Diablillos - Silver Deposit or Gold Deposit with a Silver Cap? AbraPlata defines three gold zones at Oculto deposit
Diablillos - Silver Deposit or Gold Deposit with a Silver Cap?
AbraPlata defines three gold zones at Oculto deposit
BUENOS AIRES – April 30, 2018 , - AbraPlata Resource Corp. (TSX.V:ABRA; OTC : ABBRF; Frankfurt: 1AH )
("AbraPlata" or the "Company") is pleased to announce that geological mapping by the Company’s consulting
geologist, who is an epithermal specialist, has identified new hydrothermal breccia zones and extended those
already known at the Company's 100% owned Diablillos silver -gold project in Sal ta Province, Argentina . The
presence of these hydrothermal breccia zones opens up the potential for additional high grade gold
mineralization in the basement lithologies both below, as well as lateral to, the currently defined Oculto silver-
gold deposit in the overlying volcanics.
“These breccias represents a new satellite prospect that has the potential to dramatically expand the gold
resource in the Oculto deposit and could improve the already robust economics disclosed in our recent
Diablillos PEA report,” commented Willem Fuchter, President and CEO of AbraPlata. “It also begs the question
of whether Diablillos will ultimately prove to be a primary silver deposit or a gold deposit with a silver cap. In
order to answer this question, we are planning to conduct approximately 2,000 metres of drilling.”
The Oculto deposit on the Diablillos property is a high sulphidation epithermal deposit, as confirmed by the
hydrothermal breccia and vuggy silica textures as well as the silica, alunite, clay, and pyrite alteration mineral
assemblages. Multiple steeply dipping alteration zones with breccias and dacite intrusives have been mapped
at surface on the Diablillos property (Figure 1). Since h igh sulphidation systems tend to have much better
depth extent than low sulphidation systems, there is a much greater potential for high grade, gold -rich
mineralization in structurally controlled breccia zones in the basement underlying silver rich mineralization in
the overlying volcanics. In the case of Oculto, there ha s been very l ittle drilling into the basement below the
volcanics or into the breccia zones in basement exposed at surface lateral to the Oculto deposit.

The newly identified group of breccias lies immediately east of the main Oculto deposit (Figure 2) and includes
the Nebulosa, Concepcion, and Enigmatica breccia zones. These breccias have identical style and alteration to
the breccias that host high grade gold mineralization in the basement beneath the Oculto deposit as well as to
a surface analogue occurrence directly to the south of Oculto . The breccias have surface expressions and
internal textures that indicate that they are structurally controlled, planar to lenticular, bodies up to 40 metres
wide and 500 metres long.

A hydrothermal breccia of this style was intersected in granite basement below the Oculto deposit in historic drill
hole DDH-97-007A, which intercepted
1.1m grading 90.74g/t Au from 215.4m
down hole in brecciated granite with
strong silica alteration (Figures 3 and 4) .
Zones of vuggy silica alteration on either
side of the breccia added substantial
volume at attractive grades, such as 5.4m
grading 6.54g/t Au and 4.1m grading
9.89g/t Au. The overall average, including
the breccia and vuggy silica alteration
zones, was 10.6m grading 16.67 g/tAu and
39.22g/t Ag. Similar grades and widths
have been reported from historical drilling
at a surface analogue south of Oculto.

Exploring these breccias requires a new drill strategy designed to drill across the strike of individual breccia bodies.
The majority of the breccia bodies strike NNW with near vertical dips. This orientation is sub parallel to most of the
previous drilling in this area and, as a result, none of the breccia bodies have been tested by historical drilling.

A preliminary exploration drill program of 2,000m is planned to test the five best breccia zones. The holes are
designed to intersect the breccia bodies at a depth of 100 -150m which is the shallowest known level of gold
mineralisation in other parts of the Diablillos deposit. The holes are designed with a dip of -70°. This will ensure a
broad intersection of the steeply dipping breccias without the risk of deflecting the drill hole. The drill holes are
aimed below the thickest parts of the breccias with the strongest silica alteration since intensity of silica alteration
shows a strong correlation with gold grade in breccias previously intersected in the basement below the Oculto
deposit. If these holes intersect significant gold mineralisation as expected, a substantial drilling program will be
required to fully define the new resources.
