Monclova


Overview

About the Monclova project:

The Monclova project, located 25km southwest of the city of Monclova, is characterized by a large and highly prospective composite stock that has intruded in to the Cretaceous limestone of the Aurora formation. The Monclova intrusive complex is characterized by a series of intrusions of mainly intermediate composition and has numerous mineral prospects within and surrounding the 12km-sq intrusive stock. Historically, miners have extracted Ag-Pb-Zn and Cu-Au-Fe ores primarily hosted in mantos, veins and skarns.

Two types of mineralization have been identified at the at Monclova Project: (1) Fe skarn mineralization with high Fe along with Cu-Au values (2) silica rich polymetallic replacement and vein mineralization with high Ag-Pb-Zn values along with elevated values of As, Sb, and Hg.

Discovery is carrying out the first significant modern exploration program on two main zones of historical workings and mineralization called the Real Viejo area (including the Corrales area) (“RV”), and the Soledad area (“Soledad”). Smaller historical workings exist at the Romulo area (“Romulo”), the Teodulo area (“Teodulo”), and the Ponciano area (“Ponciano”) where surface mapping, sampling and some underground sampling has been completed. For a location map of the Monclova project, please see “References” section below for link.

About the Real Viejo and Corrales targets:

RV is approximately 2km-sq in size and is located along the southern contact of the Monclova intrusive where a series of Ag-Zn-Pb mineralized, silica-rich vein, replacements, skarn-altered embayments and breccias occur and are primarily northeast-southwest oriented. The mineralized and altered limestone has been mapped as 2-10m thick zones scattered along 1,500m of the contact with the impure limestones of the Aurora Formation.

At RV, mineralization occurs primarily as very fine grains of sulphides (sphalerite, galena and argentite) mixed with oxides of zinc (hydrozincite and smithsonite) and lead (cerussite and plumbojarosite). Mineralization is located both at the intrusive-limestone contact and in limestone as breccia veins and mantos. The existence of multiple styles of mineralization expands the mineral potential at this prospect.

About the Soledad target:

Soledad is located in the northeastern part of the Monclova intrusive complex. Small to large pits were developed for exploring and exploiting prograde massive iron-rich copper gold garnet skarn with bodies of magnetite-rich mineralization formed at the northwest-trending contact of the intrusive and limestone. The iron-rich copper gold skarn is mapped along 500m strike of the intrusive-limestone contact. Underground workings along the contact have not been accessed at this time but indicate extensive interest by miners in the past.

About the Teodulo target:

Teodulo is located in the central part of the composite intrusive and project area. Open cuts and underground access were developed along an 850 meter-long northeast trending fault dipping steeply to the southeast, within the intrusive. The main zone of interest consists of epithermal quartz veins less than 20 cm thick containing silver, lead and copper mineralization within the 1-2-meter-wide Teodulo fault. About 500 meters to the northeast along the projected trend of the Teodulo fault, a cross cut was driven to access mineralization near the creek level but entry has not been possible due to flooding of the workings.

About the Romulo target:

Romulo is located in the east central part of the project. Open cuts were developed along east contact of the composite intrusive and along the contacts of an east-west trending roof pendant of limestone. Most of the workings present exist along the east-west trending contacts of the limestone roof pendant where relatively small iron-rich copper gold skarn replacement zones formed. Underground workings in this area were also developed along a northerly trending fault that cuts the limestone contact. Massive andradite garnet endoskarn is abundant near the east-west contact and along the north-trending east contact of the intrusive and limestone. The skarn mineralization tends to be iron dominant with copper and gold mineralization, although still contains low levels of silver and zinc.
