Excellon Drills 154 Metres of 101 G/t AgEq at Evolución Further Demonstrating Regional Potential

 

 

 

 

 

Excellon Resources Inc. (TSX:EXN) (OTC:EXLLF) is pleased to report further exploration results from the Evolución Property in the state of Zacatecas, Mexico. This program is the first drilling in the area since 2010 and follows an extensive, year-long prospecting and mapping program which has identified several priority targets.

 

Highlights

 

  • Broad intersections of continuous silver, lead and zinc mineralization with anomalous gold intersected on the Lechuzas vein, with an open strike of 600 metres and open below 500 metres with high grade zones, including:
  • 101 g/t silver equivalent (“AgEq”) (22 g/t Ag, 0.4% Pb, 1.0% Zn and 0.1 g/t Au) over 154 metres in EX18MAZ-251, including 532 g/t AgEq (188 g/t Ag, 4.4% Pb, 2.9% Zn and 0.1 g/t Au) over 2.4 metres and 238 g/t AgEq (48 g/t Ag, 0.7% Pb, 2.8% Zn and 0.1 g/t Au) over 17.7 metres;
  • 70 g/t AgEq (14 g/t Ag, 0.3% Pb, 0.7% Zn and 0.1 g/t Au) over 219 metres in EX18MAZ-253, including 274 g/t AgEq (70 g/t Ag, 1.3% Pb, 2.2% Zn and 0.4 g/t Au) over 12.6 metres;
  • 663 g/t AgEq (175 g/t Ag, 4.3% Pb, 5.4% Zn and 0.4 g/t Au) over 3.4 metres in EX18MAZ-257; and 
  • 259 g/t AgEq (64 g/t Ag, 1.4% Pb, 2.2% Zn and 0.3 g/t Au) over 24.9 metres in EX18MAZ-258.

 

“We are still in the early days of exploring at Evolución, but the grades, widths and consistency of mineralization that we have intersected along strike and down dip are very encouraging,” stated Ben Pullinger, Senior Vice President Geology. “This drilling has loosely defined a large disseminated mineralized zone and we are working to use this data to vector in on higher grades in future drilling. We continue to view these results as evidence of a large mineralized system especially considering the amount of metal represented in these intersections and the numerous additional veins to be tested regionally.”

This program followed up on promising results encountered in earlier drilling on the Lechuzas structure in EX18MAZ-236 and EX18MAZ-235 (see Lechuzas sections below). The program succeeded in tracing mineralization along strike for 600 metres and to a depth of approximately 500 metres, where it remains open along strike and down dip. Follow up drilling associated with this target will be focused on delineating higher-grade vectors within the system. Mineralization at the Lechuzas target is hosted within the Caracol formation, which is a host to the most significant deposits within the Fresnillo trend. Precious and base metal mineralization occur within and associated with carbonate veining in structures in the host formation. Pyrite, sphalerite and galena are the most commonly observed minerals within the mineralized intervals. Drilling to the north west in EX18MAZ-258 and 259 also encountered mineralization associated with silica and quartz veining. Textures observed within the calcite veins display blading with banding, with similar textures also observed when silica is noted in veins.    

 

Other Targets

 

Drilling at other targets including the Abejas, El Cobre, Pastizal and Negrillas veins was also conducted as part of this program. Holes EX18MAZ-242, EX18MAZ-250 and EX18MAZ-252 drill tested a quartz-calcite vein at Abejas. All holes intersected the target structure with anomalous precious metals values intersected in EX18MAZ-242. At El Cobre, EX18MAZ-241 encountered no significant mineralization. Anomalous mineralization was encountered in EX18MAZ-243 and EX18MAZ-244 which targeted the Pastizal vein. EX18MAZ-243 intersected 65 g/t AgEq (50 g/t Ag, 0.01% Pb, 0.04% Zn and 0.27 g/t Au) over 0.7 meters and EX18MAZ-244 intersected 197 g/t AgEq (131 g/t Ag, 0.1% Zn and 0.8 g/t Au) over 0.7 metres.

 

Three holes were completed at the Negrillas target following up on mineralization intersected in historical drilling. EX18MAZ-247 intersected 43 g/t AgEq (23 g/t Ag, 0.3 %Pb, 0.2% Zn) over 4.2 metres and EX18MAZ-248 returned 506 g/t AgEq (477 g/t Ag, 0.3% Pb, 0.3% Zn, 0.3 g/t Au) over 1.14 metres. EX18MAZ-249 encountered no significant mineralization.

 

Mineralization in the  Evolución region is hosted in epithermal quartz veins typical of the Fresnillo silver belt, most proximally at Hecla Mining Company’s San Sebastián Mine, 42 kilometres to the northwest and along strike from Evolución. Mining was historically undertaken on the Calvario Vein and via multiple shafts along the structures being tested as part of this program.

 

The Evolución property covers 45,000 hectares (450 km2) and 35 kilometres of strike in one of the world’s premier silver districts. The property includes a mineral processing facility, which the Company utilizes to process ore from its Platosa Mine in the state of Durango, Mexico. The mineral processing facility currently has capacity of 800 tonnes per day (“tpd”), with a 650 tpd ball mill in operation and a second, 150 tpd ball mill on standby, with opportunities available for further expansion. Ample capacity remains available to process increased Platosa Mine production and potential new discoveries at either Platosa or Evolución, along with ore from San Sebastián expected to enter bulk sample testing pursuant to a toll milling arrangement later this year.

 

Qualified Person

 

Mr. Ben Pullinger, P. Geo., Senior Vice President Geology, has acted as the Qualified Person, as defined in NI 43-101, with respect to the disclosure of the scientific and technical information relating to exploration results contained in this press release. 

 

About Excellon

 

Excellon’s 100%-owned Platosa Mine has been Mexico’s highest-grade silver mine since production commenced in 2005. The Company is focused on optimizing Platosa’s cost and production profile, discovering further high-grade silver and carbonate replacement deposit (CRD) mineralization on the 21,000 hectare Platosa Project and epithermal silver mineralization on the 100%-owned 45,000 hectare Evolución Property, and capitalizing on current market conditions by acquiring undervalued projects in the Americas.
