1Reported grades were calculated using a 0.2 g/t cut-off grade for primary intervals and a 2 g/t cut-off grade for included intervals. Intervals correspond to downhole thickness, with insufficient information available to calculate true thickness.
Caleb Stroup, Headwater’s President and CEO, states: “We are very impressed with the widespread and consistent nature of anomalous gold mineralization beginning at approximately 100 metres below surface at Spring Peak; depths which were not tested by shallow historic drilling. In particular, the grades and widths encountered in SP21-03 represent a new blind gold discovery in a prolific historic district2, with compelling follow-up targets immediately down dip. Although limited in scale, the first-pass drilling has clearly accomplished our primary goal of demonstrating the existence of significant blind gold mineralization below a barren alteration cap. We very much look forward to future drilling on the Project and are excited to test the size and grade potential of this new discovery.

About the Spring Peak 2021 Drill Program:
The Spring Peak Project is located in the Aurora Mining District of west-central Nevada, approximately 50 kilometres southwest of the town of Hawthorne and adjoins Hecla Mining’s Aurora mine complex. A large hydrothermal alteration cell occurs in the center of the Spring Peak Project area which is interpreted by Headwater geologists as representing the high-level manifestations of an epithermal precious metal system. Using a variety of geological and geophysical targeting tools, Headwater geologists identified several previously undrilled high-grade vein targets at depth beneath this high-level alteration cap, which were tested by the recent drilling.
Headwater’s initial first-pass RC drilling program consisted of five drill holes totalling 1,350 metres. Drilling successfully intersected epithermal quartz veins at a range of elevations in multiple structures. Individual vein zones range from 1.4 to 18.3 metres in drilled width. The widest zone of veining and mineralization occurred in hole SP21-03 which intersected a fault-hosted vein zone immediately beneath a mapped silica sinter at surface. This interval returned gold values of 1.00 g/t gold over 38.1 metres, including 9.2 metres of 2.49 g/t gold, representing a new, blind gold discovery and a confirmation of the Headwater exploration model. Drill hole SP21-03 was terminated due to challenging drilling conditions while still in alteration, and only 6.1 metres beyond the reported 1.00 g/t interval. The vein textures encountered in SP21-03 range from clean, white chalcedonic quartz to finely banded chalcedonic quartz with quartz-after-platy-calcite textures, and minor stringers and clots of dark grey sulfosalts. These textures, together with the relatively low Ag:Au ratio (approximately 10:1), and the absence of appreciable base metal values, suggest SP21-03 only penetrated the very upper parts of the targeted boiling zone, with the primary high-grade target remaining at depth and yet to be drill tested. The mineralization encountered in SP21-03 is open in all directions. The nearest drill hole which penetrated to the appropriate depth is SP21-02, approximately 900 metres to the west, which ended in 16.8 m grading 0.28 g/t Au.

Drill holes SP21-02, SP21-04, and SP21-05 also intercepted significant intervals of gold mineralization in stockwork quartz vein zones beginning approximately 100 metres below the modern surface; depths which were previously not tested by historic drilling. Drill hole SP21-01 returned no significant gold intercepts. In aggregate, these results demonstrate the presence of a significant >1 kilometre zone of highly-anomalous gold values in the upper portions of a widespread epithermal boiling horizon. Headwater geologists believe this to be highly encouraging, especially given the proximity and geologic similarity with the mineralization in the nearby high-grade Aurora mine area2, approximately three kilometres to the northwest.
Phase II Follow-up:
The Company believes that RC drilling was an efficient and cost-effective means to confirm the presence of a viable epithermal precious metal system at depth, but has inherent limitations in the depth extent to which it is practical. Future programs will include a combination of RC drilling and diamond core to better test the true width and grade of the veins encountered and better ensure target depths can be reached. Future core drilling will also implement oriented core technologies, allowing the collection of detailed structural information critical for projecting and offsetting vein intercepts. Headwater geologists are currently updating the exploration model at Spring Peak by incorporating all new information and expanding the geologic mapping and surface geochemical sampling. The extensive CSAMT resistivity geophysical data collected by previous operators on the property appears to be an excellent tool for delineating zones of silicification and veining at depth, and additional resistivity modelling efforts are being initiated to help the targeting process.

The Company is in the process of planning a drill program to offset the newly discovered gold mineralization at depth and test additional portions of the strike extent of the system. Diamond core follow-up holes will be designed to offset the vein zone encountered in SP21-03 at depth, as well as other structural zones in a favorable geologic setting for the formation of high-grade veins (Figure 3).

The Agreement allows for Headwater to acquire a 100% undivided interest, subject to retained royalties, in the Spring Peak project from Orogen Royalties Inc. by incurring exploration expenditures of US$250,000 prior to July 2023, making a cash or share payment totaling US$250,000 (subject to receipt of certain future permitting milestones) and maintaining all required underlying option payments and royalties as outlined below.
Orogen will retain a 0.5% net smelter return royalty and an option to purchase an additional 0.5% NSR royalty for US$1,000,000. The underlying option payments include an annual lease payment commencing at US$40,000 and escalating up to US$60,000 (indexed to inflation) with a US$500,000 buyout. The underlying optionor will retain a 2.5% NSR royalty of which 1.5% of the NSR may be purchased for US$1,500,000 at any time.
Sample Quality Control:
Drilling at Spring Peak was conducted by Boart Longyear using a wheel-mounted reverse circulation drill rig. The drill chips were logged on site and at Company offices in Reno, Nevada. Samples were transported from site to American Assay Laboratories (“AAL”), located in Sparks, Nevada by American Assay personnel. Prior to dispatch, samples were placed in numbered bags with regular insertion of blind internationally certified reference materials, blanks, or a sample duplicate. American Assay Laboratories are an accredited analytical laboratory meeting ISO/IEC 17025:2017 and AC89 IAS requirements. Samples were prepared by standard AAL crushing and grinding methods. The pulps were then assayed for 21 elements via AAL method ICP-2AM21 using a 0.5 g sample after a two acid near total digest with an ICP-OES/MS finish. Gold was assayed by fire assay using AAL method FA-Pb30 using a 30g sample charge and ICP-OES finish. Laboratory standards and QA-QC are monitored by the Company.
