Imiter bis (Ag, Au, Cu, Pb, Zn)

About Imiter bis

Imiter bis, formerly known as 233263 Permit, is an exploration property located on Morocco’s sub-Atlas range, about 150 kilometers from Ouarzazate and just five kilometers south of the world-class Imiter Mine. A 10,000m core drill program is scheduled for 2022 to follow up on 2021 scout drilling results.

Highlights

Ownership: 100%
One exploration permit covering 16 km²
Initial fieldwork: identification of a potential 4-km at-surface polymetallic structure (see left figure)
2021 scout drilling on 4 zones confirmed presence of gold and silver in several discovery holes

Vein system of 4km structure located close to major contact between granodiorite and main mafic dyke
Program confirmed continuity at depth with increasing widths in Middle Zone

2022: 10,000m drill program planned to follow up 2021 drill results

Focus on north extension of Middle Zone & to find the “boiling zone” with richer mineralisation

Q2-Q3- 2022 Airborne survey and heliborne VTEM geophysical survey planned

Location

The property is located in the Proterozoic Saghro “boutonnière” of Morocco’s Sub-Atlas range, about 150 kilometers from Ouarzazate and five kilometers south of the world-class Imiter Mine. Roads from Imiter village lead to the northern and southern ends of the property.

Geology

Imiter bis is underlain by a complex bi-modal volcanic sequence of the Ourzazate Supergroup overlying the Precambrian pelitic sequence of the Anti-Atlas Supergroup that hosts the Imiter silver deposit. The host bi-modal volcanic sequence consists of flow-banded rhyolite, felsic volcanic conglomerates, porphyritic dacite and andesite, and basalt. The host sequence is intruded by multiple syn-volcanic granitic and granodioritic intrusions and mafic dykes.

The property is cut by two major structures filled by low-sulphidation epithermal vein systems, oriented in a N-S and NE-SW orientation, associated with the regional fault system. Additionally, multiple syn-to-late-volcanic faults associated with caldera collapse cut the sequence, most of which are strongly mineralized.

Mineralization

The Imiter bis property is strongly endowed with Au-Ag-Cu-Pb and Zn mineralization at surface associated with several orientations of quartz veins, hydrothermal breccias and syn-to-late volcanic faults. The bulk of the precious and base-metal mineralization observed is associated with two major epithermal vein systems that range from 1.5 meters to 2.0 meters in thickness and locally reaches 10m wide, spanning the length of the permit in a N-S and NE-SW orientation. Epithermal vein textures observed at surface mainly consist of massive, bladed, brecciated, comb textures and chalcedonic quartz, which suggest that the mineralization observed at surface is above the boiling point and that the associated precious metal-rich zone is at depth. The main sulphide minerals observed in these veins consist of minor blebs of chalcopyrite, malachite, and galena along with massive hematite filling box-work and fractures.

Additionally, copper-rich zones have been identified in two different settings: first, in the eastern portion of the property associated with several parallel NW-trending late-volcanic faults, cutting a granodioritic intrusion. These faults are filled with malachite, azurite (see figure left), and minor fresh chalcopyrite. Second, a disseminated mineralization of malachite after chalcopyrite is regularly distributed in a mafic volcanic sequence in the central part of the property.

Exploration

The 10,000m diamond drill program scheduled in 2022 will test new prospective areas defined by the airborne survey and follow up on the Q4-2021 drill results (see left figure). Starting in Q2-2022, the drill program will focus on the northern extension of the Middle Zone in addition to untested targets (Northwest Zone, Dilatation Zone and Daoud Zone).

Geophysics

In addition to the drilling program, a high-resolution magnetic ground survey consisting of 109 km of grid lines at 50m x 5m spacing has been conducted on the central portion of the permit covering the five priority targets. An airborne survey commenced in Q1-2022.

History

2011

In 2011, trenches, small shafts and adits were discovered in several areas of the property. The excavations mainly investigated hematized-quartz-carbonate veins containing malachite, azurite, galena and sphalerite. There is no record of past exploration.

2012

In 2012, an IP/resistivity survey consisting of 62 gridlines was carried out on the central part of the permit, revealing 2 main geophysical domains.

2021

A fieldwork program involving mapping, grab sampling, channel sampling and trenching was carried out on the property between June and October 2021. A detailed ground MAG survey was completed.
