GEOPHYSICS HIGHLIGHTS NEW TARGET ZONES AT TOPACIO
HIGHLIGHTS
-
Geophysical anomalies from the recent airborne survey highlight new gold target zones
-
The Rebeca Zone includes a number of subparallel vein structures with potential concealed lateral continuity up to 3 kilometres in length, coincident with gold-in-soil anomalies
-
New epithermal vein targets inferred from linear zones of magnetic depletion
-
Radiometrics identify alteration zones located along the Mico vein and also associated with the Rebeca Zone veins
-
Detailed mapping and infill soil sampling is planned to refine the targets for drilling
Oro Verde Limited (ASX: OVL) (“Oro Verde” or “the Company”) is pleased to announce that the recent heliborne geophysical survey at the Topacio Gold Project, located in southeastern Nicaragua (Figure 1), has identified new target zones for possible drill testing.
The geophysical survey is part of the Stage 1 exploration program of the Farm-In Agreement between Newcrest International Pty Ltd, a wholly owned subsidiary of Newcrest Mining Limited (ASX: NCM) (“Newcrest”) and Oro Verde, executed at the end of November 2015[1] .
The high quality magnetic and radiometric data has provided valuable structural and alteration data across the full concession. Interpretation of the magnetic data indicates that the Rebeca Zone, southeast of the Topacio resource, could host NW-SE trending concealed veins with up to 3 kilometres of strike extent. This zone is broadly coincident with a gold-in-soil anomaly recently reported by the Company[2] .
A follow-up field program, including detailed mapping and infill soil sampling, is currently being implemented to refine this target area, with drill testing expected to follow.
Oro Verde’s Managing Director, Mr. Trevor Woolfe, commented “Our understanding of the geological characteristics of the Topacio Gold Project have improved significantly with the completion of the concession-wide geochemistry (soils) and geophysical surveys. We are now focused on refining the priority targets generated, with the objective of drill testing the best targets and, ultimately, expanding the gold resource.”

AIRBORNE GEOPHYSICAL PROGRAM
The Stage 1 airborne geophysical survey over the Topacio Gold Project, located in southeastern Nicaragua (Figure 1), was completed successfully in July, without safety or community incidents. With the survey being undertaken during the wet season, Oro Verde, Newcrest and New Sense Geophysics (NSG)(of Canada) worked tirelessly and closely, with assistance from the Nicaraguan Air Force (FAN), to ensure that a rigorous safety overlay was in place, not only for the operational aspects but also for the local communities and landholders.
A total of 1,021.3 line kilometres were flown during the helicopter-borne survey, which included magnetics and radiometrics over a survey area covering the entire 93km[2] of the concession.
HIGHLIGHTS OF THE GEOPHYSICAL DATA INTERPRETATION
Three first order target areas have been delineated (see Figure 2):
-
Rebeca Zone - Linear NW-SE features (high amplitude anomalies) in magnetics highlight a number of veins, likely related to brittle failure, with potential lateral extent up to 3km. These features have not previously been drill tested.
-
Myra-Lirina Veins – magnetic depletion along structures associated with mapped veins, similar to the nearby Rebeca Zone.
-
La Palmita Structure – This is another NW-SE trending structural zone – in proximity to an interpreted intrusive contact zone - to the north of the Rebeca Zone that may be related to a concealed vein zone. It may be a continuation of the La Palmita vein, which has been mapped at the NW end of this trend.

Figure 2 Topacio Project – Magnetic data
Two second order target areas have been identified (see Figure 2):
-
Two additional NW-SE trending features have been highlighted by the magnetics to the north and northeast of the Topacio-Rebeca vein areas. Their signatures suggesting possible concealed vein zones. Veins have not been mapped along these two features previously.
-
The magnetic signature of an area to the NW of the Topacio resource indicates the possibility of a previously unidentified vein zone. No veins are currently mapped within this area. The area is along strike to the NW of the Rebeca vein.
Two large remanently magnetised bodies have been identified in the SW and SE of the concession (Figure 2), interpreted as representing large intrusive bodies.
The radiometric data (Figure 3) displays some significant zones of potassium-rich alteration present in the Topacio Project area:
-
Rebeca Zone (dashed area on Figure 3) – Strong pink shading in the area of the Rebeca Zone and also to the NE of the Topacio Vein, indicates prominent potassium-rich alteration zones.
-
Mico Vein – The pink zones along parts of the Mico Vein indicate potassium-rich alteration associated with the emplacement of the vein. A magnetic depletion zone on part of the Mico Vein (Figure 3) maybe intrusion related or a large alteration zone.

Next Stage
The key objective of the Stage 1 exploration program, which commenced in January 2016, is to identify highly prospective vein, alteration, geochemical, geophysical and structural targets for drill testing, scheduled to commence in the second half of 2016. The Stage 1 program, which has successfully achieved its objectives, included:
-
Detailed geological mapping and sampling
-
Concession-wide 400m x 400m grid soil sampling program
-
Airborne geophysics – magnetics and radiometrics
A follow up program of detailed mapping around the Rebeca Zone, combined with closer spaced soil geochemical sampling (localised - down to a 200m x 50m grid), is currently being implemented with a view to refining and prioritising targets for drilling as soon as practicable.
Associated environmental studies required for drilling activities are also being initiated.

TOPACIO PROJECT BACKGROUND
Oro Verde holds an Option to Purchase Agreement over the high grade Topacio Gold Project, located in southeastern Nicaragua (Figure 1). Details can be found in the announcement to the ASX dated 27 February 2015[3] . The project contains a historical NI 43-101 (Canadian standard, similar to JORC) compliant Inferred Resource of:
2,716,176 tonnes at 3.9 g/t gold, containing 340,345 ounces of gold, at a 1.5 g/t gold cut-off
National Instrument 43-101 (“NI 43-101”) is a national instrument for the Standards of Disclosure for Mineral Projects within Canada and as such this estimate is a foreign estimate and is not reported in accordance with the JORC code (Australia). A competent person has not done sufficient work to classify the foreign estimate as mineral resources in accordance with the JORC code and it is uncertain that following evaluation and/or further exploration work that the foreign estimate will be able to be reported as mineral resources in accordance with the JORC code.
