Colibri Resource Corporation reported that its option partner Tocvan Ventures has released that it has concluded the leaching process of bulk sample material at the Pilar Gold and Silver Project at the Pilar Project in Sonora, Mexico. Tocvan is in year 4 of a 5-year agreement to earn an initial 51% of Colibri's Pilar Gold & Silver Project. Tocvan Ventures Corp.

provided an update and sampling results from a Bulk Sample being completed at its Pilar gold-silver project in Sonora, Mexico. The leaching process has concluded, and the Company's technicians are now washing and prepping the leach pad for final sampling, decommissioning and precious metal recovery. The leaching process was active for 44 days, extracting gold and silver from over 800 tonnes of bulk sample material.

Sampling of the Bulk Sample material was completed in May, results from ALS (Hermosillo) provided an average grade of 1.9 g/t Au and 12.7 g/t Ag. An onsite laboratory was used to sample the pregnant solution during the program with weekly duplicate samples sent to certified labs LTM (Hermosillo) and SGS (Durango). LTM (Hermosillo) will provide an official calculated head grade and recovery of gold and silver based on their final analysis of the data.

The Company is pleased with the progress of data capture throughout the process and encouraged by the early indications of successful gold and silver recovery. As previously announced, an additional 350 tonnes of crushed material and 250 tonnes of raw-bulk sample are available for gravity recovery and later agitated leach testing. Samples collected from the fine fraction of screened material not included in the heap leach pile averaged 2.1 g/t Au and 14.8 g/t Ag.

The fine fraction along with additional bulk sample material will be used in testing gravity recovery methods with later agitated leach, as suggested by the leaching study completed by LTM, showing potential for the high recovery of both gold and silver. A new agitated cyanide bottle roll test by LTM of 20 Mesh material has returned 81% recovery of Gold and 99% recovery of Silver after a 72- hour retention time. Over the retention time, a moderate low sodium cyanide consumption of 0.47 kg/t and moderate CaO consumption of 1.72 kg/t were recorded.

LTM recommends bottle roll studies be completed for three different grind sizes (100 Mesh, 140 Mesh and 200 Mesh) to evaluate the impact to extraction.
