Las Cucharas Gold & Silver Project in Mexico Updates Historical Background & Exploration Results
TORONTO, February 11, 2020 - Terreno Resources Corp. (TSXV:TNO.H) ("Terreno" or the "Company") George A. Brown, President & CEO, is pleased to provide information an update on the historical background and geological environment of the Las Cucharas Gold and Silver Project ("Las Cucharas") in Nayarit, Mexico. WHY MEXICO?
Mexico has a rich mining history and is blessed with a wide variety of geological environments and mineral deposit types. Spanish colonial-era silver and gold production from the Veta Madre mine in Guanajuato ranked second only to Bolivia's Cerro Rico at that time.
Mexico consistently ranks in the world's top 10 producing countries for gold, silver, and copper. Other important mineral products include lead, zinc, uranium, coal, iron, and graphite. The total value of minerals produced in Mexico in 2018 was $US 12.57B including precious, non-precious, and industrial minerals. Foreign direct investment in mining and exploration ranked fourth worldwide in 2018 at $US 1.4B. 6,100 tonnes of silver was produced in Mexico in 2018 alone (ref INEGI - Instituto Nacional de Estadistica y Geografia - National Institute of Statistics and Geography; and CAMIMEX - Camara Minera de Mexico - Mexican Chamber of Mines).
WHY LAS CUCHARAS?
Las Cucharas is 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 most significant gold and silver deposits (SEE MAP 1). The state of Nayarit in Mexico is host to several important producing mines, past producing mines, and well known mineralized districts (SEE MAP 2).
The Las Cucharas project area is 4,447 hectares covered by seventeen (17) concessions (SEE MAP 3). Significant underground workings have been developed at several different zones, including La Union, El Cardon, Los Gallos, Jocuixtle, La Italia, and La Raizura. These workings are often hundreds of metres in length and developed on several levels. Most of the remaining known showings have exploratory adits.
The Las Cucharas Project is classified as a volcanic-hosted low-sulfidation epithermal precious metal system, with significant mineralization occurring along a six kilometre northwest-trending structural zone. Gold and silver are hosted in vein and shear structures, stockwork zones, and breccias. Classic low sulfidation textures are common, including banded quartz veins and breccias, as well as drusy, bladed, and chalcedonic quartz. Historical exploration work was carried out by Maverix Metals Inc. (formerly MacMillan Minerals Inc. and the predecessor company MacMillan Gold Corp.) between 2003 through 2012. This work succeeded in identifying fourteen separate mineralized showings.
Maverix carried out several phases of surface and underground geological mapping, rock and soil sampling, trenching, local geophysics, and drilled approximately 2,190 metres in 15 exploration diamond drill holes (SEE MAP 4).
Some work highlights include:
-
- Surface grab samples ranging up to 18 g/t Au and 807 g/t Ag in the Nuevo Cucharas/La Taverna Zone.
-
- Underground channel samples ranging up to a weighted average of 3 g/t Au and 292 g/t Ag over 2 metre width and 71 metre strike length in the La Raizura underground working.
-
- Exploration drill holes tested several of the known mineralized zones, and all but 3 of the holes returned significant gold and silver values. Several highlights reported by Maverix include the following:
| HOLE | ZONE | FROM (m) | TO (m) | DRILL WIDTH (m) | EST. TRUE W (m) | Au (g/t) | Ag (g/t) |
| BL RZ-001 | LA RAIZURA | 96.5 | 110.0 | 13.5 | 13.0 | 1.94 | 14.6 |
| BL RZ-003 | LA RAIZURA | 77.6 | 84.8 | 7.2 | 2.2 | 2.54 | 103.9 |
| B AZ-001 | LA AZURITA | 12.2 | 13.2 | 1.0 | - | 5.7 | 343.1 |
| LU-01 | LA UNION | 64.3 | 67.5 | 3.2 | 3.1 | 3.09 | 36.5 |
| EC-01 | EL CARDON | 157.5 | 165 | 7.5 | 5.7 | 4.42 | 8.4 |
These exploration results evaluated along with the historic production clearly demonstrates significant precious metal potential at Las Cucharas, and Terreno's management is very pleased to be working on a project of this quality.
