Timberline Extends Gold Zone at Lookout Mountain With Additional Drill Results from South Eureka, Nevada
COEUR D'ALENE, IDAHO -- (Marketwire) -- 01/17/12 -- Timberline Resources Corporation (TSX VENTURE: TBR)(NYSE Amex: TLR) ('Timberline' or the 'Company') today announced that it has extended the gold zone at its Lookout Mountain Project with additional significant assay results from the recently-completed 45,000-foot drill program at its South Eureka Property near Eureka, Nevada.
Highlights reported today include several significant intercepts with excellent recoveries of oxide gold mineralization. Hole BHSE-108 returned three mineralized intervals, including 0.016 ounces per ton (opt) gold (0.55 grams per tonne (g/t)) over 240 feet (73.2 metres), and Hole BHSE-124 returned 0.022 opt gold (0.75 g/t) over 75 feet (22.9 metres). At South Adit, highlights included Hole BHSE-121 which returned 0.021 opt gold (0.72 g/t) over 80 feet (24.4 metres) and 0.016 opt gold (0.55 g/t) over 45 feet (13.7 metres). Infill and step-out drilling at South Adit in 2011 successfully confirmed and expanded the historic gold resource. Additional drilling in the 2012 program will seek to expand this zone.
These and other results from the 2011 drill program have successfully extended the gold zone at Lookout Mountain 600 feet to the south of the existing resource, and have expanded gold mineralization along the west margin of the resource. Results from Lookout Mountain, and from the South Adit area, are expected to significantly increase the current Lookout Mountain NI 43-101 Measured and Indicated resource estimate(1) of 286,000 ounces of gold, and the Inferred resource estimate(1) of 206,000 ounces of gold.
Paul Dircksen, Timberline's President and CEO said, 'We continue to be very pleased with drill results from our South Eureka property. Progress achieved in 2011 includes the demonstration of mineralization continuity to the south and west of Lookout Mountain, consistent gold grades and metallurgical characteristics, and improved definition of structural controls and possible pit boundaries. Our 2011 drill program has succeeded in advancing the project toward development of a low cost, run-of-mine heap leach gold operation. We also enjoyed drilling success in the South Adit area and will define a NI 43-101 resource in that zone for the first time.'

The significance of the current drilling results at Lookout Mountain include:
-- Mineralization reported in BHSE-105 and BHSE-106 when combined with the
results from BHSE-082 returned significant thicknesses of gold
mineralization demonstrating gold continuity approximately 700 feet west
of gold zones previously reported in holes BHSE-102 through BHSE-104,
and south of the previous resource estimate.
-- The gold interval encountered in BHSE-124 establishes continuity of
mineralization between holes BHSE-096 and BHSE-099 along a NNE structure
extending approximately 600 feet south of the previous resource
estimate.
-- Gold intervals in BHSE-108 add positive definition to the west margins
of mineralization and to gold controls along a NE structure.
-- Drill holes BHSE-097 and BHSE-119 demonstrate that the gold bearing
structure continues and is open for resource expansion to the south and
east toward the South Adit zone.
-- Drill Hole BHSE-115, when combined with holes BHSE-079 and BHSE-080,
extends mineralization to the west of the existing Lookout Mountain pit
and will add to the resource while reducing the potential waste to ore
ratio.
Paul Dircksen, Timberline's Executive Chairman, is a Qualified Person as defined by National Instrument 43-101 and has reviewed and approved the technical contents of this release. He has verified the drill results and other data disclosed in this news release, including sampling, analytical and test data. Field work has been conducted under his supervision. The Timberline sampling and analysis program included an industry standard QA/QC program, including the insertion of certified standards and blank material into the assay stream. After logging and cutting or dividing the sample intervals in half, the samples were picked up by Inspectorate America Corporation and taken to their ISO-9001 certified assay lab in Sparks, Nevada for analysis. The samples were analyzed for gold using a standard 30g fire assay with an AA finish. Samples returning a gold value in excess of 3 ppm were re-analyzed using a 30g fire assay with a gravimetric finish. ALS Chemex, an ISO-9001 certified assay lab, provides check assays for mineralized intervals with gold assays above 100 ppb gold.
