Avrupa’s Sesmarias discovery on the Alvalade Project
 

Avrupa acquired the Alvalade Project in 2010 and initially optioned it out in 2012, but has been the operator of the project since acquisition. During that first earn-in period (2012-15), an initial hole, SES002, was drilled into the Sesmarias target and intersected 10.85 meters of 1.81% copper, 2.57% lead and 4.38% zinc. Drilling encountered numerous faults, but subsequent holes hit mineralization, on and off, over a 1.8 kilometer strike length, including SES010 which intersected 58 meters of 0.32% copper, 0.61% lead, 1.95% zinc, 0.45 g/t gold, 25 g/t silver.

A summary of some of the previously announced results from Alvalade is presented below:

  • SES002 – 10.85 meters @ 1.81% Cu; 75.27 ppm Ag; 2.57% Pb; 4.38% Zn; 0.13% Sn
  • SES006 – 1.5 meters @ 1.66% Cu; 54 ppm Ag; 2.30% Pb; 3.66% Zn; 0.091% Sn  -- mineralization cut off by faulting
  • SES008 – 5.0 meters @ 0.64% Cu; 36.8 ppm Ag; 0.94% Pb; 1.54% Zn –   mineralization cut off by faulting
  • SES009 – 2.3 meters of massive pyrite (not analyzed)
  • SES010 – 57.85 meters @ 0.45 g/t Au; 25.1 g/t Ag; 0.32% Cu; 0.61% Pb; 1.95% Zn

The Project was optioned out a second time in Q3 2015.  During this earn-in period (2015-17), Avrupa drilled four additional holes into the Sesmarias target area that confirmed and extended one massive sulphide lens in the area to a length of 300+ meters with a 20-40 meter thickness. The lens is open to the northwest and down dip to the northeast.  The assays from those four holes are reported below.

Table 1.  2015-16 drill intercepts from the SES010 lens.

In 2015, Avrupa conducted downhole geophysics, utilizing the “mise-a-la-masse” (MALM) method, and combined with historic ground magnetics data, suggested that the sulfide lens may continue another 300 meters or more to the northwest from SES022. 

To date, 54 holes have been drilled around the license by Avrupa for a total of 21,121 meters.  More than 10 of the holes intercepted massive sulfides with various grades of copper, lead and zinc. 

There are at least four other separate targets in the immediate Sesmarias area, a significant target in the Pombal area located about 15 km southeast of Sesmarias, and several targets at the Monte da Bela Vista stockwork discovery located about 10 km north of Sesmarias, all on the Neves Corvo mineral trend.  Numerous general targets exist on the Aljustrel mineral trend, on the São Domingos mineral trend, and in several other areas along the Neves Corvo mineral trend.  All three mineral trends cut the Alvalade license, giving a total of 85 km of prospective Pyrite Belt potential on the license.

The Project is again 100%-owned by Avrupa, and available for Joint Venture. The Company is actively engaging potential partners for review of the Project.
