Southern Silver drills 4.3 m of 387g/t AgEq at Cerro

Southern Silver Exploration Corp. has released further assay results which continue to extend both shallow gold-silver enriched oxide mineralization and high-grade polymetallic sulphide mineralization at the South Skarn and Mina La Bocona target areas on the Cerro Las Minitas project, Durango, Mexico.

Newly released polymetallic sulphide intercepts from the Mina La Bocona target area include:a 2.1 metre interval (1.8 metre est. TT) averaging 161g/t Ag, 0.1g/t Au, 4.9% Pb and 3.0% Zn (445g/t AgEq) including a 0.5 metre interval (0.4 metre est. TT) averaging 422g/t Ag, 0.4g/t Au, 13.2% Pb and 9.1% Zn (1229g/t AgEq) from drill hole 21CLM-151; anda 4.3 metre interval (2.6 metre est. TT) averaging 159g/t Ag, 0.1g/t Au, 2.4% Pb and 3.5% Zn (387g/t AgEq) including a 0.5 metre interval (0.3 metre est. TT) averaging 428g/t Ag, 0.2g/t Au, 0.1% Cu, 6.1% Pb and 1.5% Zn (705g/t AgEq) from drill hole 21CLM-148;

Mineralization identified in drill holes 21CLM-148 and -151 continues to extend earlier identified high-grade sulphide mineralization for up to 450 metres down dip and an approximate 250 metre strike-length at the Mina La Bocona target.

This recent drilling at the South Skarn target continues to extend that zone laterally to the southeast and up-dip from earlier reported mineralization in this target area including shallow gold-enriched oxide mineralization from drill hole 21CLM-154 (2.2m est. TT averaging 77g/t Ag, 1.1g/t Au) and deeper, higher-grade gold in sulphides from drill hole 21CLM-155 (1.1m est. TT grading 149g/t Ag and 8.8g/t Au).

Other mineralized intervals of note from the South Skarn target include:an 18.1 metre interval (14.0 metre est. TT) averaging 162g/t Ag, 0.2g/t Au, 1.4% Pb and 0.5% Zn (242g/t AgEq) including a 0.6 metre interval (0.4 metre est. TT) averaging 1150g/t Ag, 0.1g/t Au, 6.0% Pb and 2.7% Zn (1485g/t AgEq) from drill hole 21CLM-155; anda 1.1 metre interval (1.0 metre est. TT) averaging 227g/t Ag, 0.1g/t Au, 3.7% Pb and 1.9% Zn (423g/t AgEq) from drill hole 21CLM-154;

Drilling in 2020-21 on the South Skarn target has now demonstrated continuity of the polymetallic mineralization for over 350 metres along strike and up to 400 metres down dip. Two additional holes have been completed on the northern end of this target. Assays are pending.Figure 1: Plan Map of the Area of the Cerro showing the distribution of the CLM deposits and the location for new drill targeting, at the Mina La Bocona, South Skarn and Las Victorias targets.To view an enhanced version of Figure 1, please visit:

Exploration on the project continues with two drills on the property; the current program has now completed 54 core holes totaling 20,207 metres since drilling recommenced in September 2020. Assay results from 11 drill holes are pending and are anticipated over the coming weeks.

Southern Silver has now tested over 750 metres of strike length along the east side of the Cerro to depths of up to 500 metres, primarily in the South Skarn and Mina La Bocona target areas. Three bonanza grade mineralized zones have been identified and testing of a potential fourth high-grade zone is nearing completion, results of which will be incorporated into the upcoming mineral resource update on the project.

The CLM Project remains one of the largest undeveloped silver-lead-zinc projects in the World and is wholly owned, unburdened by royalties, fully financed and fully permitted.

Cerro Las Minitas Project

The Cerro Las Minitas project is an advanced exploration stage polymetallic Ag-Pb-Zn-Cu Skarn/CRD project located in southern Durango, Mexico.

The Cerro Las Minitas project as of May 9th, 2019 contains a Mineral Resource Estimate, at a 175g/t AgEq cut-off, of(1)Indicated – 134Moz AgEq: 37.5Moz Ag, 40Mlb Cu, 303Mlb Pb and 897Mlb Zn Inferred – 138Moz AgEq: 45.7Moz Ag, 76Mlb Cu, 253Mlb Pb and 796Mlb Zn

A total of 150 drill holes for 67,375 metres has been completed on the CLM Project with exploration expenditures of approximately US$27.0 million equating to exploration discovery costs of approximately C$0.09 per AgEq ounce to the end of 2020.

Analyzed by FA/AA for gold and ICP-AES by ALS Laboratories, North Vancouver, BC. Silver (>100ppm), copper, lead and zinc (>1%) overlimits assayed by ore grade ICP analysis, High silver overlimits (>1500g/t Ag) and gold overlimits (>10g/t Au) re-assayed with FA-Grav. High Pb (>20%) and Zn (>30%) overlimits assayed by titration. AgEq and ZnEq were calculated using average metal prices of: US$20/oz silver, US$1650/oz gold, US$3.25/lbs copper and US$0.9/lbs lead and US$1.15/lbs zinc. AgEq and ZnEq calculations did not account for relative metallurgical recoveries of the metals. Ore-grade composites are calculated using a 80g/t AgEq cut-off in sulphide and 0.5g/t AuEq in the oxide gold zone Composites have <20% internal dilution, except where noted; anomalous intercepts are calculated using a 10g/t AgEq cut-off.

Copper Fox completes IP survey at Mineral Mountain

Copper Fox Metals Inc. has released the results of a reconnaissance-style, deep-penetrating induced polarization (chargeability/resistivity) survey on its 100-per-cent-owned Mineral Mountain project, located approximately 16 miles northeast of Florence, Ariz.


  • A positive chargeability anomaly with approximate dimensions of 2,900 metres by 1,300 metres has been outlined. The anomaly is open to the southwest.
  • In the northern portion of the IP survey area, the chargeability anomaly correlates with the copper-molybdenum mineralization in outcrop and postmineral faults that control the limits of the mineralization.
  • A positive resistivity anomaly (600 m by 400 m) occurs within the chargeability anomaly and coincides with a zone of copper-molybdenum mineralization with molybdenum concentrations ranging from 20 to 1,700 parts per million in outcrop.
  • The results of an independent property reconnaissance over approximately 363 acres of the project concluded; no acuna cactus were observed, the potential for archaeological sites is low to moderate, and no evidence of leaks, spills, or potential sources of contamination was observed.

Elmer B. Stewart, president and chief executive officer of Copper Fox, stated: “The IP survey has provided the certainty required to plan a diamond drill program to test several high-potential copper-molybdenum exploration targets. The chargeability and resistivity anomalies exhibit a strong correlation to the copper and molybdenite mineralization in outcrop, postmineral faulting, and geochemical vectoring studies. The property reconnaissance survey established a background for the project and will provide definitive information when filing a geological field operations plan to conduct drilling operations.”

Geological model

The project covers a multiphase, Laramide-age intrusive stock, approximately five kilometres by two kilometres. The western portion of the stock exhibits sporadic, weak propylitic alteration and is not mineralized. The eastern portion of the stock exhibits altered, mineralized and non-mineralized granodiorite and quartz monzonite phases cut by syn-mineralization and late-stage dikes. The Laramide stock is interpreted to dip to the east under the Precambrian rocks. The western edge of the copper mineralization is defined by regional scale north-south- and east-northeast-trending faults. The mineralized zone exhibits early stage potassic alteration, overprinted by pervasive sericite and late-stage propylitic alteration phases with copper-epidote veining. The mineralization in outcrop consists of malachite, covellite and chalcocite resulting from the transformation of primary chalcopyrite related to weathering/oxidization/ enrichment processes after the Laramide hydrothermal event.

Geophysical study

The chargeability anomaly correlates with the limits of the mineralization and faults that define the limits of the mineralization. The chargeability anomaly is interpreted to plunge to the southwest and extends from 200 m to 400 m east of the intrusive contact under the Precambrian rock. The Precambrian rock along the intrusive contact hosts a significant number of copper showings. The resistivity anomaly correlates with an area of abundant quartz vein hosted copper-molybdenite mineralization that returned molybdenum concentrations ranging from 20 to 1,700 ppm.

Property reconnaissance

Copper Fox contracted SWCA Environmental Consultants to document the predrilling conditions within a 363-acre area of the project. SWCA reviewed historical and recent aerials, USGS topographic maps and Google Earth (2021) imagery to identify any human-made structures and landscape modifications. SWCA also reviewed the files in the AzSite database, including records from the Arizona State Museum, Arizona State University and Bureau of Land Management (BLM) to determine the existence of previously recorded archaeological sites within the property.

The property reconnaissance did not observe any acuna cactus within the area. The IP survey had previously been suspended pending completion of an environmental assessment requested by the BLM regarding concerns related to the acuna cactus. The location and environmental setting also suggest the potential for archaeological sites within the area is low to moderate, and no evidence of leaks, spills, or potential sources of contamination was observed.

Geophysical survey procedures

The induced polarization survey (12.2 km) was commissioned to Geofisica TMC (Simon McCrory, operator). Station markers were set at 50 m intervals using a Garmin GPS (UTM12N_NAD83). The survey consisted of three northwest-50-degree-oriented profiles approximately 1.15 km apart ranging in length between 2.5 and three kilometres, labelled L-1N, L-2N and L-3N, and a 4.2-kilometre-long base line (L-10E), which crosscuts the three other lines in the central part of the property.

The pole-dipole (dipole-pole) array chosen has a nominal A spacing between the electrodes of 100 metres and the separation factor between the dipoles varied form n equals one to 12 for the survey. A Walcer Geophysics TX-KW10 Generator (10 kilowatts) and a GDD Instrumentation GRX8-32 Time Domain Receiver were used to collect the data. Two-dimensional pseudo-sections and IP maps at a 1/10,000 scale of the resistivity and chargeability inversion models was prepared at vertical depths of 100 and 300 m.

Mr. Stewart, MSc, PGeol, president and chief executive officer of Copper Fox, is the company’s non-independent, nominated qualified person pursuant to National Instrument 43-101, Standards for Disclosure for Mineral Projects, and has reviewed and approves the scientific and technical information disclosed in this news release.

Anaconda drills 29.4 m of 1.54 g/t Au at Stog’er Tight

Anaconda Mining Inc. has released the results from 1,028 metres of a 5,158-metre infill drilling program at Stog’er Tight. The Stog’er Tight deposit is located three kilometres from the Pine Cove mill and tailings facility, and the company has commenced permitting activities related to the development of the area in conjunction with the infill drilling. The results of the infill drill program are consistent with results from previous drill programs and also identified two broad intersections of mineralization near the northern portion of the deposit. The results of the complete infill drill program, of which 773 metres remain outstanding, will be used to finalize geological and resource modelling of this portion of the Stog’er Tight deposit, which will form the basis of pit design and potential development scenarios.

Highlights of the drill program include:

  • 1.54 grams per tonne gold over 29.4 metres (6.6 to 36 metres), including 15.90 g/t gold over one metre in diamond drill hole BN-21-470;
  • 4.72 g/t gold over seven metres (64 to 71 metres), including 19.50 g/t gold over one metre; and 0.84 g/t gold over 10 metres (27 to 37 metres) in diamond drill hole BN-21-468;
  • 1.60 g/t gold over 15.4 metres (35.6 to 51 metres), including 8.10 g/t gold over 0.5 metre in diamond drill hole BN-21-474;
  • 1.30 g/t gold over five metres (38 to 43 metres) in diamond drill hole BN-21-477.

Selected intersections from the infill drill program at Stog’er Tight are shown in the attached table.

“We continue to be encouraged by the results from our infill drill program at Stog’er Tight. The most recent drill results, particularly the broad zones of mineralization starting near surface, are promising, with the intercept from hole BN-21-470 being approximately three times the thickness of intercepts on either side. The drill results to date have provided the confidence to proceed with internal resource estimates, pit designs and plans for potential development. We have consequently moved forward with associated permitting work for the possible development of the Stog’er Tight area, which has the near-term potential to extend the life of mine at Point Rousse. With the success at Stog’er Tight providing insight into other prospective near-mine opportunities, we anticipate the initiation of a broader exploration program at Point Rousse to support continued gold production in the Baie Verte peninsula, where we operate the only producing gold mine and mill in Newfoundland,” said Kevin Bullock, president and chief executive officer, Anaconda Mining.

The Stog’er Tight deposit is located three kilometres east of the Pine Cove mill, adjacent to existing road networks, and has been defined over a strike length of 1,250 metres to date. Anaconda produced a total of 17,102 ounces of gold from 349,942 tonnes of ore from the Stog’er Tight mine between June, 2018, and January, 2020. Gold from Stog’er Tight was recovered through the Pine Cove mill with an average head grade of 1.75 g/t gold at an overall recovery of approximately 87 per cent.

Preliminary environmental studies have been initiated at the expanded Stog’er Tight deposit, including environmental baseline work associated with Camp Pond, which is anticipated to be impacted by potential development west of the Stog’er Tight mine. Fox Pond, located east of Camp Pond, was similarly underlain by the Stog’er Tight deposit, which was successfully mined in 2018 and 2019 by partial dewatering of the pond under appropriate provincial and federal government authorizations. The company also continues to gather baseline data to support the submission of an enhanced environmental registration document to regulators early in the fourth quarter of 2021. In addition, fish and fish habitat data are being collected to support the development of a Fisheries Act Authorization application and a fish habitat offsetting plan, which is also expected to be submitted in the fourth quarter.

This news release has been reviewed and approved by Paul McNeill, PGeo, vice-president of exploration with Anaconda Mining, a qualified person, under National Instrument 43-101 Standard for Disclosure for Mineral Projects.

All samples and the resultant composites referred to in this release were collected using quality assurance/quality control protocols including the regular insertion of certified standards and blanks within each sample batch sent for analysis and completion of check assays of select samples.

HPQ to develop fumed silica plant with PyroGenesis

HPQ-Silicon Resources Inc.’s HPQ Silica Polvere Inc., a 100-per-cent-owned HPQ subsidiary, and PyroGenesis Canada Inc. have signed a development agreement covering the fumed silica reactor industrial pilot plant development program and the future commercialization of fumed silica materials made with this newly developing green, proprietary and low-cost manufacturing process. Figures 1 and 2, below, show the dramatic simplification of the new process compared to today’s conventional process. Figure 1) From to Quartz to Fumed silica {െ –} One Step New process from HPQ and PyroGenesis

Figure 1 is available at Figure 2) From to Quartz to Fumed silica {྽ –} complex conventional process and by-products


As Figure 1 illustrates the new process, invented by PyroGenesis Canada Inc, represents a paradigm shift in the manufacturing of Fumed silica (Pyrogenic Silica). The new plasma-based process allows a direct Quartz to Fumed silica transformation, removing the usage of hazardous chemical in the making of Fumed silica and eliminating the Hydrogen Chloride Gas (HCI) associated with its manufacturing. Furthermore, the process requires 15,000 kWh to produce a MT of Fumed Silica, this represents a staggering 86% reduction in the energy footprint associated with manufacturing Fumed Silica. Finally, since the new process uses Quartz as feedstock, its capital requirements will only be a small fraction of what is required to build a traditional Fumed Silica plant.


As Figure 2 demonstrates, conventional processes to manufacture fumed silica is a complex multi-step process that requires significant energy consumption (110,000 kWh to produce one Metric Tonne (MT) of Fumed Silica), involves many hazardous products and generates extreme by-products in the form of Hydrogen Chloride Gas (HCI), a highly regulated gas with stringent environmental constraints associated with its use. Traditional processes to make fumed silica are highly capital intensive, as the Silicon Tetrachloride feedstock necessary to the fumed silica manufacturing process can only be made by a Polysilicon plant, requiring > US$ 1.2 billion investment for 10,000 Metric Tonne per Year (MTA) capacity1 to which you must add the > US$ 150 million cost to build a production line capable of producing 13,000 MTA2 of fumed silica.


Fumed silica (Pyrogenic Silica) is a white microscopic powder with high surface area and low bulk density. Its commercial applications encompass various industries including personal care, pharmaceuticals, agriculture (food & feed), adhesives, sealants, construction, batteries and automotive to name a few. Demand for Fumed Silica is growing at 6% CAGR, with a global addressable market of US$ 1.5 billion in 2016 expected to grow to US$ 2.2 billion in 2022, but present manufacturing processes are hindering its growth potential.


The key areas covered by the agreement between HPQ POLVERE and PyroGenesis are:

FUMED SILICA REACTOR 50 MT per Year industrial pilot plant development program, schedule and cost assumed by HPQ POLVERE,

Acquisition of the FUMED SILICA REACTOR PROCESS Intellectual Property as it relates to the manufacturing of Fumed Silica by HPQ POLVERE,

Revenue distribution between HPQ POLVERE and PyroGenesis from the sales of Fumed Silica materials made with the FUMED SILICA REACTOR PROCESS .

The FUMED SILICA REACTOR industrial pilot plant development program is made of three phases.

Completing the engineering related to the fabrication of the pilot plant, To be completed by December 1st, 2021, HPQ POLVERE contribution to this phase of the program is $109,433,

Completing the fabrication, assembly, and Installation of the Pilot plant To be completed by July 15, 2022, HPQ POLVERE contribution to this phase of the program is $207,046,

Completing the commissioning, start-up, and operation of the Pilot Plant, This Phase is schedule to start on July 16, 2022, and run until March 1, 2023. HPQ POLVERE contribution to this phase of the program is $284,021.


The agreement also covers HPQ POLVERE acquisition of the intellectual property rights to the Fumed Silica Reactor Process as it relates exclusively to the production of Fumed Silica (Pyrogenic Silica) (the “Field”) from PyroGenesis. The acquisition cost of the Fumed Silica Reactor Process IP is CAD$3,300,000.

PyroGenesis will retain a royalty-free, exclusive, irrevocable worldwide license to use the process for purposes other than the production of Fumed Silica (Pyrogenic Silica). Should PyroGenesis be approached by any other parties for any research and development or commercial purposes outside of the Field, HPQ POLVERE shall have a right of first refusal, provided that, however, HPQ POLVERE exercise its right of first refusal within thirty (30) days of PyroGenesis receiving a bona-fide offer.


The autonomous potential of this project is such that it was deemed more efficient for HPQ Silicon to create, from the start, a fully own subsidiary, HPQ Silica Polvere Inc, to be the stand-alone Corporation that would finance HPQ contribution to the pilot plant program, through loans from parent company HPQ, the acquisition of the IP and manage the future commercialisation of Fumed Silica (Pyrogenic Silica) materials made with the Fumed Silica Reactor Process.

As with all our other transactions with PyroGenesis, HPQ POLVERE agrees to pay PyroGenesis, on an annual basis, a minimum royalty (Pyrogenic Silica Royalty), with PyroGenesis being granted the right to convert, at any time and at its sole discretion, its Royalty into a 50% equity stake in HPQ POLVERE.

As a result of this, HPQ POLVERE agrees to pay PyroGenesis, on an annual basis, and until conversion, the following minimum royalty (Pyrogenic Silica Royalty), on the gross sales of Pyrogenic Silica, excluding samples and testing products, produced with any Systems incorporating the Reactor and Process IP and/or the Optioned Rights:

For 2023, the greater of 10% of HPQ POLVERE gross sales or fifty thousand Canadian dollars (CDN$50,000),

For 2024, the greater of 10% of HPQ POLVERE gross sales or one hundred thousand Canadian dollars (CDN$100,000),

For 2025, the greater of 10% of HPQ POLVERE gross sales or one hundred and fifty thousand Canadian dollars (CDN$150,000),

For 2026 and beyond, the greater of 10% of HPQ POLVERE gross sales or two hundred thousand Canadian dollars (CDN$200,000).

“With over 25 years of expertise in torch plasma applications, PyroGenesis is a market leader in green deployment of plasma technologies. As the project enter the industrial Pilot Plant development phase, we are very excited to have been chosen to participate in this new venture with PyroGenesis. The business opportunity that this represent should not be underestimated and could be as significant as the ones represented by the PUREVAP{㎡ ™} family of processes we are developing with PyroGenesis,” said Bernard Tourillon, President and CEO HPQ Silicon. “Over US$50 billion in capital flowed in US ESG funds in 2020, and these are the types of investment they are looking for, so our timing could not be better. Our market research has identified several sectors wishing to improve their environmental footprint, and HPQ’s innovative silicon solutions is prepared to meet this demand.”

“This Agreement represents another significant milestone in our relationship with HPQ and, once again, underscores the many hidden opportunities within this partnership,” said M. P Peter Pascali, President and CEO of PyroGenesis. “This Contract is another testament to PyroGenesis’ solid position as an emerging leader in GHG emissions reduction. In fact, this opportunity is a natural extension of what is being targeted by the Company, and aligns itself well with environmental initiatives currently taking place worldwide.”
