Timberline Resources : Drills More Oxide and High-Grade Gold at Eureka Project, Nevada; Appoints New Director

Geological and Drilling Details

All of these holes encountered mineralization hosted in the Dunderberg Shale, commonly near its basal contact with the Hamburg Dolomite, which is heavily disrupted by faulting and brecciation. These rocks are part of the Cambrian-aged section, which hosts mineralization both at the Lookout Mountain Deposit and at the historic Windfall Mine, several kilometers to the northeast within the Eureka Project. Timberline geologists noted extensive alteration in the RC cuttings, including intense decalcification with variable amounts of silicification.

The deeper sulfide mineralization reported in drill hole BHSE-187 occurs in downfaulted Dunderberg Shale that is carbonaceous and sulfidic, with orpiment (arsenic sulfide mineral). This higher-grade intercept is a significant step-out of approximately 75 meters to the northeast from the Lookout Mountain resource. It is correlative with the Water Well or Orpiment Discovery Zone, and extends that zone to the north from historical intercepts, which include: 4.6m at 4.73 g/t Au and 7.7m at 5.02 g/t Au (see Company news release dated April 20, 2015: 'Timberline Completes Successful Eureka Drill Program').

Assay results are pending for three core holes which are significant step-outs from the existing mineral resource area. See Figure 1 for the location of the 2020 RC and core holes relative to the existing resource and the Lookout Mountain open pit.

Corporate Update

Timberline is also pleased to announce the appointment of Mr. Patrick Highsmith, its President and CEO, to the Board of Directors effective January 1, 2021.

In addition, the Company announces that it has submitted a Notification of Late Filing of Form 10-K with the United States Securities and Exchange Commission for the fiscal year ended on September 30, 2020. The SEC has approved the extension of filing of the Company's annual report by two weeks.

Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance

Collection of reverse circulation percussion drill samples and diamond drill core was completed under the supervision of a Company representative. Personnel from Timberline or the drilling contractors transport the RC and core samples to Timberline's secure Eureka facility where samples are logged and prepared for transport to the lab. Senior geologists direct the cutting and sampling of the core and selection of representative samples for assay. Quality control is monitored by the insertion of numerous blind certified standard reference materials, field duplicates, and blanks into each sample shipment. Company representatives complete sample dispatch paperwork and deliver the samples to ALS USA Inc. (ALS) in Elko, Nevada for sample preparation. Drill samples are assayed by ALS in Reno, Nevada for gold by fire assay of a 30-gram charge with an AA or ICP-ES finish (ALS code Au-AA23). The overlimits for gold samples assaying above 10 g/t are determined by a 30-gram fire assay with gravimetric finish. In addition, highly mineralized samples (>0.2 g/t Au) are submitted for multi-element analysis (33 elements) by four-acid digestion and ICP-ES determination (code ME-ICP61).

According to Timberline instruction, samples assaying above 0.2 g/t gold are also tested for cyanide-soluble gold with the 30-gram Au-AA13 method. This form of analysis is a preliminary indication of the favorability of the sample for gold recovery by cyanide leach. Since the test is performed on a small aliquot of a pulverized sample, it is not a reliable indication of metallurgical recovery.
