VANCOUVER, British Columbia, Jan. 11, 2022 (GLOBE NEWSWIRE) — Apollo Silver Corp. (“Apollo” or the “Company”) (TSX.V:APGO, OTCQB:APGOF, Frankfurt:6ZF) is pleased to provide an update on its ongoing technical review of historic data at the Waterloo and Langtry projects in San Bernardino County, California. Recently this work has identified a 25 metre (“m”) thick, gold bearing horizon below silver mineralization. Silver mineralization transitions to gold-dominated mineralization at the variably faulted lithologic contact between Barstow formation sedimentary rocks and Pickhandle formation volcaniclastics. Gold mineralization at the district’s only historic gold producer, the Burcham Mine, occurs along this contact 250 m to the southeast. Apollo’s analysis of historic data has shown that not only does gold mineralization extend beyond the Burcham mine area, evidence suggests that at the Waterloo project the entire 2.2 kilometre (“km”) long contact between the Barstow sediments and Pickhandle volcaniclastics is prospective for gold mineralization.
- Potential for meaningful gold mineralization along the entire 2.2 km long contact for which the majority of historic drill holes did not test;
- Gold (“Au”) mineralized horizon of 25 m (true thickness) returning 0.59 grams per tonne (“g/t”) Au from 132.60 m below surface, including 1.52 m of 5.52 g/t Au. This horizon is 60 m wide and 110 m length (down-dip) and open in all directions;
- The contact represents an excellent exploration target for replacement style gold mineralization, and possibly higher-grade vein hosted gold; and
- The upcoming 2022 drill program will test for additional gold mineralization along this prospective horizon.
“Our systematic approach to reviewing and validating the historic data is continuing to deliver significant value” Apollo CEO, Tom Peregoodoff, commented. “We were aware of this historic gold production at the Burcham mine, however it is only recently and through this detailed review that we have come to understand the nature and extent of the host unit, and the potential for a significant gold discovery at Waterloo. This presents an exciting opportunity in that it substantially adds to the exploration potential of the properties and testing of this prospective horizon will form part of our upcoming 2022 drill program. With our pending maiden silver resource declaration for Waterloo and Langtry on track, 2022 is shaping up to be a very exciting year for Apollo.”
Gold Mineralization at Calico
Apollo’s Waterloo project hosts the Burcham mine, the only mine in the Calico Mining District known to produce gold as its primary commodity (refer to Figure 1). Gold was produced from two NW-oriented veins via underground drifts. Gold is hosted in veins varying from 0.3 up to 3 m wide and occurs as replacement style mineralization, with both the Barstow and the Pickhandle volcaniclastics formations hosting disseminated gold in zones up to 9 m wide. Gold was reported to be associated with chalcopyrite, galena, sphalerite and silver chloride, all hosted in a gangue of quartz, barite and iron oxides. There are no known production numbers from this mine, but historic public articles report grades of up to 0.31 ounces per ton (9.7 g/t).
Historic Mining and Exploration for Gold at Calico
ASARCO undertook a number of work programs to better understand gold mineralization in the Burcham area between 1985 and 1989. These included 10 shallow air track holes (188 m total, maximum depth of 29.30 m), three diamond drill holes (335.30 m total, maximum depth of 137.60 m) and underground chip/channel sampling (96 samples, 3-6 m lengths, ~5 kilograms each) from accessible underground workings. A selection of results of gold mineralized intersections from this drilling are shown in Table 1. Results from the underground chip sampling revealed a maximum of 2.01 g/t Au (average 0.63 g/t Au) in the Pickhandle volcaniclastics (12 samples) and a maximum of 4.44 g/t Au (average 0.44 g/t Au) in the Barstow sediments (84 samples). Importantly, this is the only work program completed by Asarco that included assaying for gold.
Between 2008 and 2012, Pan American Minerals, a wholly owned subsidiary of Pan American Silver Corp. (“Pan American”), completed exploration programs comprising surface geological mapping and drilling. Six reverse circulation holes completed by Pan American show a transition from silver-dominated mineralization to gold-dominated mineralization towards the SW-dipping, unconformable and variably faulted contact between the Barstow and Pickhandle formations. This gold-dominated horizon is up to 25 m thick (true thickness), 60 metres wide, 110 m long and is open in all directions (refer to Figure 2), as identified in drill hole W-0054, which intersected 0.59 g/t Au from 132.60 m downhole, including 7.62 m of 1.44 g/t and 1.52 m of 5.52 g/t Au.
Geological mapping completed by Dr. Warren Pratt in 2008 (for Pan American) identified hydrothermal mineralization along the entire 2.2 km length of the contact on the Waterloo property. Some areas were intensely altered to an acid-sulfate assemblage of kaolinite, alunite and cristobalite, particularly in the volcaniclastics. Acid sulphate type leaching is widespread at surface at the contact in both the Barstow and Pickhandle formations, and the contact appears to be variably mineralized for at least half its length, as hematite, jarosite, goethite, quartz and copper oxides were observed. Historic mining at both the Burcham and Waterloo mines exploited this contact.
Conclusions – Gold Exploration Potential
Apollo’s analysis of historic Pan American and ASARCO data has concluded that not only does gold mineralization extend beyond the Burcham mine area, there is evidence to suggest that the entire 2.2. km long contact between the Barstow sediments and Pickhandle volcaniclastics is prospective for gold. Historic work by ASARCO demonstrated that the Barstow formation and a wide halo in the Pickhandle volcaniclastics in the Burcham area are mineralized with disseminated gold. Spatial distribution and both Pan American and ASARCO drill log data suggest this is a replacement style mineralized zone preferentially formed along the contact between the Barstow and Pickhandle formation, with the Pickhandle volcaniclastics being the preferential gold host. Shallow drilling by ASARCO and evidence from geologic mapping completed by Pan American suggest this mineralization extends to surface. All gold mineralization occurred in oxidized rock.
Of the 277 drill holes in Apollo’s Waterloo database, only 18 definitively pierce the contact and have gold assays (see Figure 1). Thirteen of these holes are mineralized (i.e., +0.2 g/t Au). Of note is that many of the holes that pierce the contact do not fully test the adjacent volcaniclastics.
The current focus of the review has been on the Waterloo project. The gold potential at the adjacent Langtry property remains poorly constrained and work is ongoing to better assess this potential.
Testing of the gold prospective horizon will form part of the upcoming 2022 drilling program.
