Alder Trenching Returns Exceptional Results at Rosita Project, Northeast Nicaragua

09.01.2013  |  Marketwired
5.21% copper, 4.40 g/t gold and 144.01 g/t silver over 12.1 metres

7.48% copper, 2.36 g/t gold and 316.13 g/t silver over 6.5 metres


TORONTO, ONTARIO -- (Marketwire) -- 01/09/13 -- Alder Resources Ltd. ("Alder" or the "Company") (TSX VENTURE: ALR) is pleased to provide results from additional trenching at the Tipispan porphyry copper-gold prospect within the Company's Rosita Project in northeast Nicaragua (Figure 1). Results include 5.21% copper ("Cu"), 4.40 grams per tonne ("g/t") gold ("Au") and 144.01 g/t silver ("Ag") over 12.1 metres in Trench 13 and 7.48% Cu, 2.36 g/t Au and 316.13 g/t Ag over 6.5 metres in Trench 12 (Figure 2). In addition, a second mineralized interval in Trench 12 returned 2.66 % Cu, 0.28 g/t Au, 113.11 g/t Ag, 0.16% lead ("Pb") and 1.70% zinc ("Zn") over 6.0 metres. The mineralization in these zones is open along strike and to depth.

Company President and CEO, Joseph Arengi, states: "The exceptional metal values from this discovery are highly significant and the Company believes they represent the margins of a well mineralized porphyry-type copper-gold-silver system. Additionally, these zones of shallow mineralization add considerable near term upside potential to Alder's current mineral resources. Our exploration efforts continue to demonstrate the highly prospective potential of the Rosita project."

The interval in Trench 12 is an average from sampling along the north and south walls of the trench. Copper mineralization occurs as copper oxides hosted by altered intrusive rocks and preliminary interpretation suggests it occurs in three parallel zones along a 200 metre corridor (Figure 2). A nearby core hole drilled by Calibre Mining in 2010 intersected porphyry-style mineralization that returned 0.42% Cu, 0.02 g/t Au and 7.00 g/t Ag over 50.0 metres. Additional trenching in this area is ongoing.

A fourth mineralized zone, located 200 metres southwest of trenches 10 to 14, was intersected by a core hole drilled by Calibre that returned 0.51% Cu, 0.25 g/t Au and 10.41 g/t Ag over 11.5 metres in a highly altered intrusive rock. Rock sampling by Alder in this area returned several samples containing more than 1 g/t Au with up to 12.33 g/t Au in the vicinity of artisanal miner activity. Alder plans to target the source of these mineralized intrusions with a series of trenches and detailed soil sampling.

The Tipispan prospect is located within the Bambana area which is four kilometres northwest of the past producing Santa Rita pit and one kilometre northeast of the T3 zone (Figure 1) where trenching has returned up to 3.32% Cu, 0.22 g/t Au and 37.55 g/t Ag over 12.0 metres and drilling has returned up to 1.74% Cu and 16.64 g/t Ag over 18.0 metres in an exotic Cu-oxide zone.

Bambana Porphyry Targets

In addition to the targets discussed above, an Induced Polarization geophysical survey completed in 2012 has identified a series of strong chargeability anomalies that conform to a circular feature interpreted from a magnetic survey. Chargeability anomalies suggest areas of disseminated sulphide mineralization that could represent porphyry-type exploration targets. In addition to the anomaly at T3, an 800 metre by 500 metre anomaly occurs in the north central part of the Bambana area and an approximate 1,500 metre by 1,000 metre anomaly has been delineated in the southeast corner of the Bambana area. The latter coincides with the Zopilote prospect, drilled in the 1960s, with reported historic reserves of 176,000 tonnes of oxide material grading 0.90% Cu and 79,000 tonnes of sulphide material grading 0.97% Cu (referenced in a map by A. Rivera, 1977).(1) Gold and silver values are not reported for this zone.

(1)This historical estimate was not prepared in accordance with currently accepted guidelines for the preparation of mineral resources and mineral reserves, does not comply with NI 43-101 and should not be relied upon. Although the historical estimate is relevant to recognizing potential, a qualified person, as such term is defined in NI 43-101, has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and the Company is not treating the historical estimate as current mineral resources or mineral reserves.


Ongoing Exploration

Trenching is currently being carried out at Tipispan and El Rastro and soil sampling will be expanded to other prospective areas. Alder is following up on rock chip sampling that has returned up to 114.12 g/t Au at El Rastro, 12.33 g/t Au at Tipispan as well as seven other samples that returned values between 1.05 g/t Au and 6.90 g/t Au, mainly in the Bambana area.


Quality Assurance/Quality Control

Continuous horizontal chip samples are collected 0.2 metres above the trench floor from cleaned surfaces, collected into heavy gauge plastic bags, sealed on-site, then stored at Alder's Rosita field office until they can be transported by company or laboratory personnel to Inspectorate Exploration and Mining Services' sample preparation facility in Managua. There, pulps are prepared for shipping to Inspectorate's Analytical laboratory in Vancouver, where each sample is analyzed via 1 assay-tonne fire assay for gold and 30 element ICP (Inductively Coupled Plasma-atomic emission spectrometry) methods for copper, silver and 28 other elements. Alder has implemented an industry standard Quality Assurance/Quality Control program that includes the insertion of blanks into the sample stream.

In August 2011, Alder entered into an option agreement to acquire a 65% interest in the Rosita D concession from Calibre Mining Corp. by issuing 1,000,000 shares and incurring expenditures of $4,000,000 over four years, of which $500,000 must be spent by October 2012. Alder has completed this $500,000 expenditure commitment, and is more than half way to meeting its $4,000,000 earn-in obligation.
