These two parallel vein structures are, at most, 100 meters from the central vein, with the easternmost vein at no more than 50 meters.

Methodology

The geoelectrical survey methodology was chosen because it is known to identify vein structures in the same geological context successfully. The methods are as follows:

• Spontaneous Potential (SP): measures the spontaneous polarization due to electrochemical reactions existing at the host rock vein interface.
• Electrical Resistivity Profiling (ERP): measures the lateral variations of resistivity, trying to delimit the sub-vertical veins by contrast with host rocks.
• Vertical Electrical Sounding (VES): measures the behavior of the resistivity distribution with depth, defining the thickness of the weathered rock and adjusting the frequency used in Electrical Resistivity Tomography.
• Electrical Resistivity Tomography (ERT): measures the lateral and vertical variations of contacts related to the vein system due to its low resistivity characteristics.

The grids used were perpendicular to the vein structures, with variable spacing between 100 and 200 meters and with measuring points every 20 meters.

Results

The geological mapping and sampling on the Aurora target identified occurrences beyond those known from the artisanal production works in Aurora. Due to the coverage by colluvial material and weathered rocks, these occurrences could not be followed in the field, hence the choice of geophysical methods to verify their continuity.

As shown in Figure 1A, the interpretation of spontaneous potential anomalies (zones of low resistivity in blue) allows drawing lines interpreted as veins, previously known only as points with gold occurrences. It was impossible to identify their continuity and extension in the field (Figure 1B).

For the specific area of Aurora's vein, in addition to the vein that was the target of production in previous years showing to be a continuous structure of about 700 meters along the strike, the results of the geophysical survey defined two more potential parallel vein structures, spaced between 50 and 100 meters from this main structure.

Forthcoming drilling will define the potential vein structures further, the results of which the Company expects to be an essential addition of resources to the operations at the Aurora site. For this area, a detailed drill grid is being carried out to test the three parallel vein structures. For the other veins observed, scout drilling is scheduled to be planned to verify thickness and grades.

The geoelectric results of the Quintanillo and Aparecida targets, which are also scheduled to be drilled in 2021, are expected in the coming weeks.

Quality Assurance and Quality Control

All samples were shipped to the SGS Colombia S.A.S.’s (“SGS”) laboratory facility in Medellin, Colombia, where they were prepared and analyzed. They were analyzed using SGS procedure FAA515 to gold (fire-assay on a 50-gram sample with AAS finish) and AAS12C to silver (multi-acid digestion with AAS finish). Over the limit gold was determined by SGS procedure FAG505 (using standard fire-assay on a 50-gram sample with a gravimetric finish).

In line with QAQC best practices, approximately 10% of a 78-sample batch are control samples (three Au-Ag standards: High/Medium/Low grades, two fine blanks, one project blank, and two field duplicates).

SGS is independent of O2Gold. The Company is not aware of any other factors that could materially affect the accuracy or reliability of the data referred to herein.
