Oro Verde Limited (ASX: OVL) (“Oro Verde” or “the Company”) is pleased to announce that surface sampling of new areas at the Topacio Gold Project, located in southeastern Nicaragua (Figure 1), has uncovered additional high grade targets for future drill testing.
The Mauricio vein strikes roughly east-west and is located outside the existing resource area, near the Isabella and Su Majestad veins (Figure 3). The Company’s first pass surface mapping of the 600m long vein identified highly encouraging vuggy and drusy quartz veins, typical of low sulfidation epithermal vein systems. Sampling on the vein returned gold (Au) grades up to 7.5 g/t Au .
Recent high grade results from the Isabella vein of up to 21.3 g/t Au and 18g/t silver (Ag) - from a brecciated quartz vein – as reported in October[1] , were confirmed by the latest sampling with results up to 6.8 g/t Au.
In addition, a 3.9m trench sample across the Dispute vein returned an average of 4.9 g/t Au with a 1.4m section reaching 9.2 g/t Au on the vein margin.
Oro Verde’s Managing Director, Mr. Trevor Woolfe commented, “We continue to receive excellent results from Topacio. High grade gold results from the Mauricio vein add to a growing cluster of highly prospective veins including Isabella and Su Majestad to the east of the Topacio vein that, when drilled, are expected to expand the Topacio resource. New gold mineralisation in the northeast at Tamara and Palmita also shows promise outside the existing resource area.”

SURFACE SAMPLING
A total of 62 samples were collected from Oro Verde’s latest field campaign, which focused on three potential target zones, principally outside the existing Topacio Gold Project resource area (Figure 2):
-
Isabella-Mauricio Zone : a system of W-NW trending quartz veins east of the main resource
-
Tamara-Palmita Area : a group of veins 1.5-2 km to the northeast of the Topacio resource area
-
Topacio West Zone : veins at the western edge of the resource and boulders further west
Isabella-Mauricio Zone
The Isabella vein has a northwesterly strike and may be discontinuously linked to the high grade Su Majestad vein (Figure 3). A high grade result of 21.3 g/t Au - from a brecciated quartz vein – reported in October[2] , exceeded previous results that were <2.5 g/t Au. Latest sampling has identified further high grades with a zone of vuggy quartz veining returning 6.8 g/t Au (Sample #48710).
Approximately 300m to the southwest of Isabella lies the east-west trending Mauricio vein. This vein is almost 600m in length and is a possible splay off the Isabella-Rebeca line of veins (Figure 4). Initial sampling consisted of three rock chip samples with vuggy/drusy epithermal vein textures – often indicative of a low temperature epithermal system – all of which were mineralised in the range 1.1 to 7.5 g/t Au . These samples continue to enhance the potential of the vein system directly to the east of the Topacio resource area (Figure 2).

Sample 48681 7.54 g/t Au

Sample 48683 1.16 g/t Au
Tamara-Palmita Area
The Company continues to explore new areas of the 93 km[2] Topacio concession that could provide additional drill targets for the 2016 work program. A number of veins have been identified approximately 1.5 km to the northeast of the Topacio resource area, including the Tamara and Palmita veins (Figure 3).
These veins show similar epithermal vein and breccia textures to those at Topacio. Initial sampling has been encouraging, with gold grades up to 2.3 g/t Au at Tamara East (#48709) and up to 3.0 g/t Au at Palmita (#48716). Manganese (up to 5,025 ppm) is also prominent at Tamara – a similar signature to the main Topacio resource veins. Tamara is along the same northeasterly trending vein set including the mineralised Topacio and Mico veins (Figure 3).
The Buena Vista stockwork style mineralisation, a further 4 km to the northeast (Figure 3), is also along that same trend, providing encouragement for a potential connection between the two styles of mineralisation. The intervening area is relatively unexplored to date.
The Topacio vein has a discontinuous strike length of at least 3.5 km (Figure 4). The far eastern extension of the Topacio vein in this same area near Tamara (Figure 4) was also sampled. The vein is anomalous in gold and silver, albeit at lower levels (#48717-22)(Table 1).
Topacio West Zone
A number of samples were collected at the western extremity of the resource area (Figure 2) to test the potential for extensions. On the Topacio vein, three mineralised samples returned values up to 5.9 g/t Au (Figure 3).
An old trench across the Dispute vein was sampled with individual results of up to 9.2 g/t Au over a width of 1.4m. This sample is part of a broader mineralised section of 3.9m at 4.8 g/t Au (Samples #48662-64).
A zone of bleached and silicified volcanic boulders, sometimes with fine quartz veinlets, approximately one kilometre further to the west (Figure 4), is interpreted as a layer of unmineralised altered volcanic cap rocks overlying the mineralised vein horizon.

BACKGROUND
On 25 February 2015, Oro Verde announced the positive due diligence and acceptance of an Option to Purchase Agreement over the high grade Topacio Gold Project, located in southeastern Nicaragua (Figure 1). The project boasts 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[2] .
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. 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.

About Oro Verde Limited: Oro Verde Ltd is a mineral exploration company focused on identifying and developing significant gold projects in Central America, particularly Nicaragua. Oro Verde holds an Option to Purchase Agreement on the Topacio Gold Project in Nicaragua that currently contains a NI43-101 compliant Inferred Mineral Resource of 340,000 ounces of gold. Oro Verde also holds 100% of the early stage San Isidro Gold Project, also in Nicaragua, located adjacent to the 2.3 million ounce La India gold project.

Previous exploration of the Topacio Gold Project has consisted of mapping, stream sampling, rock chip sampling, soil sampling, trenching, diamond drilling and feasibility |
