Arcpacific Trenches 36 Metres Of 1.03 Gold Eq. (Au & Ag) In First Ever Trenching At Blackdome

ArcPacific Resources Corp. (TSX-V: ACP) is pleased to report that the entire length of both trenches completed at the Blackdome project (the “Property”) in British Columbia, Canada, showed anomalous to high-grade gold and silver values. With the both trenches returning grater than 1 gram per tonne (“g/t”) gold equivalent (“AuEq”) (using gold and silver values only) over their entire lengths, and up to 7.35 g/t gold over a 1-meter segment. These results confirm epithermal-style gold-silver mineralization at the Property and indicate that it is likely responsible for the 1 by 2-kilometre gold-in-soil anomaly (see Figure 1 below).  Geochemical evidence (including elevated antimony, arsenic and mercury) also suggests that the level of exposure is at a high level within the epithermal system, leaving significant potential for the entire extent of the precious metal or gold rich portion of the system to be intact.


  • High grades of gold, up to 8.23 g/t, are associated with epithermal quartz veining showing vuggy, bladed, crustiform and colloform textures.
  • A high-grade gold sample of 8.37 g/t was returned from silicified siltstone indicating the potential for broader zones of mineralization to exist within proximal permeable geological units.
  • There is no record the Property has ever been drilled.
  • Abundant quartz vein float observed along the main ridge are likely from nearby sources.
  • Gold and silver grades are associated with antimony (Stibnite) indicating the system is only exposed at a high level possibly leaving the best potential bonanza grade and stockwork zones below and intact.

Adrian Smith CEO of ACP comments, “We are very pleased with the results from the first-pass program that was able to generate meaningful results, this speaks volumes for the potential at the Property. We are confident that we are sitting on an epithermal gold silver system existing within the bounds of the Property and based on the geochemical signatures, it looks like we are still sitting above what could potentially be the bonanza grade portion of the system. Based on these positive initial results we have now begun the permitting process to advance this project to the next stage including additional trenching and drilling.”

1) Gold Equivalent (Eq) was calculated with the following metal prices; Gold (Au) $1800/oz and Silver (Ag) $25/oz. All metals reported in USD and calculations do not consider metal recovery.
2) Intervals taken as chip samples along approximate mineralized trends; true widths are unknown at this time.
3) Antimony values are not included in the Gold Equivalent (AuEq).
4) Antimony values are capped at 1% due to sample values exceeding assay limitations of 1%.

Figure 1: 2021 Sample and Trenching Location Map over historic soils and geology.

Due to the limited scope of this initial program, only 2 of 6 known target areas were tested, and over 80% of the Property remains untested. Test pitting along the top of the ridge area was unsuccessful in reaching bedrock where historical float samples have run up to 19.3 g/t gold.

The elongated and unvegetated ridge is the center of the 1 by 2-kilometre open-ended gold in soil anomaly (shown above), where the next phase of planned work will require mechanical trenching or drilling to properly test the multiple target areas within this wide anomaly.

The hand trenching completed in this program represents the first trenching completed on the Property. Trenching locations were selected based on historic soil, grab and outcrop samples, where the historic samples include up to 54 grams per tonne gold in rocks and over 4 grams per tonne in soils. Based on the location of the float samples along the crest and margins of the broad ridge, it is probable that they are also locally derived.

Figure 3: Sample D365253; Float sample showing vuggy bladed and sugary quartz typical in epithermal gold-silver deposits.

The samples taken as part of the first-pass program (see table 2 above) were predominantly quartz and quartz carbonate vein material often displaying epithermal characteristics including crustiform, colloform, chalcedonic, banded, bladed, and vuggy textures and locally including up to 1% sulphides. Massive stibnite was also observed in 1–4-centimeter seams in quartz vein margins in the Stibnite Zone.

Figure 4: Geological Model (from Buchanan (1981)) of an epithermal gold-silver system. Showing the possible current surface and relative exposure level high in the system as indicated by the elevated arsenic and abundant stibnite associated to some of the gold and silver mineralization present at the Property.

Substantial grades of antimony (often exceeding the assay limit of 1%) along with the elevated levels of arsenic indicate the epithermal system is exposed at a high level as shown in the Blackdome Geological Model above (see Figure 4). This model is based on a type-example of a Low Sulphidation (“LS”) epithermal system and suggests that that the best gold and silver grades are still located in a potential bonanza grade zone below. There is no record that the Property has ever been drilled.

The Property covers a prospective 3,479 hectares over an epithermal gold-silver exploration target in Southern, British Columbia. The Property is 60 kilometres south of the 1.6-million-ounce gold Newton deposit, 20 kilometres south of the 5.3-billion-pound copper and 13.3-million-ounce gold New Prosperity deposit and 65 kilometres north of the prolific Bralorne gold camp in southern, British Columbia which has produced over 4 million ounces and remains as an active gold mining camp.

All samples were submitted to ALS Laboratories in Vancouver, British Columbia, Canada and analysed using 4-acid digestion with ICP-MS finish for multi-element analysis and Au 30g fire assay with ASS for gold values. Standards, duplicates, and blanks were included as part of the laboratories independent QAQC procedure.
