Alder trenching returns exceptional results at Rosita Project, Northeast Nicaragua

Thursday, Jan 10, 2013

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.
