Strong demand and declining reserves have helped move gold, silver, and copper prices to their multi-year highs in 2021 and one junior miner has taken advantage of a robust resource of these metals in Mexcio.
Terreno Resources Corp. (TSX-V: TNO.H, Forum) is a Toronto-based exploration-stage Company, engaged in the acquisition, exploration, and development of mineral properties - primarily gold and silver, with more potentially awaiting deeper under the surface.
This past spring, Terreno provided investors an update on exploration activities at the Las Cucharas Gold and Silver Project in Nayarit, Mexico. Results from several newly discovered showings saw 54 samples collected from the Arroyo El Jocuixtle, Los Cuervos, El Zapotillo, Arroyo del Tiro, and Potrero de Don Teodulo Zones (see map below). Management believes that the discovery of
more than 1% copper adds a new dimension to this project. Samples were collected as continuous chip samples along marked lines unless otherwise noted. A summary of significant results was provided by the Company in a table below:

Abundant iron oxides have been identified on a NW-trending brecciated fracture and fault structure where samples from Arroyo El Jocuixtle were collected. Several small-scale exploration adits were sampled from the El Zapotillo Zone is located near the northern limits of the Las Cucharas claim block, returning up to 1.97 g/t Au over a 65-centimeter sample width, and 119.0 g/t Ag over a 1.1 metre sample width (see image at top.)
Silver values near the La Planta Zone, the Arroyo del Tiro, and Potrero de Don Teodulo areas ranged up to 26.3 and 22.5 g/t Ag, both over 1.5 metre sample widths. The Company noted that while these values are lower, they do indicate that the mineralized hydrothermal system is persisting in these areas.

TNO followed this news up with results from ongoing fieldwork over the summer at Las Cucharas, with
52 samples collected from the Los Gallos, La Union, Las Palomas, El Zapotillo, El Carrizo, and Arroyo El Jocuixtle Zones (see map above).

Inaccessible until recently, the Los Gallos Zone is host to a small underground working. The working is a drift developed for 32 metres along the Los Gallos vein structure. Near Los Gallos, the Las Palomas Zone is another mineralized fault structure, thought to be a splay of the Los Gallos structure. The La Union Zone is one of the major historic production areas at Las Cucharas.
To date this year, field work 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. Within intermediate locations between known showings and past producing small-scale mines, new mineralized zones and splays of the vein system have been discovered and defined. Two new base-metal rich zones have been discovered at La Planta and Los Cuervos. The team’s observations and technical work to date have confirmed the size and magnitude of this large hydrothermal system.
Terreno’s geologists believe that the project hosts two distinct styles of mineralization with a continuous transition between them. These are:
- Discrete, gold and silver rich low-sulfidation epithermal style quartz veins
- Base-metal rich polymetallic vein and disseminated lead-zinc-copper-silver zones
Looking ahead, the Company recently announced that it is preparing a drilling program for
the fall 2021 at Las Cucharas, following this successful exploration season. The team noted that very high gold and silver assay values were returned from samples of selected vein material.

Many analysts and economists believe that gold prices will continue to climb higher as the global economy works to rebound from the COVID-19 pandemic. Investors who want in on this action sooner than later and are looking for a stable play in a safe jurisdiction where results have already been impressive would be wise to deepen their due diligence into what Terreno Resources Corp. has to offer.
