STRONG GOLD ANOMALIES IN SOILS AT TOPACIO
HIGHLIGHTS
-
Strong gold anomalies exceeding 1,000ppb (or 1 g/t) generated from soil geochemistry at Topacio
-
An expanded gold target zone has been identified around the Topacio resource area
-
The Rebeca Zone to the east of the Topacio resource developing as a potential drill target with gold-in-soil anomalies up to 209ppb and coincident arsenic and antimony anomalies
-
Further analysis of results together with geophysical data to follow
Oro Verde Limited (ASX: OVL) (“Oro Verde” or “the Company”) is pleased to announce that it has outlined new gold (Au) anomalies from the recently completed soil sampling program across the Topacio Gold Project, located in southeastern Nicaragua (Figure 1).
The soil geochemistry program 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] .
Individual assay results reached >1,000ppb Au (or >1 g/t Au), indicating that some sample results exceeded the upper limit of detection of the analysis method used. Sample locations were relatively wide spaced on a 400m x 400m grid designed to provide broad coverage across the entire concession but, importantly, 14 samples returned assay results with more than 10x background gold levels and highlight a number of potential new target zones outside the known Topacio gold resource area.
Oro Verde’s Managing Director, Mr. Trevor Woolfe, commented “The soil sampling and multi-element geochemistry program has provided us with a valuable tool in the assessment of the Topacio Gold Project. Gold results received highlight the potential for expansion of the existing gold resource, with some results exceeding 1g/t Au and a number of new anomalous areas defined. Planning is advanced to prioritise follow up on these new targets.”

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 drilling scheduled to commence in the second half of 2016. The Stage 1 program includes:
-
Detailed geological mapping and sampling
-
Concession-wide 400m x 400m grid soil sampling program
-
Airborne geophysics – magnetics and radiometrics
SOIL SAMPLING PROGRAM
The extensive soil sampling program was carried out by Oro Verde’s local geologists and reviewed in conjunction with the Newcrest technical team. A total of 567 soil locations were sampled on a 400m x 400m offset grid (Figure 2), and sent for multi-element analysis along with an additional 79 samples (field duplicates and standards), as well as laboratory standards, duplicates, repeats and blanks completing the QA/QC process. The team worked diligently to collect all except three of the planned samples, due to access difficulties.

Anomalous Gold Targets
The soil sampling program identified at least three zones of strong gold anomalism outside of the known Topacio gold resource area (Figure 3). These three zones are characterised by multiple results in each zone that are significantly higher than background gold levels.
Zone 1 – Northwest Anomaly
Zone 2 – Northeast Topacio Extension Zone 3 – Rebeca Zone
==> picture [596 x 43] intentionally omitted <==

1. Northwest Anomaly
The Northwest gold-in-soil anomaly is characterised by a cluster of anomalous gold results on the northwestern side of the central Mico vein (Figure 3). Maximum values within this zone included a result that reached >1,000ppb Au - the upper limit of detection (sample 73902) - as well as sample 73938 that recorded 893ppb Au, between the central Mico and Chicago veins, and a sample near the Mico vein that assayed 329ppb Au (73951). Previous reconnaissance mapping and rock chip sampling by Oro Verde in this area during 2015 identified a zone of cross cutting veins with elevated gold results. This zone includes the Chicago, Gallina and Celedonio veins.
2. Northeast Topacio Extension
While previous drilling has focused around the exposed veins at Topacio (including the Dos Amigos, Dispute and Brasil veins), the along strike extension of this area has received little attention from drilling (Figure 3). The soil sampling has highlighted four key anomalies within this 2.5km long northeasterly trending zone . At the southwestern end of the anomaly, a sample from the northeastern end of the Brasil vein reached >1,000ppb Au (74903) - the upper limit of detection. In the centre of this zone, a sample located close to the Topacio NE extension vein returned 274ppb Au (74862) and in the northeast of this zone, two adjacent samples returned 202 and 197ppb Au (74834 and 74821, respectively), in the vicinity of the intersection of the Topacio NE extension vein with a cross cutting vein. The key to these anomalies is likely to be where cross cutting NW-SE trending structures intersect with the more prominent NE-SW trending veins.
3. Rebeca Zone
To the east-southeast of the Topacio resource area, lies the third significant anomalous gold zone, identified here as the Rebeca Zone. It is a broad area containing a number of veins (including Rebeca, Isabella, Andres, La Palmita and Chocorron) predominantly striking NW-SE and flanking what is interpreted to be an overlying silica cap of El Sahino (Figure 3). Veins from the Rebeca Zone have typically recorded lower average rock chip gold grades than the veins further west-northwest, however have been interpreted to represent a higher level within the epithermal system. This is supported by the presence of the El Sahino silica cap lying to the south. It is interesting to note that the gold-in-soil anomalies of the Rebeca Zone appear to abut the silica cap, and the gold geochemistry in the cap is consistently at background levels – this is not uncommon in epithermal systems and may indicate a buried mineralised system. Anomalous gold values from the soil sampling in the Rebeca zone include 248 and 209ppb Au (74908 and 74867, respectively).
The prospectivity of the Rebeca Zone as a possible drill target is enhanced by the coincidence of strong arsenic (As) (up to 791ppm) and antimony (Sb) (up to 77ppm) anomalism, as shown in Figure 4. These elements can be representative of “upflow” or “outflow” zones from a buried source in an epithermal system. Previous mapping has also determined that the textures of quartz veins in the Rebeca Zone are indicative of the upper levels of an epithermal system.

At least two more zones display anomalous gold results, however are characterised by either multiple lower level anomalous results or by isolated very high gold results.
Zone 4 – Southern Anomaly
Zone 5 – Buena Vista Zone
4. Southern Anomaly
A single, highly anomalous gold result was obtained from the soil sampling near the southern tenement boundary, on the western flank of the El Sahino silica cap (Figure 3). The analysis of sample 74978 retuned 226ppb Au, whilst surrounding samples were at background levels of 4ppb. The significance of this result will require additional ground follow up, to understand the relationship with the nearby silica cap.
5. Buena Vista Zone
The Buena Vista target was identified by Oro Verde during reconnaissance mapping and sampling in 2015, when rock chip samples displaying stockwork vein textures returned grades up to 3.35g/t Au and 50g/t silver (Ag). While further detailed mapping is required to understand this zone, the soil sampling has provided encouragement with multiple low level (21-41ppb Au) gold results (Figure 3). Background gold levels in this area of the concession are generally less than 10ppb Au.
Next Stage
Planning is well advanced to incorporate these soil results with recent field mapping and pending geophysical results, with a view to firming up and prioritising targets for drilling as soon as practicable.
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[2] . 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.

No drilling was undertaken in the current program. Soil samples were generally humid and hence were subjected to drying to 60 degrees C at the sample preparation stage in the laboratory. Sample prep techniques used by the laboratory were considered appropriate for regional style soil samples. Field duplicates were submitted each 20th sample in the sequence. The laboratory also conducted internal repeats at variable intervals between each 10 to 20 samples (average was every 16 samples). Both field duplicates and laboratory repeats were within acceptable ranges. A number of samples were selected from the first batch of soil samples and inserted every 30th sample within subsequent batches to determine the consistency of analyses between batches. A sample size of 1.5 to 2.5kg was collected and considered appropriate and representative for the grain size and style of mineralisation beingexplored. |

ACME Laboratories (Bureau Veritas) (Managua and Vancouver) were used for all analysis work carried out on the soil samples. The laboratory techniques below are for all samples submitted to ACME and are considered appropriate for the style of mineralisation expected at the Topacio Gold Project: oDry at 60degC oSS80 – dry at 60degC sieve 100g to -80 mesh oSLBHP – sort label and box pulps for delivery to Vancouver oFA130 - Fire assay fusion Au Pt Pd by ICP- MS (30g) oMA200 – 4 Acid digestion ICP-MS analysis of 45 elements (0.25g) No other analytical tools used in the current program Field duplicates were submitted every 20 samples. Selected samples from thefirst batchof soil analyses were re-submitted with each subsequent batch to maintain control over the variability of analyses in different batches. 60g packets of two separate commercialstandards(OREAS 45d and OREAS 45e) were purchased from ORE Pty Ltd (Melbourne) and inserted alternately in the sample string each 10 samples. The lab undertookduplicate analysisat a ratio averaging 1 in 16 samples. Whereover range resultswere obtained, it was not deemed necessary to repeat the individual samples with alternative methodologies for more accurate readings. The lab undertook tests on in-house standards and blanks. Results were deemed to be within the expected accuracy levels. No external laboratory checks have yet been undertaken. |

Significant results have been reviewed by company technical personnel as well as senior geochemists and geologists from Newcrest Limited. Selected significant results may be subjected to follow up soil sampling on a closer spaced grid at a later date. No drilling was undertaken in the current program, hence twinned holes are not relevant. Descriptions of each sample location and each sample were recorded by the geologist and technician in the field. This data was transferred daily from field notebooks and GPS devices into an Excel database. Analytical data has been uploaded directly from laboratory files into a GIS system for verification of data and locations. No adjustments of assaydata were undertaken. |

Garmin Oregon 600 and Garmin eTrex Vista HCx hand-held GPS units were used to define the location of the samples. The GPS was left at the sample point for a minimum period of 2 minutes to obtain a steady reading. Sample locations are considered to be accurate to within 5m. Grid system used is UTM Zone 16 with datum NAD27 Central. A good topographical base has been produced using orthorectified aerial photos with 5m contours. Any variability in GPS elevation measurements during sampling can be projected onto the topographical base. |
