ASX Announcement
12 October 2016
HIGH GOLD GRADES HIGHLIGHT MULTIPLE TARGETS AT TOPACIO
HIGHLIGHTS
-
High grade gold results received from previously unsampled areas of Topacio
-
Highest grade rock chip sampling results include:
-
Lone Star vein 50.5 g/t Au (sample #48897)
-
• Canada vein 42.8 g/t Au (sample #48875) • Toronto vein 38.7 g/t Au (sample #48879) • Pispireta vein 32.2 g/t Au (sample #48846)
-
Highlights the presence of additional vein targets outside the Topacio resource area
-
Currently completing infill soil sampling at the Rebeca Zone to refine drill targets - assays pending
Oro Verde Limited (ASX: OVL) (“Oro Verde” or “the Company”) is pleased to announce that very high grade gold (Au) results have been received from recent rock chip sampling of epithermal vein targets at the Topacio Gold Project, located in southeastern Nicaragua (Figure 1).
While current field activities are concentrating on infill soil sampling at the Rebeca Zone to refine targets for drilling, where the objective is a potential buried low sulphidation epithermal system, these rock chip results highlight the existence of numerous additional targets outside the existing Topacio gold resource.
Maximum gold and associated silver (Ag) grades from these results are as follows (refer full Table 1):
-
Brazil 9.95 g/t Au; 11.7 g/t Ag • Pelos de Oro 4.02 g/t Au; 5.6 g/t Ag
-
• Canada 42.8 g/t Au; >200 g/t Ag • Pispireta 32.2 g/t Au; 18.2 g/t Ag
-
Dispute 21.4 g/t Au; 15.1 g/t Ag
-
Su Majestad 16.9 g/t Au; 145.9 g/t Ag
-
Dos Amigos 9.07 g/t Au; 39.2 g/t Ag
-
Tamara 5.42 g/t Au; 11.3 g/t Ag
-
Lone Star 50.5 g/t Au; 70.1 g/t Ag
-
Lone Star 50.5 g/t Au; 70.1 g/t Ag • Topacio 12.5 g/t Au; 15.0 g/t Ag
-
• Mico 21.4 g/t Au; 39.1 g/t Ag • Toronto 38.7 g/t Au; 52.3 g/t Ag • Mico SE Split 7.15 g/t Au; 19.0 g/t Ag
Oro Verde’s Managing Director, Mr. Trevor Woolfe, commented “While our current field activities are focused on infill soil sampling to define drill targets in the Rebeca Zone, I am extremely encouraged by these latest results that include some very high gold grades from areas of previously limited access. These results highlight the presence of additional quality gold targets associated with exposed quartz veins at Topacio. Our current activities bring Oro Verde closer to finalising and prioritising targets for drilling.”

TOPACIO ROCK CHIP SAMPLING
Exploration activities at Topacio during 2016 have included a concession-wide 400m x 400m soil sampling grid, as well as detailed vein mapping and associated rock chip sampling. These programs form 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 soil geochemistry results were released on the ASX in August[2] and demonstrated that at least three priority zones have been identified with anomalous gold geochemistry. These three zones (Figure 2) were identified as the:
-
Northwest Anomaly;
-
Northeast Topacio Extension; and
-
Rebeca Zone
While the Rebeca Zone is currently the focus of an infill soil sampling program to refine and prioritise targets for drilling[3] , recent vein texture mapping and rock chip sampling was undertaken along the complex vein systems corresponding to the Northwest Anomaly and the Northeast Topacio Extension gold-in-soils anomalies, as well as the Topacio Resource Area (Figure 2).
High gold grades (Table 1) have been received from at least 13 different veins in this sampling campaign (Figures 3 and 4) and highlight the presence of multiple vein targets that may be considered for follow up drilling.

Figure 3 Topacio Project – latest rock chip sampling results (gold) [Refer Figure 2]
Additional rock chip sampling has also been undertaken in the Rebeca Zone during the current infill soil sampling program. The Rebeca Zone is thought to represent the upper levels of a buried low sulphidation epithermal system and, as has been shown in previous rock chip sampling, can be expected to return lower gold grades. Results are expected over coming weeks.

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[4] . 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.

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 to acquire 100% of the Topacio Gold Project in Nicaragua that contains a NI43-101 compliant Inferred Mineral Resource of 340,000 ounces of gold. A US$7.9 million 5 year farm-in agreement was signed on November 25, 2015 with a subsidiary of global gold major - Newcrest Mining Limited (ASX: NCM) – to jointly explore for multi-million ounce gold deposits at Topacio. 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.
