Oro Verde’s CEO, Mr. Doug Bright, commented “We are very pleased with our latest surface trench sampling results which include some very high gold values. As anticipated, our results continue to confirm the high gold grade potential of this large vein system. We are seeing excellent gold grades in good widths and are optimistic that our latest drilling program – to test beneath these quartz vein outcrops – will produce encouraging intercepts. Drill locations have been chosen and sites prepared with commencement of drilling imminent.”
BACKGROUND – RECENT WORK
Following very encouraging high gold results from the Phase 2 trenching and the follow-up Phase 2 diamond core drilling (ASX 20[th] July, 1[st] and 14[th] August, 2017), Oro Verde announced on 28[th] September, 2017, the commencement of a third phase of surface trenching and channel sampling in an accelerated and expanded program to test a greater number of the multiple vein targets identified by previous mapping and sampling as carrying significant gold grades.
This third trenching program was completed in December, 2017, amounting to 40 trenches for a total of 860.3 linear metres of trenching and 750 channel samples to confirm the grade, dip and widths of the veins and to finalise drill-hole orientations of a Phase 3 diamond core drilling program.

Large quartz veins were intersected in 38 of the 40 trenches, which were excavated perpendicular to the strike of the veins to depths sufficient to expose in situ bedrock. All trenches were mapped and sampled by Oro Verde personnel.
Samples were sent to the Inspectorate Laboratory in Managua for sample preparation. Pulps were then sent internally by the laboratory to its parent Bureau Veritas Laboratory in Vancouver for analysis. All samples were analysed for gold by fire assay/ICP-ES (FA330-Au) and for 45 elements by four-acid digest ICP-MS (MA200).
Nine distinct quartz veins in the central Topacio district were tested by this third and final group of 13 trenches in this phase (no’s 043 – 055). Analyses from all 13 trenches demonstrate good gold responses; six trenches yield significant gold-bearing intervals, as shown in following Table 1a, and a further 7 show other meaningful gold intervals, shown in Table 1b:

TOPACIO PROJECT BACKGROUND
Oro Verde holds an Option to Purchase Agreement over the historically-reported high-grade Topacio Gold Project, located in south-eastern Nicaragua (Figure 4). Details can be found in the ASX announcement dated 27 February 2015[1] . The project contains a historical NI 43-101 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 in accordance with the JORC code (Australia). A defined Competent Person has not yet undertaken sufficient work to classify this foreign estimate as a mineral resource in accordance with the Australian JORC code and, at this stage, it cannot be stated with certainty that, following evaluation and/or further exploration work, the foreign estimate will be able to be reported as a mineral resource in accordance with the JORC code.
