(“GoldInxs,” or the “Company”) (TSXV: INXS) is pleased to announce the successful completion of a helicopter-supported field program at the Company’s Millar Project, a 345-hectare exploration property located within British Columbia’s world-renowned Golden Triangle, located Northwest of Contango Silver &amp; Gold’s Kitsault Valley Project (the Dolly Varden Trend). The August exploration program focused on the “White Linears” area of the Millar property (Figure 1), where the field team completed geological mapping, prospecting, structural observations and rock sampling. The program identified multiple areas of quartz veining, shearing, brecciation, alteration, and gossanous oxidized units along with other visible mineralization indicators, further supporting the Company’s exploration thesis at Millar. Successful Work Program Identifies Multiple Areas of Quartz Veining, Alteration and Mineralization The completed field program documented a range of geological features including: <ul type="disc"><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">Sheared volcanic quartz veining, with structural measurements recorded during mapping;</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">A quartz vein approximately 1.5 metres wide, with an observed strike of approximately 110° steeply dipping;</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">A quartz-intrusive vein approximately 12 inches wide and traceable for over 30 metres;</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">Identified several smaller quartz veins and veinlets associated with areas of oxidation staining;</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">Observed chloritized vein margins and host rock alteration, including qtz/calcite-bearing veining;</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">Gossanous material in situ, including gossanous volcanics associated with mineralization;</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">Examined recently exposed rusty, oxidized and altered volcanic and gabbroic rock outcrops; and</li><li style="margin-top:5pt; margin-bottom:5pt; text-align:justify;">Confirmed several linear geological features within the “White Linears” area. </li></ul> Several representative rock and float samples were collected from the various observed geological features for further analysis and assay. The field observations were consistent with several of the geological characteristics previously identified by GoldInxs at Millar, including the potential for both vein-hosted precious-metal and skarn-style mineralization. Against this backdrop, Millar exhibits several of the geological characteristics that warrant systematic follow-up, including further methodical prospecting of the Hazelton Group volcanic rocks, widespread quartz veining, hydrothermal alteration, gossanous material and anomalous Au-Ag-Cu-Pb-Zn mineralization. The recent fieldwork has confirmed the presence of multiple quartz-vein, shearing, brecciation and alteration features in the “White Linears” area, with assays pending (Figure 1). <img alt="Figure 1: Millar Property – White Linears Area" height="295.02px" name="GNW_RichHtml_IMG" src="https://ml.globenewswire.com/Resource/Download/a74cd530-5a3e-469c-8879-1c2297e28312/image2.png" width="663.05px" data-dpi="144" data-caption="Millar Property – White Linears Area" data-filename="image2.png" /> Figure 1: Millar Property – White Linears Area <img alt="Figure 2: Millar Property - Brecciated Volcanic Quartz Vein" height="366.26px" name="GNW_RichHtml_IMG" src="https://ml.globenewswire.com/Resource/Download/0c6cc4b4-4003-4901-abe8-39dcc5052205/image3.png" width="486.53px" data-dpi="144" data-caption="Millar Property - Brecciated Volcanic Quartz Vein" data-filename="image3.png" /> Figure 2: Millar Property - Brecciated Volcanic Quartz Vein Jurisdiction: Positioned Along a Highly Prospective Golden Triangle Mineral Trend Millar sits within a broader structural and metallogenic corridor within the Golden Triangle and is positioned northwest of the Kitsault Valley Project, a region characterized by significant historical mineral production and numerous precious and base-metal deposits (Figure 5). The Company is applying systematic modern exploration techniques to the under-explored property with the objective of defining a more robust geological model and identifying high-priority targets for follow-up exploration. The surrounding region has a long history of high-grade production, including more than 20 million ounces of historical silver production from the Dolly Varden and Torbrit mines, more than 3.3 million ounces of gold and 160 million ounces of silver from Eskay Creek, and significant historical gold and silver production from the Premier/Silbak Premier district. The proximity of the Millar project to other deposits does not mean similar mineralization or resources will be found on the property. GoldInxs’ existing interpretation of Millar identifies extensive quartz veining, iron-oxide alteration and anomalous gold, silver, copper, lead and zinc associated with sulphide-bearing quartz veins, supporting the potential for multiple mineralization styles, including vein-hosted precious-metal and skarn-style systems.  The recently completed field program provides additional surface information to build a more detailed geological understanding of the Millar property through defining the distribution, orientation and structural controls of quartz veining and alteration. GoldInxs will integrate the new geological observations, structural data and assay results with existing exploration data to further refine priority targets. Analytical results from the field program have not yet been received and no conclusions regarding grades or economic mineralization can be drawn at this time, there can be no assurance that the samples collected will return economically significant grades or support the identification of a mineral resource. <img alt="Figure 3: Millar Property - Quartz Contact Mineralization" height="388.9px" name="GNW_RichHtml_IMG" src="https://ml.globenewswire.com/Resource/Download/180e2354-31cc-446a-8092-06b1ddf24afb/image4.png" width="516.59px" data-dpi="144" data-caption="Millar Property - Quartz Contact Mineralization" data-filename="image4.png" /> Figure 3: Millar Property - Quartz Contact Mineralization <img alt="Figure 4: Millar Property - Northern edge of the main diorite / intrusive body" height="411.73px" name="GNW_RichHtml_IMG" src="https://ml.globenewswire.com/Resource/Download/aa735929-fd8c-4903-9f55-9aed51150fe6/image5.png" width="552.08px" data-dpi="144" data-caption="Millar Property - Northern edge of the main diorite / intrusive body" data-filename="image5.png" /> Figure 4: Millar Property - Northern edge of the main diorite / intrusive body <img alt="Figure 5: Millar Property – Regional Positioning in Golden Triangle" height="350.64px" name="GNW_RichHtml_IMG" src="https://ml.globenewswire.com/Resource/Download/2f0992cb-5f4f-4d19-8c8e-5be16d75bd13/image6.png" width="623.05px" data-dpi="72" data-caption="Millar Property – Regional Positioning in Golden Triangle" data-filename="image6.png" /> Figure 5: Millar Property – Regional Positioning in Golden Triangle Qualified Person The technical information in this news release has been reviewed and approved by Darcy Vis, P.Geo., Vice President of Exploration of GoldInxs Mining Corp., and President of Tripoint Geological Services Ltd., who is a Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
