Marengo Provides First Results from Drilling Campaign and Update on Financial Arrangements

24.10.2013  |  Marketwired

First Hole at Dimbi 2013 Intersects Significant Widths of Near-Surface, Higher Grade Copper-Molybdenum-Gold: Yandera Project, PNG

Significant intersection of 90m @ 0.53% Cu including 27m @ 0.71% Cu

Peak assay of 3m @ 1.95% Cu: remaining assays for final 36m of core due within a week

Results support current drilling strategy of targeting a potential starter pit at Dimbi

PERTH, WESTERN AUSTRALIA--(Marketwired - Oct 24, 2013) - Marengo Mining Ltd. (TSX:MRN)(ASX:MMC)(POMSoX:MMC) ("Marengo" or the "Company") is pleased to provide this update on the first results from its recently announced drilling campaign and the status of its financing discussions.

Initial Drilling Result

Marengo is pleased to advise that the first diamond drill hole of its 2013 campaign targeting the near-surface Dimbi Zone within the Yandera Central Porphyry System at its flagship Yandera Copper-Molybdenum-Gold Project in Papua New Guinea has returned encouraging results.

A 2,000m (10-hole) diamond drilling campaign commenced at Dimbi in mid-September with the objective of identifying near-surface resources with the potential to delineate a starter pit for the Yandera mining operation which could enhance the Project.

The new drill-holes have been designed to target projections of interpreted north-east striking mineralised structures in the hanging wall of the Dimbi Fault, a major north-westerly striking structure which dips to the north-east and bounds the Dimbi Zone on the south-west.

This early fault established a conduit for mineralised fluid flow into the Dimbi Zone, along a later set of north-east trending faults. The current drill holes have been carefully sited to test these recently mapped mineralised structures as well as up-dip projections of elevated copper intercepts at depth in several nearby existing drill-holes.

The Dimbi drilling program has been progressing well with three holes (YD 551, YD 552 and YD 553) completed to date and the fourth hole currently in progress. The first batch of assay results has been received for the first hole, YD551, for the interval from surface to 162m down-hole, as summarised below:

YD551 (Dimbi)
Collar co-ordinates 292715E, 9365998N; Azimuth 150° (AMG) dip -60°
From (m) To (m) Width (m) Cu % Mo ppm Au g/t Ag g/t
69 159 90 0.53 60 0.05 2.5
Within this broad Intersection
105 132 27 0.71 121 0.09 3.5
120 123 3 1.95 398 0.15 9.7
6 18 12 140
114 129 15 187
15 18 3 0.58
36 81 45 2.6
69 81 12 3.8

The hole also returned significant intersections of molybdenum and gold including a 150m intersection grading 65ppm Mo (from 6 to 156m down-hole) with a peak intersection grading 398ppm Mo; and 21m grading 0.22g/t Au (from 6 to 27m down-hole), with a peak result of 3m @ 0.58g/t Au.

Assays are still awaited for the remainder of the hole, from 162m to 197.6m, and these are expected to be received within a week. Copper mineralisation continues to the end of the hole.

The other drill holes completed in the current campaign at Dimbi and for which analyses are awaited are also encouraging.

YD 552 has wide moderately mineralised intervals throughout. Within these intervals there are a number of intersections with veins of chalcopyrite to 5cm at various depths including 143.5m and within a major fault zone (the target of the hole) at 207.5m. At 61.8m a 20cm vein of pyrite and chalcocite was intersected.

YD 553 appears to be mineralised throughout, and is noteworthy as having a strongly mineralised 9m interval (54m to 63m) containing bornite as the principal copper mineral (note that pure bornite contains 63% copper compared to chalcopyrite, 34% copper). This bornite interval resembles those also seen in some Imbruminda Zone drillholes. Deeper in the hole are chalcopyrite and pyrite veins, including at 168m (30cm), and a 90cm interval of closely spaced chalcopyrite veins to 3mm each (177.5m to 178.4m).

YD 554 is noteworthy for the incidence of scattered primary native copper smears and dendrites within the interval 20m to 63m. A 7m major structure is present from 86.5m to 93.4m with moderate chalcopyrite, bornite and molybdenite as veins and fracture fill. Bornite is noted as disseminations and fracture smears throughout the hole.

Marengo's President & CEO, Mr. Les Emery, said he was pleased and encouraged by the early results from Dimbi, with the first hole intersecting a broad zone of mineralisation with an average grade for the sections for which assays have been received, significantly above the current Mineral Resource grade at Yandera.

"This is a significant result for Yandera, providing strong early encouragement that the current drilling campaign can outline an extensive near-surface zone of higher grade material at Dimbi - with important strategic implications for the overall Yandera development.

"Dimbi has received relatively less attention as an exploration target in the past compared with the other zones which make up the Yandera Central Porphyry, mainly because of the challenging terrain in this area," Mr. Emery continued.

"The drilling so far has confirmed the very encouraging results from detailed (scale 1:2,500) tape and compass-based field mapping carried out earlier this year over the Dimbi Zone and gives us confidence that the program is appropriately targeted and represents the right strategy for the Yandera Project at this time. We look forward to receiving further results from the current drilling campaign over the coming weeks and months."

Financing

Marengo has entered into discussions regarding the $10 million loan provided by the Sentient Group, in advance of the December 31, 2013 maturity date for this facility. Discussions have been positive to date, and we expect to have a further update regarding these discussions in the coming weeks.
