GoldHaven Discovers Two Hydrothermal Alteration Zones by Initial Drilling at Alicia and Roma Gold Projects in the Maricunga District, northern Chile
October 6, 2021
Vancouver, British Columbia--(October 6, 2021) - GoldHaven Resources Corp. (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) ("GoldHaven" or the "Company") reports that initial drilling on the Alicia and Roma high sulphidation gold exploration projects in the Maricunga Gold District, north-central Chile has resulted in the discovery of two hydrothermal alteration zones.
Daniel Schieber, CEO of GoldHaven stated “The encouraging Phase I drill results at Alicia and Roma yielded two high priority targets. Thanks to our world-class technical team, the program came in under-budget and is a strong showcase of efficient exploration to potential strategic partners. We anticipate more significant results to come starting Q4 2021.”
The newly discovered alteration zones contain anomalous pathfinder elements and favourable alteration mineralogy identified using short wave infrared spectrometry (“SWIR”; see below). The SWIR survey results suggest that there may be potential for deeper gold and/or silver targets in these areas. These anomalies will be integrated into ongoing exploration targeting at the Alicia and Roma Gold projects.
Initial drill results suggest that GoldHaven has identified a large, highly prospective region of hydrothermal alteration including multiple targets which may contain epithermal gold mineralization. GoldHaven intends to conduct follow up exploration drilling on two targets identified in this round of drilling. Furthermore, at least 8 additional, large untested targets remain within the Alicia-Roma properties. In total, there are 12 targets identified by GoldHaven that occur within a Maricunga Belt scale regional NW-SE structural trend that includes Gold Fields’ Salares Norte deposit (5.2 million ounces gold equivalent2, currently under construction); which is located 30 to 35 km to the northwest.
Drill holes ALSAR-21-001 and RMSAR-21-002 contain compelling alteration mineralogy and pathfinder element responses that are interpreted to represent a distal epithermal gold environment. Additional exploration will be conducted with the objective to vector toward one or more potentially gold-mineralized zones. Due to the positive results obtained in holes ALSAR-21-001 and RMSAR-21-002 as well as the large number of untested anomalies remaining, a Phase II drill program is in preparation to begin between Q4 2021 and Q1 2022 and crews are being mobilized for pre-drilling studies to prioritize targets. This includes mapping and sampling of Phase I drill access roads, targeted backhoe trenching, sampling, spectrometry, extension of previous talus find sample lines as well as soil sample grid infill over the most significant anomalous zones. IP/Resistivity and CSAMT geophysics are also being considered. Follow up programs also remain to be initiated on the three remaining priority GoldHaven properties located within the Maricunga District, namely Jacqueline, Condor and Valle.
Phase I Exploration
A Phase I reconnaissance exploration program was conducted between March and April 2021 and included 5 reverse circulation holes (1,594 metres) designed to test 4 of a total of 12 priority targets defined by coincident surface geochemical gold and gold pathfinder anomalies associated with opaline and silica-alunite-kaolinite mineral assemblages hosted by dacitic-andesitic volcanic domes. The 12 targets initially delineated during project generation include 8 targets at Alicia and 4 at Roma. The targets range from a few hundred metres in diameter to a maximum of 2,500 metres long by 750 metres wide (Alicia Sur), with several covering more than 1 square kilometre in area. Note that of the four areas drilled three were tested with only one drillhole per target. As a comparison, the 1.5 Moz (17Mt@2,8 g/t) Puren deposit at La Coipa was a blind discovery made by drill hole #311.

Surface samples represented by coloured dots represent elevated values of pathfinder elements related to precious metals-high sulfidation deposits (As, Pb, Tl, Hg, Te, Se, Sb).
Exploration Drill Targeting Criteria:
- Surface grid-based geochemical soil anomaly.
- Favourable host rock consisting of dacitic-andesitic pyroclastic/tuffaceous sequences.
- Proximity to dome margins.
- Dominant brittle structural control within anomalies, the most evident being the northwest trend as well as possible structural intersections with northeast segmented structures, ring and concentric structures.
- The identification of preserved paleosurface (unconformity) and the favourable gold deposition elevation range or level of possible mineralization (e.g., approximately 4350m above sea level at Salares Norte and other mineralized systems in this portion of the Maricunga Gold Belt).
- Presence of high level, steam heated alteration, native sulfur, opaline silica.
An analysis of gold pathfinder or trace elements in soil samples along two main alteration trends revealed anomalies in As-Sb-Bi-Tl-In-Pb-Sn-Cd and Se-Te. The two main alteration trends include illite-muscovite and advanced argillic/steam heated alteration. These high-level alteration (steam-heated) zones are most intensely developed in holes ALSAR-21-001 and RMSAR-21-002 with the latter hole carrying partially oxidized pyrite.
Drill Hole Summaries
Hole ALSAR-21-001 returned anomalous montmorillonite/gypsum alteration in the upper part of the hole. This is interpreted to represent a high-level distal response to mineralization. Below this anomalous interval, the hole intersected dacite volcanic rocks interpreted to represent a volcanic dome. Since gold mineralization is often spatially associated with volcanic domes in epithermal settings follow up drilling will be considered. Anomalous thallium in this hole supports the presence of hydrothermal alteration.
Hole RMSAR-21-002 returned the strongest pathfinder element response (from 133 metres to 363 metres) in two hydrothermal zones (from 90 to 232 metres and 292 to 370 metres (bottom of hole and open at depth). The first interval is associated with gypsum/kaolinite and the second with montmorillonite. Partial oxidation of sulphides (pyrite) observed throughout this hole. The high Tl values in this hole are also considered indicative of a hydrothermal phase.
Holes ALNAR-21-001, ALNAR-21-002 and RMSAR-21-001 did not show any significant geochemical indication of being close to mineralization. This may reflect a paleo-elevation control and suggests these holes were collared too high in the system.
