Tocvan Reports 92% Recovery of Gold from Preliminary Metallurgical Results

 

(TheNewswire)

   

  Provides Update on Phase II Drill Program  

 

Calgary, Alberta - TheNewswire May 4, 2021 . TOCVAN Ventures Corp. ( CSE:TOC) (CNSX:TOC.CN) (" Tocvan " or the " Corporation ") is pleased to announce the results of ongoing metallurgical work at its flagship Pilar Gold-Silver Project in Sonora, Mexico. Preliminary results have been received from two composite samples taken from the previously released drill hole JES-20-32. Drill hole JES-20-32 is thought to be representative of the central portion of the Main Zone, which during Phase I drilling in December of 2020 intersected 94.6-meters at 1.6 gt Au including 9.2m at 10.8 gt Au and 38 gt Ag from 57.9 to 152.5 meters.  The samples consisted of a low-grade (0.63 gt Au) and a medium-grade (1.2 gt Au) composite to determine the susceptibility of dissolution of gold through cyanide bottle testing. The results show after a retention time of 48 hours, maximum dissolution can be reached of 91% for the low-grade composite and 92% for the medium-grade composite.  A summary of the results are provided in Table 1. Samples were submitted to SGS Laboratories in Durango, Mexico for analysis.

  "These results are an important first step as we move towards a bulk sample at Pilar," commented VP Exploration, Brodie Sutherland. "The results align with analysis completed by past operators which displayed similar gold recoveries of 90 to 92%. With our Phase II drill program well underway we will continue to evaluate the potential of Pilar with continued exploration and metallurgical studies leading towards a bulk sample later this year."  

 

  Update on Phase II Drill Program  

 

  A minimum of 14 drill holes totalling 2,400 meters is planned for the initial stage of the Phase II drill program. Eight drill holes have been completed to date for a total of 1,394 meters. Samples for the first three holes have been submitted to ALS Labs in Hermosillo, with the remaining holes expected to be shipped and submitted this week. Early drilling has focused on the extension of the Main Zone. Drill targeting is now shifting towards testing new targets in the 4-Trench Extension, North-Hill and Triple Vein Zone areas. A second stage of drilling totalling 1,600 meters is planned to commence mid-May which will continue to test property wide targets and follow-up on results from the initial stage.  

 

  Corporate Update  

 

  Tocvan is also pleased to report it has granted 200,000 share options to a consultant of the company. The options are exercisable at $0.80 per share with a 5-year term to expiry and will vest over a one-year period.

  About the Pilar Property  

 

  The Pilar Gold-Silver property is interpreted as a structurally controlled low-sulphidation epithermal project hosted in andesite rocks.   Three zones of mineralization have been identified in the north-west part of the property from historic surface work and drilling and are referred to as the Main Zone, North Hill and 4-Trench. Structural features and zones of mineralization within the structures follow an overall NW-SE trend of mineralization. Over 19,200 m of drilling have been completed to date. Significant results are highlighted below:

  Soil and Rock sampling results from undrilled areas indicate mineralization extends towards the southeast from the Main Zone and 4-Trench Zone. Recent Surface exploration has defined three new target areas: Triple Vein Zone, SE Vein Zone and 4 Trench Extension.  

 

  Brodie A. Sutherland, P.Geo., VP Exploration for Tocvan Ventures Corp. and a qualified person ("QP") as defined by Canadian National Instrument 43-101, has reviewed and approved the technical information contained in this release.  

 

  Sampling Methods  

 

  Samples collected for metallurgy are composites of RC chips with a minimum weight of 15kg   .   Composites were shipped to SGS Durango, Mexico. Gold recovery was analyzed by cyanide bottle roll test.

Top 5 Australian Mining Stocks This Week: Yandal Shares Double on Arrakis Drilling Results

Welcome to the Investing News Network's weekly round-up of Australia’s top-performing mining stocks on the ASX, starting with news in Australia's resource sector.

This week's top-performing stocks list is dominated by oil and gas companies, alongside gold and lithium companies.

In Australian mining news, the Fair Work Commission ruled that BHP (ASX:BHP,NYSE:BHP,LSE:BHP) must raise the wages of 2,200 workers at three coal mines in Queensland. The workers in question were employed indirectly through a hiring firm and were being paid significantly less than their peers working directly under BHP.

The case was brought by two worker's unions and based on the Same Job, Same Pay reforms made by the government last year. To align wages, the FWC ruled BHP must raise the labour hire employees' wages by AU$30,000 each.

Pilbara 2.0: Inside Australia’s Newest Gold Frontier

The Central Pilbara region of Western Australia is undergoing a quiet revolution that is rapidly reshaping the global gold exploration landscape.

Once dismissed as a technically challenging and geologically inconsistent terrain, Pilbara is now emerging as one of the world’s most exciting new gold frontiers and drawing serious attention from institutional investors, driven by transformative discoveries, a maturing geological model and a wave of junior explorers tapping into underexplored intrusive-hosted systems.

Anchored by the multimillion-ounce Hemi discovery — one of the most significant gold finds in Australia in over a decade — this region is not just proving its geological potential, but also demonstrating the kind of scale, consistency and margin profile that modern gold investors seek. As the discovery window remains wide open and valuations are still accessible, the Central Pilbara presents a rare opportunity for early exposure to what may become one of Australia’s next tier-one gold districts.
