Franconia Minerals Summarizes Results Following Drilling & Bulk Sample Collection at its Birch Lake Copper-Nickel-PGM Project | ||
SPOKANE, WASHINGTON--(Marketwire - Feb. 9, 2009) - Franconia Minerals Corporation ("Franconia" or the "Company") (TSX:FRA) is pleased to present a summary of the results of its completed 2008 barge drilling program at the Birch Lake deposit in northern Minnesota. A total of nine holes and associated wedged offsets for 19,566 feet were drilled between May and late September 2008. Results for all holes are presented here (see Table 1 and map). The drilling mainly tested the northwestern sector of the Birch Lake deposit for extension of the previously outlined resource. Every hole encountered good thicknesses of mineralization and the drilling shows that the deposit continues in this northwesterly direction and remains open for further expansion. This latest drilling represents the latest phase of a comprehensive program initiated in June 2006. The results of the 2008 program will enable the Company to update its resource estimates for the deposit with the expectation of converting much of the current Inferred Resource to the Indicated category and adding additional, new Inferred Resources. The program also provided representative material for bulk metallurgical testing. All holes and wedged offsets were drilled using wide diameter (PQ) core. Wedges were drilled on the first two holes of the 2008 program. The wedged offsets provide additional material for metallurgical tests but only provide sampling for a very limited distance away from the original drill hole. Wedging was discontinued for the remainder of the holes as a large enough sample for bulk testing (approximately 60 tonnes) had been collected. Now that sufficient metallurgical sample is in hand, it is likely that the majority of future drilling at Birch Lake will utilize smaller diameter, more economical NQ core drilling. Following the planned resource estimate update, a Preliminary Economic Assessment would examine the viability of a 20,000 tonnes-per-day, 20 year-plus mine-life Birch Lake underground operation. This assessment is expected to be followed by a more comprehensive and detailed pre-feasibility study. Table 1

(1) CIM definitions were followed for Mineral Resource estimation and
classification.
(2) Mineral Resources are estimated for the Main Zone of the deposit as
defined and wireframed based on mineral occurrence, grades, Cu:Pd,
Ni:Pt ratios and other lithologic and stratigraphic factors.
(3) Mineral Resources were estimated using average long-term metal US$
prices of $8.50/lb nickel, $2.50/lb copper, $20/lb Co, $1,200/oz
platinum, $350/oz palladium and $800/oz gold.
(4) Copper equivalent (CuEq%) equals Cu% + 2.47 x Ni% + 2.78 x Co% + 0.19
x Au g/t + 0.59 x Pt g/t + 0.16 x Pd g/t based on metal prices and
expected process recovery.
(5) TPM is Au g/t + Pt g/t + Pd g/t.
(6) Bulk density is 3.07 t/m(3) as averaged from specific gravity testing.
(7) Co, Au, Pt, Pd grades, that are lacking in historic drill holes, have
been entered in the resource database based on regression of assay
grades from Franconia drill hole assays.
(8) Resources are estimated from approximately 345 m depth to approximately
840 m depth.
(9) Scott Wilson RPA recommends reporting resources for the wireframed zone.
Core samples were prepared at the ALS Chemex Ltd. Laboratories in Thunder Bay and then shipped to its analytical facilities in Vancouver. Samples were analyzed for gold, platinum and palladium using a standard fire assay with an ICP finish, as well as for 34 base metals and trace elements using a four-acid (near-total) digestion and a combination of ICPMS and ICPAES. ICP over-limits were reanalyzed using sodium peroxide fusion and acid dissolution followed by ICPAES. All technical data have been reviewed by Brian Gavin, Franconia's president and CEO, who is also an appropriately qualified person as defined by NI 43-101. Franconia Minerals Corporation trades on the TSX under the symbol FRA. (For additional information see www.franconiaminerals.com.) Franconia currently has 59,082,572 shares issued and outstanding. FORWARD-LOOKING STATEMENT: Although Franconia Minerals Corporation believes many of its properties have promising potential, these properties are in the early stages of exploration. None have yet been shown to contain proven or probable mineral reserves. There can be no assurance that such reserves will be identified on any property, or that, if identified, any mineralization may be economically extracted.
