MAS Gold reports maiden resource for North Lake

A maiden mineral resource for MAS Gold’s North Lake deposit in Canada’s Saskatchewan province, within the La Ronge gold belt features 14.1 million tonnes grading 0.92 g/t gold for a total of 417,000 oz.

MAS holds a total of 338 sq. km of ground within four properties in Saskatchewan’s La Ronge belt.

Based on a resource estimate from 2016, the Greywacke North deposit within these holdings features indicated resources of 225,500 tonnes at 9.92 g/t gold for a total of 81,500 oz. with further inferred resources of 59,130 tonnes grading 7.42 g/t gold totaling 14,100 oz.

Greywacke North includes both a near-surface as well as an underground component.

“The low-grade North Lake mineral resource, when combined with the high-grade deposit at Greywacke North, supports our strategic mine development plan that envisions a centralized plant processing material from North Lake, co-mingled with high-grade material from MAS Gold’s other La Ronge gold belt deposits,” Ron Netolitzky, the company’s president and CEO, said in a release.

The North Lake deposit, located within a section of the project known as ‘Preview North,’ remains open on strike and at depth; Netolitzky added that the company plans to continue with its exploration efforts to grow the resource inventory.

Additional drilling and supporting work is planned for this year for North Lake and surrounding Preview North targets to move this area towards a future preliminary economic assessment (PEA).

Exploration and metallurgical testwork is envisioned for Greywacke North as well, also to advance this deposit towards the PEA stage.

McEwen suspends mining at Black Fox and Gold Bar

After announcing a temporary suspension of operations until at least March 31 at its 49%-owned San José mine in Argentina late last week due to Covid-19, McEwen Mining reported today it will also be suspending production at its Black Fox mine in Ontario and Gold Bar in Nevada.

That leaves only the company’s small El Gallo residual heap-leach operation in Mexico operating.

The move to temporarily shut Black Fox comes despite the Ontario government giving mining and mineral exploration the designation of “essential” businesses this week

The move to temporarily shut Black Fox comes despite the Ontario government giving mining and mineral exploration the designation of “essential” businesses this week, exempting them from a two-week, province-wide shutdown of non-essential businesses.

While McEwen Mining said last week that it had various measures in place to combat the spread of the covid-19 at Black Fox, near Timmins – including site access restrictions and employee screening, not bringing in any staff who have to travel more than four hours by plane to get to the site, and the discontinuation of group meetings – it said the suspension would protect the health of its workers, their families and nearby communities.

At Black Fox, some development activities related to the access ramp for the Froome deposit, 900 metres from the Black Fox open pit, are expected to continue.

Some production and exploration activities where social distancing can be observed will also continue at Gold Bar. These include ore crushing, irrigation of the heap leach pad and operation of the process plant.

Minimal staff will remain at both sites to ensure safety, security and environmental compliance. Production at Black Fox last year was 35,720 gold-equivalent oz., with Gold Bar producing 30,710 gold-equivalent oz.

San José is majority-owned (51%) by Hochschild Mining.

The temporary closure of the gold-silver mine, which produced 91,654 attributable gold-equivalent oz. last year for McEwen, followed the declaration of a state of emergency and mandatory, nationwide quarantine by the government of Argentina.

El Gallo, in Sinaloa state, produced 16,333 gold-equivalent oz. in 2019 from residual leaching of the heap leach pad.

GoGold hits high grades at Los Ricos South

GoGold Resources’ (TSX: GGD) most recent exploration results include near-surface, high-grade silver and gold intersections around historical underground workings from the Los Ricos South project in Mexico.

The Main area returned 18.8 metres of 255 g/t silver-equivalent starting at 3 metres, 19.5 metres of 199 g/t silver-equivalent starting at 4.5 metres and 26.4 metres of 203 g/t silver-equivalent starting at surface.

“Drilling continues at Los Ricos with 6 drill rigs as we accelerate the drilling required for our initial resource,” Brad Langille, the company’s president and CEO, said in a release.

“At the Los Ricos North project, we continue with the groundwork preparing for an upcoming drill campaign, which we anticipate commencing after the Easter break.”

The eight holes reported are from the Main and San Juan areas, with extensive underground workings nearby. The company believes that gold and silver has been mined at Los Ricos since the 16th century.

GoGold has subdivided the 225-sq.-km project in Jalisco state into southern and northern portions. Drilling at Los Ricos South is currently focused around historical mines. Last year, the company drilled 17,400 metres at the project.

The company also announced that its operations were not affected by the spread of the covid-19 virus

On Mar. 18, the company also announced that its operations were not affected by the spread of the covid-19 virus and that it has implemented additional sanitization, monitoring and education efforts.

In March of 2019, the company entered into an option agreement to acquire Los Ricos and accelerated the acquisition in August by agreeing to pay a total of US$7.1 million in cash and shares over a 24-month period.

In February, GoGold closed a $25-million bought deal financing.

In addition, the company operates the Parral tailings project in Mexico’s Chihuahua state, which features two tailings sites with one currently producing silver.

Las Conchitas returns more gold for Mako

Mako Mining has released the results of six holes drilled to test the Bayacun zone at the Las Conchitas area within the San Albino project in Nicaragua, which intercepted high-grade gold and silver mineralization at shallow depths.

Highlights include 1.6 metres of 84.64 g/t gold and 80.2 g/t silver at 80 metres from surface as well as 3.9 metres of 25.78 g/t gold and 18.3 g/t silver at 45 metres from surface.

It appears that the drilling at the 2.5-sq.-km Las Conchitas area, which has been ongoing since 2019, has traced at least eight mineralized zones that are shallow dipping and high grade.

The latest results extended the Bayacun zone to 140 metres down-dip; it remains open both on strike and down dip

The latest results extended the Bayacun zone to 140 metres down-dip; it remains open both on strike and down dip.

“Every hole referenced in this press release hit significant gold mineralization,” Akiba Leisman, the company’s CEO, said in a release.

“The Bayacun zone of the Las Conchitas area is proving to be a predictable and high-grade target at relatively shallow depths.”

Leisman added that one drill rig is expected to continue exploration work at Las Conchitas, aimed at outlining a maiden resource for this area next year. Assays for an additional 19 holes, drilled to target Bayacun, are pending.

The Las Conchitas area is approximately 2.5 km south of the 500 t/d San Albino open pit project, which is under construction with a first gold pour expected in the fourth quarter.

Earlier this month, the company announced that it has reduced the number of people at the operation to reduce potential COVID-19 infection risks.

Although mining of gold mineralization was suspended as a result, Mako shifted its efforts towards earthworks and construction of the tailings facility.

The San Albino project covers a total of 150 sq. km and includes a 23-km strike of the Corona de Oro gold belt.

Amex intersects near-surface gold at Perron

Drilling at Amex Exploration’s Perron property in Quebec returned near-surface gold intercepts from the Gratien and Grey Cat zones in the western section of the 45-sq.-km project.

Grey Cat intercepts include 39 metres of 1.22 g/t gold at a depth of 80 metres as well as 10.3 metres of 4.54 g/t gold at a depth of 70 metres. The drilling, which was completed on a 25-metre spacing, suggests that the mineralization is contained within a single lens.

At the Gratien zone, drilling targeted the Gratien Main and Lower Gratien areas and intersected 9.2 metres of 1.18 g/t gold at approximately 80 metres depth

At the Gratien zone, drilling targeted the Gratien Main and Lower Gratien areas and intersected 9.2 metres of 1.18 g/t gold at approximately 80 metres depth and 3.3 metres of 1.66 g/t gold from a depth of 15 metres.

“These results indicate the continual expansion of the Grey Cat and Gratien (zones),” Jacques Trottier, the company’s executive chairman, said in a release.

“Going forward, we plan to continue to define a near-surface deposit at Gratien to approximately 250 metres vertical depth and will begin to test the Grey Cat to a depth of approximately 500 metres vertically. The Grey Cat appears to have a high-grade core that dips approximately 60 degrees to the east, similar to the Eastern Gold zone, which, in our experience, bodes very well for the depth potential of this target.”

To date, Amex has traced mineralization along a 3.2-km structural trend at Perron, within the Gratien, Grey Cat, Central Polymetallic and Eastern zones.

The project features a total of 15 km of structural targets over the Perron and Normetal faults with additional targets within the Beaupre block.

Amex previously announced that it was planning on completing a 60,000-metre drill campaign at Perron this year.

Nighthawk expands Colomac Main sill at depth

With the release of ten outstanding holes from the 2019 exploration program at its Indin Lake property in the Northwest Territories in Canada, Nighthawk Gold has expanded the under-explored central portion of the Colomac Main sill at depth.

The holes targeted zones 2.5 and 2.0 at the 899-sq.-km project.

Highlights include 36.1 metres of 1.86 g/t gold from a hole drilled below an area of historical shallow drilling, where uniform mineralization has been traced down to a depth of 260 metres as well as 28.5 metres of 1.26 g/t gold and 19.8 metres of 1.25 g/t gold.

The latter two intercepts targeted mineralization below a zone drilled in 2018, which extended mineralization at depth down to 250 metres and an area with a 150-metre gap in drilling, respectively.

The central portion of the Colomac Main Sill remains open and unexplored below 250 metres.

“Drilling on the Colomac Main has continued to demonstrate a consistency in breadth and continuity of mineralization throughout all areas of the deposit,” Michael Byron, president and CEO, said in a release.

“While the central 1-km section of Colomac Main remains largely unexplored, with few holes below 250 metres vertical depth, our current holes have tested the sill well below previous intersections, successfully extending mineralization to new depths.”

Infill drilling of near-surface areas has also confirmed historical intersections as well as their continuity at depth.

Current inferred resources for the project stand at 50.3 million tonnes grading 1.62 g/t gold for 2.6 million ounces

Based on its understanding that other areas of the sill widen with depth, Nighthawk believes that this wedge shape also applies to the central portion of the 9-km sill with potential for follow-up exploration.

“Our 2019 drilling at Colomac has changed how we view the deposit. The recent discovery of the sill’s dramatic widening of its mineralized portion to depth of up to 3 times its near-surface true width represents an incredible opportunity that may result in the exponential growth of tonnage and contained ounces,” Byron added.

Current inferred resources for the project stand at 50.3 million tonnes grading 1.62 g/t gold for 2.6 million ounces, contained within five deposits.

Colomac is a past-producing open pit with historical production of approximately 500,000 oz.
