Terreno Resources Corp. Discovers Several New Mineralized Zones at the Las Cucharas Gold & Silver Project in Mexico

The Las Cucharas represents a historic gold and silver mining area with well documented small-scale production from 1903 through 1961 of 3,000 kilograms of gold and 30,000 kilograms of silver (Vargas, 1994, COREMI Pub M-12e). It is located in the southern extreme of the mid-Tertiary Sierra Madre Occidental (SMO) volcanic belt, which hosts many of Mexico's gold and silver deposits. The Las Cucharas is considered a low-sulfidation epithermal precious metal system with significant mineralization occurring along a six kilometre northwest-trending structural zone. The project area consisting of 4,447 hectares is located on seventeen (17) concessions.

In 2018, the planned exploration programs were severely hampered by an unusually strong hurricane season which brought three separate force-five hurricanes and many tropical storms to the region. High rainfall and strong winds resulted in landslides, blocked roads, washed out bridges, and high river levels. Repairs to project access roads were carried out by Terreno from January to March 2019 with a D6 cat. A significant exploration benefit from the extreme weather has been the creation of several new outcrop exposures.

The 2019 exploration programs at Las Cucharas continued to provide additional evidence of a widespread hydrothermal precious metal system with greater size potential and continuity than was previously indicated. Company geologists are focused on a regional and property-wide interpretation of the structural controls on gold and silver mineralization with the intention to develop a reliable geological model for generating potential drill targets. A total of ninety (90) samples were collected from new outcrop exposures. Map 1 indicates the locations of the new sampled zones (SEE MAP 1).

1. La Union - El Cardon Zone

The La Union and El Cardon Zones are sub-parallel vein structures which have been traced over 800 metres in strike length. These zones have significant underground development on several levels and were major contributors to gold and silver production at Las Cucharas.

New exposures have been sampled to the northwest, southeast, and west of the main mineralized zones. Extensions of the structures are typically 1.5 metres in width where exposed, and consists of intense quartz veinlets in a strongly silicified fault breccia matrix. Limonite and hematite iron oxides are common, and pyrite is locally visible.

Sample highlights from the Veta La Amapa (Amapa Vein) are shown below. This structure has not been sampled previously and is located over 150 metres to the southwest of the main La Union structure.

2. Jocuixtle Zone (SEE PHOTO 1)

Jocuixtle is part of the northwest-trending La Italia-Jocuixtle-La Taverna-Los Gallos vein system, which has been traced over 1.2 kilometres, and was an important contributor to historic gold and silver production at Las Cucharas. The main underground working is collapsed and not currently accessible.

The main Jocuixtle structure is a combination of clay-rich fault or sheared volcanic rock with abundant quartz veins and veinlets, and ranges from 1.5 to 4.6 metres wide where exposed. The wallrock typically has fine quartz veinlets and strong clay-sericite alteration with fine disseminated pyrite. Fine disseminated galena and malachite staining occur locally, and hematite and limonite iron oxides are common. The first two samples below represent mineralized wallrock, and the following samples represent vein material.

3. La Guaca and El Coco Zones (SEE PHOTO 2)

The La Guaca Zone is located to the northwest and is thought to be the northern continuation of the La Italia-Jocuixtle-La Taverna-Los Gallos vein system, with a cumulative length of 1.2 kilometres.

The main La Guaca structure in this exposure is 1.5 metres wide with a north-west orientation consisting of drusy quartz veins, calcite veinlets, and abundant iron oxides. Lateral and parallel to the main structure are sericite-clay-calcite alteration zones with fine disseminated pyrite and abundant iron oxides, which in turn, changes outward to propylitic epidote-chlorite-calcite alteration, and then to relatively unaltered intermediate volcanic rock. The main structure and lateral alteration zones are greater than 16 metres in true width. A previously unknown adit is now exposed and follows this structure.

The El Coco Zone is a newly discovered vein exposure approximately 800 metres to the east of La Guaca with a collapsed underground working. The vein structure indicates a northwest strike, is 1.5 metres wide, and consists of abundant quartz veinlets in a fault breccia matrix.

4. Corral de Piedra Zone (SEE PHOTO 3)

The alteration and mineralization style at Corral de Piedra appears very similar to that of the El Molino Zone, and is located approximately 1.5 kilometres to the east-northeast of El Molino. Both zones are located near to the southeast extent of the project area.

At El Molino, gold and silver values are associated with predominantly northeast-trending banded quartz and quartz +/- tourmaline veins, veinlets, and breccias with a characteristic black weathering from a manganese-rich mineral assemblage. Surface sampling from previous operators over a 100 x 380 metre area reported values of 1.13 g/t Au and 143 g/t Ag over 3 metres, with individual samples ranging up to 4.84 g/t Au and 95.4 g/t Ag. Precious metal mineralization in this area appears to be widespread due to the intersection of fault and fracture systems with different orientations.

Several new exposures have also been identified in the 1.5 kilometre area between El Molino and Corral de Piedra with similar alteration and mineralization styles.

New exposures at Corral de Piedra have been traced over a 100 metre long area and appear to define an alteration and vein zone that is over 4 metres wide with an east-northeast orientation. Quartz veins and veinlets show variably banded, brecciated, cockscomb or drusy, and locally chalcedonic textures. Gold values are generally low, but widespread silver values indicate the presence of a large continuously mineralized precious metal zone in this area. Terreno will conduct follow up sampling in this 1.5 kilometre area to determine continuity and potential.

Quality Control and Assays

Rock samples were collected using industry standard documentation including sample location, type, width, and description. Samples were delivered to Bureau Veritas/Inspectorate Laboratories in Durango, Mexico for preliminary sample preparation consisting of crushing, pulverizing, and splitting, and then forwarded to Hermosillo, Mexico, and/or Vancouver, Canada for analysis. Analyses are done for gold (30 gram fire assay with an ICP finish); and 35-element ICP analyses. Samples with values over 10 g/t gold and 100 g/t silver are reanalyzed with a gravimetric finish. Bureau Veritas/Inspectorate is an ISO 9001 certified laboratory facility.
