HIGHLIGHTS:
- New drill targets defined on an extension of the
Shumagin Zone (now calledSH-1 Zone ) and atBloomer Ridge and theAquila Zone on the Shumagin Trend.- Mapping program made new surface gold discoveries of 104g/t, 27g/t, and 21g/t Au above unmined areas at the historic
Apollo Mine .-
Bloomer Ridge confirmed as a prospect with structural and geochemical similarities to SH-1 with surface samples up to 4.7g/t Au.- Results add to understanding the structures that control gold distribution and which will guide future exploration at the
Unga Project .- Redstar is working towards completing a maiden 43-101 Resource on
SH-1 Zone in Q1.

The key findings of this work are as follows:
a)
The SH-1 Zone (formerly theShumagin Zone ):An interpretation of surface linear features shows that high grade gold bearing structures on the Shumagin Trend are located tangentially to dacitic intrusives. This is analogous to some gold deposits in the Refugio mining district inChile . One of these linears indicates that the western extension of theSH-1 Zone is a southwest striking splay that extends toward Pray's Vein. Surface samples taken by Redstar at Pray's Vein have returned up to 11.8g/t Au, and a historic drill hole byBattle Mountain Gold in the late 1980s returned an assay of 2.4m grading 0.18g/t Au + 6.9g/t Ag when the hole was abandoned at -45m down-hole. In the diagram (Fig 1),pink polygons are high prospectivity drill targets and irregular circulars are suspected dacite intrusives. This interpretation suggests that the mapped structure between theSH-1 Zone and Pray's Vein may be the western extension of theSH-1 Zone and is a high priority drill target.
b)Apollo-Sitka Trend:The mapping shows that historic mining at Apollo-
Sitka was focused on dilational structures resulting from rotation of the strike direction within a shear duplex. This exercise revealed a new dilational structure in the immediate area of the historic Apollo mine. Furthermore, surface sampling returned assays including 104g/t Au located immediately above previously mapped mine workings where significant amounts of sulfide-hosted gold and base metal mineralization was abandoned at the turn of the 19thcentury as untreatable in the original stamp-mills. The underground workings, mapped andsampled byAlaska Apollo Mining in the 1990s, followed a vein for 500m of strike and returned underground assays up to 6m grading 8g/t Au with Ag+Pb+Zn credits (Fig 2). The presence of a near mine, untested dilational structure as well as high grade samples at surface with historically recorded mineralization underneath has yielded twohigh probability drill targets.

c)
Bloomer Ridge :Bloomer Ridge is located 800m south of, parallel toand 200m topographically higher thanthe high-gradeSH-1 Zone .Ubiquitous millimetric scale, iron oxide bearing, quartz-carbonate veining has been mapped which contains up to 4.7g/t Au from surface sampling (Redstar 2019) along 1.4km of strike (Fig 3). The close proximity to and similarity in style of mineralization to that of theSH-1 Zone indicates theBloomer Ridge gold may be from the same source. Further, as the Ridge is higher than theSH-1 Zone , the underlying mineralization may be better preserved than that of the SH-1 zone which means thatBloomer Ridge is a high priority target for further mapping and eventual drilling.

d)Aquila: Sampling and drilling by Battle Mountain in the 1980s returned assays up to 30g/t Au at surface and assays from drill results that included 0.46m grading 103g/t Au in DDH AQAME02which was abandoned at -48m down-hole. 2019 mapping showstwo zones within a shear duplex occurring tangentially to and within 400m of a centrally located dacitic intrusive (Fig 4). The dilational nature of the structures at Aquila supported by high grade assays from previous drilling means that the
Aquila Zone is a high probability target for further drilling.
