Timberline to Off-set Drill Core Intercept at Elder Creek Porphyry Cu-Mo-Au-Ag Project, Nevada
Coeur d’Alene, Idaho – March 27 2019 – Timberline Resources Corporation (OTCQB: TLRS; TSX-V: TBR) (“Timberline” or the “Company”) today announced Phase 2 drilling plans at the Elder Creek Project in Nevada’s Battle Mountain mining district. Approximately 2,000 m of drilling are planned in up to four holes to test a strong IP/resistivity (IP) anomaly identified in December, 2018. Two holes drilled by the Company earlier in 2018, located on the periphery of the anomaly, contain significant copper mineralization (see Table 1 and Figures 1, 2, 3, 5 and 6), while shallow historical holes drilled for gold (Figure 3) intercepted material amounts of copper:

The proposed holes (Figures 1 through 6) will test a strong IP anomaly (see press release dated January 8, 2019 at http://timberlineresources.co/press-releases/) identified by the survey which was completed by Zonge Geophysics. Multiple additional targets have been defined through integrated interpretation of surface and drill-hole geology, re-processed magnetic and gravity data, and the IP survey results. These targets represent follow-up discovery opportunities which are fully permitted and drill-ready.
The IP anomaly delineates a concentration of sulfide minerals in a body of rock extending ≥ 1,600 m long and approximately 500 – 800 m wide (Figures 1 and 2). The anomaly follows two parallel faults along a N/NE trend, and further north, also follows a NW’ly trend. It occurs within a very large (2 x 4 km) oval-shaped copper-molybdenum-gold-silver system defined by hydrothermal alteration and metal zoning characteristic of porphyry copper deposits.
Steven Osterberg, Timberline’s President and CEO commented, “We consider Elder Creek to be a rare opportunity to discover a very large polymetallic porphyry system in Nevada, one of the world’s premier mining jurisdictions. The target is particularly compelling being located within the metallogenically well-endowed copper and gold-producing Battle Mountain mining district where immediately infrastructure is excellent. Phase 2 drilling will begin in Q2 and will test the heart of the IP anomaly.”

The initial two proposed holes will test the strong IP anomaly, with locations of the remaining holes contingent upon results.
Proposed drill hole 1 (PDH-1) (Figures 1-3) will offset core hole CCEC18-02 and target coincident IP, magnetic (Figure 5), and gravity (Figure 6) anomalies in the area where chargeability is strongest, which likely represents the greatest sulfide mineral concentration.
Proposed Drill Hole 2 (PDH-2) will test the core of the IP anomaly N/NE of PDH-1 where coincident anomalies also indicate relatively dense, magnetic rocks (Figures 4 – 6).
The Company expects to resume drilling in Q2/2019. Drill sites are fully permitted with the US Bureau of Land Management (BLM).

Elder Creek Property
Timberline’s Elder Creek and adjacent Paiute copper-gold properties lie within the prolific Battle Mountain District of Nevada, approximately 11 miles (18 km) north of Newmont’s Phoenix mining complex. Data compiled from over 40-plus years of exploration on the property documents only shallow, historic drilling within a pronounced magnetic low considered to be the core of a large porphyry copper-gold hydrothermal system. Furthermore, only shallow drilling occurred along the north and northeastern magnetic high and primarily targeted gold. Geologic and geophysical characteristics, and rock geochemical sampling results evident at Elder Creek (see press release dated June 18, 2018 at http://timberlineresources.co/press-releases/) are common to major porphyry copper deposits.

About Timberline Resources
Timberline Resources Corporation is focused on advancing district-scale gold exploration and development projects in Nevada. These include its 23 square-mile Eureka property, comprising the Lookout Mountain, Windfall, and Oswego projects which lie along three separate structural stratigraphic trends defined by distinct geochemical gold anomalies, as well as being operator of both the Paiute joint venture project with a subsidiary of Barrick Gold, and the Elder Creek joint venture with McEwen Mining. All of these properties lie on the prolific Battle Mountain-Eureka gold trend. Timberline also owns the Seven Troughs property in Northern Nevada, which is one of the state’s highest-grade former gold producers. Timberline has increased its owned and controlled mineral rights in Nevada to over 43 square miles (27,500 acres).
