Introduction Sonora State, Mexico QUICK FACTS ➢ Trades: TSX.V: CBI | FSE: 2CO ➢ Property Portfolio Focused on Sonora, Mexico ➢ Led by an Experienced Management Team and Board who have Found, Developed, and Managed Producing Mines CORPORATE STRUCTURE ➢ 59.1 million shares outstanding ➢ 86.6 million shares fully diluted Hermosillo Office ➢ Based in Moncton, New Brunswick, Canada FIVE EXPLORATION PROJECTS IN SONORA, MEXICO ➢ Pilar ➢ Evelyn ➢ El Mezquite ➢ Pitaya – JV with Agnico Eagle (being sold) ➢ Jackie TSX Venture: CBI 3

Why Mexico? Why Sonora? 1. Mexico - 8 th largest producer of gold globally at 125 million metric tons – (1 st in silver production) 2. Mexico - Politically stable country – Mining friendly (approximately 4% of GDP) 3. Well Endowed Geologically – Sonora State represents the largest share of annual gold production in the country 4. Sonora has an affordable & experienced labour force and materials are easily sourced 5. All Colibri projects are geographically near producing or past producing mines 6. 4 of 5 of Colibri’s exploration projects have historic artisanal mining on property – increased probability of finding additional deposits using modern science
