The Laberinto Project is located in the “Sierra de la Silla” northwest of the town of Francisco I. Madero in the municipality of Panuco de Coronado. It is approximately 60 kilomteres northeast of the city of Durango City, México. The property consists of mining concession encompassing 91.7 ha.
El Laberinto is situated within the Tepehuano terrane, as are Ana Maria, La Recompensa, and the El Soldado projects, but in close proximity to the contact with the Tahue terrane, W of the Sierra Madre Oriental. The carbonates that host the CRD projects are absent; no Mesozoic rocks survived erosional processes in the region. Instead of the thrust belts of the Sierra Madre Oriental, the region is controlled by a series of North West-South East (NW-SE) to North North West-South South East (NNW-SSE) striking faults that create a horst-and-graben topography.
The main mineralized material at El Laberinto are comprised of iron, lead and zinc sulphides with minor silver sulphosalts. Gold and silver are present with minor lead and copper and to a lesser extent zinc. Values of gold and silver are localized in oxidized portions of the system suggesting that supergene enrichment may be an important component of the deposit. Mineralization is found in quartz veins, veinlet zones and, to a lesser degree, dissemination around veins and veinlets.
In the mid-1990’s, the El Laberinto historical exploration performed by “Compañía Minera Mexicana de Avino S.A. de C.V.” was focused on the objective of evaluating the potential of the main vein.
The historic work consisted of mapping and geological surface sampling, diamond drilling (3 Holes totaling 753.73 metres), mine development of the Jabalí Tunnel, with a strike length of 300 metres over the main structure and 80 metres in a cross-cut.
The historical exploration work as stated above are for historical reference only. The QP has not validated nor verified the data as the information is not currently available. The source of the information is an internal report from the previous operator, Endeavor Silver Corporation.
From September 2012 through to July 2013, work was carried out as part of the agreement between Avino Gold & Silver Mines (Avino) and Endeavour Silver Corp. (EDR) to test the potential of mineralization in the El Laberinto Claim.
This historical work included a mapping and systematic sampling campaign, collecting a total of 208 samples on surface with values of up to 8 grams per tonne (g/t)gold & 421 g/t silver with the anomalous values mostly coming from the Laberinto Structure.
The drilling completed at that time was focused on the South part of the Laberinto Structure which was thought to have had the best potential of mineralization with large volumes and low grades. A total of 5 Holes were completed with 1,367 meters drilled and 2,800 samples were collected in both alteration zones and structures focused particularly in the host rock.
The historic exploration activities as listed above were performed by previous operators. The QP has not validated nor verified the information nor any underlying data however the information is considered reasonable and reliable.
