Revised - Alder Targets 1.75 to 2.25 Million Tonnes of Tailings
Grading from 0.14-0.30% Cu, 0.52-0.57 g/t Au and 6.37-12.55 g/t Ag
TORONTO, ONTARIO--(Marketwired - Jan 20, 2014) - Alder Resources
Ltd.'s ("Alder" or the "Company") (TSX-VENTURE:ALR) news release is
being revised to include required cautionary statements. Alder's
work over the past few months has targeted a tailings tonnage of
between 1.75 and 2.25 million tonnes grading from 0.14 to 0.30% Cu,
0.52 to 0.57 g/t Au and 6.37 to 12.55 g/t Ag (see figure and
table). The target target is the result of 99, up to 6 metre deep,
augur holes, with most holes penetrating to the base of the
tailings. The average grade of these intercepts is 0.21% Cu, 0.55
g/t Au and 9.37 g/t Ag over an average width of 5.4 metres. Within
this block, Alder is targeting a higher grade sub-block containing
between 400,000 to 500,000 tonnes grading from 0.38 to 0.41 % Cu,
0.70 to 1.00 g/t Au and 6.37 to 10.65 g/t Ag.

In addition to the area that Alder sampled in detail, 66
additional auger holes, spaced approximately 100 metres apart (see
figure), covering an area of 0.45 hectares, and having an average
thickness of 2.76 metres, returned average grades of 0.16% Cu, 0.21
g/t Au and 5.56 g/t Ag. Sampling completed to date does not
encompass the entire tailings area.
Metallurgical work is still required to determine how much of
the metal in the tailings can be recovered and if the recovery
methods are economically feasible.
The potential quantity and grade of the tailings material is
conceptual in nature, there has been insufficient exploration to
define a mineral resource in respect of the tailings and it is
uncertain if further exploration will result in the target being
delineated as a mineral resource.
Don Dudek, President and CEO, is quoted: "The addition of a well
defined tailings target with compelling grades further supports
Alder's plan to complete the metallurgical studies required so that
a business case for the project can be developed. This project is
more advanced than most in that there is a large mineral resource
already stockpiled on surface."
Alder is currently reviewing financing alternatives to fund the
metallurgical and additional studies that are required, including
the sale of a royalty on the property.
In summary, the Rosita property is well endowed and Alder
management strongly believe that the existing stockpile resource
and historic near surface mineral resources are sufficient to
justify defining the metallurgical characteristics of the
stockpiles. In addition, there are numerous exploration targets
that could add significant value to the project. The results of
metallurgical studies of the stockpiles are expected to define a
probable processing path, likely processing costs and which
exploration targets to prioritize. Assuming a cost effective
process for extracting the metals is defined, a preliminary
economic assessment would be the subsequent step.
Quality Assurance/Quality Control
Auger tailings samples were collected into heavy gauge plastic
bags, sealed on-site, then stored at Alder's Rosita field office
until transported by company or laboratory personnel to
Inspectorate Exploration and Mining Services' sample preparation
facility in Managua. In Managua, pulps were prepared for shipping
to Inspectorate's Analytical laboratory in Reno, Nevada, where each
sample was analyzed via one 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
certified standards and blanks into the sample stream. Standards
for the exploration program were prepared by WCM Minerals of
Burnaby, B.C. Based on the types of mineralization identified in
the region and the anticipated grades, four standards were selected
for the program, including CU157, CU159, CU164 and CU186. The
recommended Cu-Au-Ag-Mo values for the four geochemical standards
are shown in Table 4 below. Blanks were prepared from a felsic tuff
unit (the Quaternary Las Sierras Formation) which crops out at
Tipitapa, east of Managua. Apparently several other mining
companies have used this material in the past, and shown it to be
void of Au-Ag mineralization, although our own analyses indicate
that it frequently returns anomalous Cu values in the 100 to 300
ppm range. The QA/QC program was more rigorous for the tailings
sampling program consequently, only these results are discussed
below. In addition to Alder's QA/QC program, Inspectorate has
established an internal control system that includes the insertion
of standards every 30 samples; however, these have not been
evaluated.
Qualified Persons
The sampling program was carried out under the supervision of
Joe Arengi, M.Sc, P.Geo, Alder's past President and CEO and a
qualified person as defined by NI 43-101. Don Dudek, P. Geo.,
Alder's President and CEO and a qualified person as defined by NI
43-101, has reviewed and approved the scientific and technical
content of this news release.
About Alder Resources Ltd.
Alder is a resource company focused on the development of gold
and base metal projects throughout the Americas. Alder's current
high priority Cu-Au-Ag porphyry target is the Rosita project in
Nicaragua located 275 kilometres northeast of Managua. The company
has current Inferred mineral stock pile resources of 7.95 million
tonnes grading 0.62% Cu, 0.46 g/t Au and 9.21 g/t Ag with numerous
zones that have good near term potential to add to and enhance
these resources. See the technical report entitled "Rosita Cu-Au-Ag
Project, RAAN, Nicaragua, NI 43-101 Technical Report on Mineral
Resource Estimate of Rosita Stockpiles" effective as of May 8,
2012, which is available under the Company's profile at
www.sedar.com.
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. To date Alder has incurred
approximately $3.1 million of the $4.0 million obligation and has
until October 2015 to incur the remaining project expenditures. For
