Timberline Resources Drilling Confirms Porphyry Hosted Gold Discovery on the Paiute Project, Battle Mountain District, Nevada

Highlights:

PCRC 19-01 intercepted 125 feet (ft) (38 meters (m)) grading 0.36 g/t Au with associated pyrrhotite-pyrite-arsenopyrite in silicified, metamorphosed arkosic sandstone.

PCRC 19-02 intercepted multiple zones of gold mineralization in granodiorite porphyry and metamorphosed arkosic sandstone, including 40 ft (12 m) of 0.61 g/t , 80 ft (24 m) of 0.51, 25 ft (8 m) of 1.12 g/t, and 25 ft (8 m) of 0.48 g/t over its 710 feet (216 m) length and bottomed in mineralization.

Timberline's President and CEO, Steve Osterberg commented, "Our initial drilling at Paiute confirms the presence of a large, near-surface gold system. The target zones remain largely untested by drilling, and historical drilling (Table 2) intercepted significant gold at shallow (<500 ft; 150 m) depths, with several holes ending in gold mineralization."

EXPLORATION TARGETS

Gold-Silver Structural Zone Target: PCRC 19-01 bottomed in 160 ft (49 m) of silicified granodiorite porphyry with geochemical characteristics similar to that of PCRC19-02. The previously identified 2 km-long gold "Lone Tree-type" structural zone remains largely untested. The structural zone includes surface rock chip samples (see Figure 1 and Table 3) which previously returned multiple values greater than 1.0 gram per tonne ("g/t") of gold including two samples over 10 g/t gold and one sample with 42.9 g/t gold and 527 g/t silver (Table 3) (see press release dated May 24, 2018 @ http://timberlineresources.co/press-releases).

Gold Porphyry Target: PCRC 19-02 twinned and deepened historical hole ICBM-95-06, which intercepted porphyry-style gold mineralization in highly silica-altered, sulfide-poor (trace - 1% pyrite) granodiorite porphyry, and remains opened to depth The mineralization in PCRC 19-02 expands on multiple intercepts in nearby historic holes (Figure 2 and Table 2).

EXPLORATION PLANS:

The Paiute project has the potential for bulk-mineable, open-pit gold mineralization based on the thicknesses and grades drilled to date. The Company is acquiring historical IP/Resistivity, and magnetic survey data to guide future drilling of the largely untested structural zone and porphyry targets.

Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance: Samples of reverse circulation cuttings were collected at the drill rig at 5 feet intervals under the supervision of a Company representative and transported to ALS in Nevada for analyses. Samples were assayed for gold by Fire Assay of a 30 gram (1 assay ton) charge with an AA finish (ALS code Au-AA23). Samples were also assayed for a 48 multi-element using four acid ICP-MS (code ME-MS61).

About Timberline Resources: Timberline Resources Corp. is focused on advancing district-scale gold exploration and development projects in Nevada. These include the Lookout Mountain joint venture project with PM & Gold Mines operated by Timberline and the Windfall project, both in the Eureka district, as well as being operator of both the Paiute joint venture project with Nevada Gold Mines, and the Elder Creek joint venture with McEwen Mining, both in the Battle Mountain district. 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 producers. Timberline has increased its owned and controlled mineral rights in Nevada to over 43 square miles (27,500 acres). Detailed maps and NI 43-101 estimated resource information for the Eureka property may be viewed at http://timberlineresources.co/.
