Curipamba Project

In September 2017, Adventus entered into an agreement with Salazar Resources Limited ("Salazar") (TSX-V: SRL) whereby Adventus may earn a 75% interest in Salazar's Curipamba Project located in Ecuador by funding exploration and development expenditures of US$25 million over the next five years.

The companies are exploring for volcanic massive sulphide ("VMS") as well as hydrothermal gold-silver style deposits within the Curipamba Project's vast and under-explored 21,500 hectare concession area, while also working on the completion of a feasibility study of the El Domo deposit.

El Domo Deposit

The most advanced known deposit within the 21,500 ha Curipamba Project is the El Domo deposit - a VMS generally tabular lens with approximate dimensions of 800 metres long by 350-500 metres wide, beginning 30 metres from surface. The latest NI 43-101 mineral resource estimate can be found on Adventus' PEA news release, dated May 2, 2019 and the table on this page.

To date, over 60,000 metres of drilling has been completed on El Domo. The 2018 infill drilling program as recommended by the Roscoe Postle report yielded some of the highest grade drill results globally, which include:

  • 24.02 m of 5.41% copper, 6.40 g/t gold, 2.68% zinc, 58.6 g/t silver, 0.15% lead (~11.5% CuEq1) – CURI 336
  • 21.10 m of 5.49% copper, 3.94 g/t gold, 2.77% zinc, 42.3 g/t silver, 0.19% lead (~9.8% CuEq1), including: 8.70 m of 11.31% copper, 7.81 g/t gold, 6.57% zinc, 90.9 g/t silver, 0.44% lead (~20.3% CuEq1) – CURI 300
  • 8.16 m of 2.17% copper, 19.67 g/t gold, 23.17% zinc, 229.0 g/t silver, 4.01% lead (~28.4% CuEq1), including: 3.71 m of 3.00% copper, 36.55 g/t gold, 32.17% zinc, 411.3 g/t silver, 6.80% lead (~47.0% CuEq1) – CURI 285
  • 32.43 m of 4.40% copper, 1.29 g/t gold, 1.84% zinc, 13.3 g/t silver, 0.09% lead (~6.2% CuEq1), including: 19.41 m of 7.00% copper, 1.61 g/t gold, 3.00% zinc, 18.4 g/t silver, 0.14% lead (~9.5% CuEq1) – CURI 266

Adventus and Salazar believe significant exploration potential exists to expand the El Domo deposit as well as to find additional deposits within the greenfield Curipamba Project, which was only discovered in 2008. 

A detailed airborne geophysical program on the full 21,500 hectare land package is expected to be completed in Q2 2019 and will be the first time the project area has been the subject of a modern geophysical survey highlighting the true under-explored nature of this prospective belt.


Greenfield Exploration at Curipamba

The 2019 exploration program aims to target new discoveries by utilizing and combining the results from first regional airborne geophysics survey with known surface sampling results and geochemical targets.

Key targets at Curipamba in addition to El Domo:
  • Sesmo: 15 m @ 39 g/t Au, 741 g/t Ag in channel sample
  • El Gallo: 597 m drilling in 5 holes; highlights: 6.95 m @ 4.51 g/t Au, 157 g/t Ag; 8.25 m @ 5.80 g/t Au, 66 g/t Ag
  • Sesmo Sur: 3,746 m drilling in 18 holes; highlights: 12 m @ 2.25 g/t Au, 31 g/t Ag; 15 m @ 2.54 g/t Au, 50 g/t Ag
  • La Vaquera: strong alteration in 1.2 x 2.5 km area
  • Agua Santa: semi massive + jasper float, with Au, Cu, Zn
  • Barranco Colorado: stockwork of pyrite + sphalerite, with traces of chalcopyrite in dacite rhyolite, and jasper float
  • Coral: intense alteration chlorite-argilic (2 km x 1 km)


Historic channel sample results (late-2000s) rank highly among global benchmarks today:
