Brigus reports 49% increase in Gold production output and 40% reduction in "all in" costs of production

Brigus Gold Reports Third Quarter Financial Results 

Brigus Gold Corp. ("Brigus" or the "Company") (NYSE MKT: BRD) (TSX: BRD)
 today reported financial results for the third quarter ended September 30, 2013.

"Brigus delivered strong operating and financial results during quarter three. The Black Fox mine achieved record gold production while costs on a per ounce basis were at an all-time low, and lower than guidance.Moving forward, our top priorities continue to be safe production, cost management, and disciplined capital allocation," commented Wade Dawe, Brigus' Chairman and Chief Executive Officer. "I am proud of our team's operational performance and the fact that our workforce has worked over 1,400 days without a lost time incident."

Third Quarter 2013 Financial Highlights
-- Sold 28,344 ounces of gold, a 49% increase over Q3 2012
-- Cash costs of $617 and All in Sustaining Costs (AISC) of $992 per ounce of gold sold (40% reduction)
-- Made long-term debt repayments of $4.9 million
-- Revenue of $36.9 million, a 22% increase over Q3 2012
-- Adjusted cash flow from operations of $15.5 million, a 38% increase over Q3 2012
Third Quarter 2013 Operational Highlights
-- Produced 27,174 ounces of gold, a 39% increase over Q3 2012
-- Processed 207,559 tonnes of ore (2,256 tonnes per day) at 4.34 grams per tonne and a 94% recovery
-- Averaged 811 tonnes per day from underground at an average grade of 5.69 grams per tonne


During the third quarter of 2013, income from mining operations was $5.9 million. AISC per ounce for the third quarter was $992 per ounce, compared to $1,649 in the third quarter of 2012, a decline of $657 or 40%. Cash costs per ounce decreased by 15% from $728 per ounce in Q3 2012 to $617 per ounce in Q3 2013.
During the quarter the Company's cash balance increased to $21.1 million, compared to $20.9 million at the end of the previous quarter, while the balance sheet was strengthened as long term debt was reduced. Income from mining operations on a year-to-date basis totalled $18.8 million, an increase of $4.7 million compared to the same period in 2012.The increase relates to the 47% increase in ounces sold and an 11% decrease in cash costs, offset by a 10% decrease in the average realized gold price and 58% increase in depreciation and amortization expense. 

Total liabilities decreased by $23.7 million, from $188.7 million as of December 31, 2012, to $165.0 million as of September 30, 2013, and shareholders' equity increased from $232.6 million to $243.8 million year to date.
Cost management continues to be a key focus for the Company.The Company expects capital spending for mine development and other sustaining capital to total $38.5 million in 2013, down from the original estimate of $41.5 million in Q1 2013. The Company reviewed its long-term capital requirements and is forecasting total capital spending on mine development and sustaining capital of $20 - $25 million in 2014.
During the quarter, the Company announced an updated independent NI 43-101 resource estimate for the 147, Contact, and Grey Fox South zones. The resource estimate included a constraining pit shell which had not been included in the previous resource estimates.Highlights include a total of 507,400 indicated ounces (255,000 relating to the underground and 252,400 relating to the open pit) and 228,600 inferred ounces (184,800 relating to the underground and 43,800 relating to the open pit). The underground and open pit cut-off grades were set at 2.84 grams per tonne and 0.72 grams per tonne, respectively. The 147, Contact and Grey Fox South zones remain open for future expansion and drilling continues.
At Grey Fox, Brigus completed an additional 21,458 metres (46 drill holes) of drilling since the June 30th cut-off date and initiated additional metallurgical studies to increase gold recoveries from the 83 percent threshold, as previously reported. Initial results from the ongoing test work have been favourable. The Company is now planning to release a Preliminary Economic Assessment for Grey Fox during the second quarter of 2014.
Exploration Subsequent to quarter end, the Company released two high grade gold intersections from underground drilling at Black Fox. Hole 645-34-W assayed 18.09 grams per tonne gold over 37.80 metres, including 39.45 grams per tonne gold over 10.35 metres. This 37.80 metre mineralized intercept is from a drill interval of 316.9 to 354.7 metres, and remains open as the last sample at 354.7 metres graded 15.34 grams per tonne gold. Therefore, the full thickness of this high grade intercept is unknown at this time. Hole 645-34-W intersected high grade mineralization 30 metres to the west of hole 645-01-W, which assayed 40.71 grams per tonne gold over 26.75 metres, including 103.20 grams per tonne gold over 8.35 metres.In light of these positive exploration results, we have recommenced underground exploration drilling at Black Fox. 12 to 15 holes are planned and will target this new high grade zone.

Brigus Gold Drills Deepest High Grade Intersection to Date at Grey Fox

 May 2013 by Business Wire Brigus Gold Corp. ("Brigus" or the "Company") (NYSE MKT: BRD; TSX: BRD) is pleased to report additional results from its ongoing drill program at the 147 Zone on the Grey Fox property. Results from this drill program will increase the current gold resource and further confirm the potential for both a new open pit and underground mine. The Grey Fox property is located approximately four kilometres southeast of Brigus' Black Fox mine and boasts excellent infrastructure. Due to the close proximity of Grey Fox to the Black Fox mine, the Company sees potential for near term production growth.

"These impressive results further extend the 147 Zone orebody and it remains open for expansion at depths beyond 400 metres vertical," said Howard Bird, Brigus' Senior Vice President of Exploration. "Four drill rigs will continue resource expansion drilling on the 147, Contact and Grey Fox South zones for the remainder of the year."
The Company plans to release an updated NI 43-101 resource estimate for the Grey Fox property later in the quarter.
Highlights from the 147 Zone which remains open for expansion:

Brigus Gold reports more high grade drilling results at new Grey Fox site!

Company News Alert
High Grade Drilling Results to Expand the Resource at Grey Fox (bwire)

HALIFAX, Nova Scotia (Business Wire) -- Brigus Gold Corp. (“Brigus” or the “Company”) (NYSE MKT: BRD; TSX: BRD) is pleased to report additional drilling results from its ongoing drill program at the 147 Zone, including high grade gold intercepts of 8.7 grams per tonne over 21 metres and 6.2 grams per tonne over 25 metres. 

“It is clear that the Grey Fox resource is more significant than initially reported,” said Howard Bird, Brigus' Senior Vice President of Exploration. “These high grade drill results are located outside of our current resource estimate and will expand the gold resource on the Grey Fox property.” 

Next quarter, the Company plans to release an updated NI 43-101 resource estimate on the Grey Fox property followed by a full feasibility study in Q3 2013.

“Currently we have four drill rigs turning on the 147 Zone and one rig on the Contact Zone,” said Bird. “Drill results are demonstrating excellent potential for both an open pit and underground mine on the Grey Fox property.”
Brigus' 2013 Grey Fox drilling program is designed to extend and expand both the 147 and Contact zones through systematic drilling along strike and below the 200m level. Recent drilling results from below the 200m level prove strong continuity in the down-dip especially with hole GF12-639 intersecting 5.35 grams per tonne gold over 11 metres at a vertical depth of 380 metres below surface.

Graphene micro super capacitors will change the world according to UCLA Prof

University of California - Los Angeles

UCLA researchers develop new technique to scale up production of graphene micro-supercapacitors

While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors.

Now, Richard Kaner, a member of the California NanoSystems Institute at UCLA and a professor of chemistry and biochemistry, and Maher El-Kady, a graduate student in Kaner's laboratory, may have changed the game.

The UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom–thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.

The new cost-effective fabrication method, described in a study published this week in the journal Nature Communications, holds promise for the mass production of these supercapacitors, which have the potential to transform electronics and other fields.

"The integration of energy-storage units with electronic circuits is challenging and often limits the miniaturization of the entire system," said Kaner, who is also a professor of materials science and engineering at UCLA's Henry Samueli School of Engineering and Applied Science. "This is because the necessary energy-storage components scale down poorly in size and are not well suited to the planar geometries of most integrated fabrication processes."

"Traditional methods for the fabrication of micro-supercapacitors involve labor-intensive lithographic techniques that have proven difficult for building cost-effective devices, thus limiting their commercial application," El-Kady said. "Instead, we used a consumer-grade LightScribe DVD burner to produce graphene micro-supercapacitors over large areas at a fraction of the cost of traditional devices. Using this technique, we have been able to produce more than 100 micro-supercapacitors on a single disc in less than 30 minutes, using inexpensive materials."

The process of miniaturization often relies on flattening technology, making devices thinner and more like a geometric plane that has only two dimensions. In developing their new micro-supercapacitor, Kaner and El-Kady used a two-dimensional sheet of carbon, known as graphene, which only has the thickness of a single atom in the third dimension.

Kaner and El-Kady took advantage of a new structural design during the fabrication. For any supercapacitor to be effective, two separated electrodes have to be positioned so that the available surface area between them is maximized. This allows the supercapacitor to store a greater charge. A previous design stacked the layers of graphene serving as electrodes, like the slices of bread on a sandwich. While this design was functional, however, it was not compatible with integrated circuits.

In their new design, the researchers placed the electrodes side by side using an interdigitated pattern, akin to interwoven fingers. This helped to maximize the accessible surface area available for each of the two electrodes while also reducing the path over which ions in the electrolyte would need to diffuse. As a result, the new supercapacitors have more charge capacity and rate capability than their stacked counterparts.
 Interestingly, the researchers found that by placing more electrodes per unit area, they boosted the micro-supercapacitor's ability to store even more charge.

Kaner and El-Kady were able to fabricate these intricate supercapacitors using an affordable and scalable technique that they had developed earlier. They glued a layer of plastic onto the surface of a DVD and then coated the plastic with a layer of graphite oxide. Then, they simply inserted the coated disc into a commercially available LightScribe optical drive — traditionally used to label DVDs — and took advantage of the drive's own laser to create the interdigitated pattern. The laser scribing is so precise that none of the "interwoven fingers" touch each other, which would short-circuit the supercapacitor.

"To label discs using LightScribe, the surface of the disc is coated with a reactive dye that changes color on exposure to the laser light. Instead of printing on this specialized coating, our approach is to coat the disc with a film of graphite oxide, which then can be directly printed on," Kaner said. "We previously found an unusual photo-thermal effect in which graphite oxide absorbs the laser light and is converted into graphene in a similar fashion to the commercial LightScribe process. With the precision of the laser, the drive renders the computer-designed pattern onto the graphite oxide film to produce the desired graphene circuits."

"The process is straightforward, cost-effective and can be done at home," El-Kady said. "One only needs a DVD burner and graphite oxide dispersion in water, which is commercially available at a moderate cost."
The new micro-supercapacitors are also highly bendable and twistable, making them potentially useful as energy-storage devices in flexible electronics like roll-up displays and TVs, e-paper, and even wearable electronics.

The researchers showed the utility of their new laser-scribed graphene micro-supercapacitor in an all-solid form, which would enable any new device incorporating them to be more easily shaped and flexible. The micro-supercapacitors can also be fabricated directly on a chip using the same technique, making them highly useful for integration into micro-electromechanical systems (MEMS) or complementary metal-oxide-semiconductors (CMOS).

These micro-supercapacitors show excellent cycling stability, an important advantage over micro-batteries, which have shorter lifespans and which could pose a major problem when embedded in permanent structures — such as biomedical implants, active radio-frequency identification tags and embedded micro-sensors — for which no maintenance or replacement is possible.

As they can be directly integrated on-chip, these micro-supercapacitors may help to better extract energy from solar, mechanical and thermal sources and thus make more efficient self-powered systems. They could also be fabricated on the backside of solar cells in both portable devices and rooftop installations to store power generated during the day for use after sundown, helping to provide electricity around the clock when connection to the grid is not possible.

"We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors," Kaner said

Brigus Gold Intersects more High Grade gold deposits at 147 Zone

 (bwire)
HALIFAX, Nova Scotia (Business Wire) -- Brigus Gold Corp. (“Brigus” or the “Company”) (NYSE Amex: BRD; TSX: BRD) reports that results from its ongoing drilling program at the 147 Zone on its Grey Fox property in the Gold District of Timmins, Ontario, Canada, include high grade intercepts of 14 grams per tonne over 35 metres and 4.7 grams over 29 metres. 

Brigus Senior Vice President Exploration Howard Bird said, “These impressive drill hole intercepts are among the best returned from the 147 Zone. These results extend the ore body to a true vertical depth of 300 metres below surface and most importantly the zone remains open for further expansion.” 

Highlights from the 147 Zone drill holes reported today (all assays capped at 100 gpt gold, average gold grades over core length widths) include:

These drill holes will add to the September 2012 resource estimate of 480,850 Indicated ounces and 91,061 Inferred ounces for the 147 and Contact zones. Approximately 84 percent of the drill data used to compile the September 2012 resource estimate was within 200m of surface demonstrating excellent open pit mining potential.

In 2013 Brigus will extend and expand both the 147 and Contact zones through systematic drilling below the 200m level and along strike. Bird said, “Today's results further demonstrate the excellent potential for significant resource additions.” 

The 147, Contact and Grey Fox South zones are located on the Company's Grey Fox property on the southern portion of the Black Fox Complex. Planning is underway to develop this property into the Company's next mine. A full feasibility study on the Grey Fox property will be released during the second half of 2013. Brigus plans to commence production in early 2015.
