TORONTO - Terreno Resources Corp. (TSXV: TNO.H) ('Terreno' or the 'Company') is pleased to provide an update on exploration activities at the Las Cucharas Gold and Silver Project in Nayarit, Mexico.

The Company has received results from ongoing fieldwork, with 52 samples collected from the Los Gallos, La Union, Las Palomas, El Zapotillo, El Carrizo, and Arroyo El Jocuixtle Zones.

The Los Gallos Zone is host to a small underground working, which was covered and inaccessible until recently. The working is a drift developed for 32 metres along the Los Gallos vein structure. Samples 40326-40328 were collected on the face and near the back (roof) of the structure underground, while sample 40329 was a grab sample of vein material collected from an informal miner's stockpile.

The Las Palomas Zone is another mineralized fault structure near Los Gallos, and is thought to be a splay of the Los Gallos structure. Samples 40325 and 40330 show elevated gold and silver values across the structure.

The La Union Zone is one of the major historic production areas at Las Cucharas, and sample 40340 was a grab sample from an informal miner's stockpiled vein material.

The El Zapotillo and El Carrizo Zones are located near the northern limit of the Las Cucharas claim block, with El Carrizo located about 600 metres to the southwest of El Zapotillo. Sampling at both areas focused on altered wallrock at the showings rather than vein structures. Gold and silver values were low, with both areas returning anomalous copper, lead, and zinc in the 100's to 1000's of ppm range: sample 40308 returning 0.99% lead in a 1.5 metre chip sample at El Carrizo.

The Arroyo El Jocuixtle Zone is located in the central area of the claim block. Only 6 samples were collected here with similar anomalous lead and zinc as those mentioned above. The strongest anomaly was sample 40322, which returned 44.4 g/t silver from a weakly altered float boulder.

Fieldwork to date in 2021 has focused on defining the extents of the property-wide Las Cucharas precious metal system, which has been traced over 6 kilometres in strike length. New mineralized zones and splays of the vein system have been discovered and defined in intermediate locations between known showings and past producing small-scale mines. Two new base-metal rich zones have been discovered at La Planta and Los Cuervos. Our observations and technical work to date confirm the size and magnitude of this large hydrothermal system.
