JOHANNESBURG (miningweekly.com) With the Tongon gold mine, in Cte dIvoire, operating to plan, West Africa-focused gold miner Randgold Resources has shifted its focus to the discovery of additional reserves and resources.

Tongon continued to ramp up production, tracking the 2017 output target of 285 000 oz of gold, CEO Mark Bristow said in a statement on Monday.

In line with this, the company is seeking to replace depleted ounces and extend the mines life beyond its current four-year horizon.

Bristow previously highlighted the high resource potential of the exploration programme at Tongon.

Meanwhile, with eyes on what Bristow described as potentially the most exciting gold prospect in West Africa, the companys exploration programmes have defined a large target at Boundiali in the Fonondara corridor.

The company has just completed its yearly review of its exploration targets . . . [which also] highlighted very positive results from its other holdings in the country, underlining again Cte dIvoires exceptional prospectivity, Bristow said.

Wayne Gooden holding up a photo of his time in the service.

Editors note: The Journals Unsung Heroes series spotlights a local veteran each week from Memorial Day to Veterans Day. If you would like to nominate an Unsung Hero, email news@journal-news.net.

MARTINSBURG Wayne Gooden, 75, is a decorated Vietnam War Veteran with a colorful military history and police background.

Gooden said he remembers his time in the service vividly, entering the military at age 19.

I went into the military at such a young age, Gooden said.

I actually wanted to travel a bit before I went in, but then I just decided to stay in and serve. In 1967, I was sent to Vietnam and once I got there, I was assigned to the food service. After I was there about three months, I decided I wanted to go into combat arms, which was an infantry unit. I served with the infantry unit for about four months. They sent me back to the NCO Academy (Non-commissioned Officer Academy) and once I graduated from there, I heard that they were looking for volunteers for LERPS (Life Extension Refurbishment Program). The LERP is a four-man recon unit and I was with the 4th Brigade, 2nd Infantry Division LERPS. It was a volunteer thing, one assignment and you can quit at any time.

Gooden was awarded the Bronze Star medal for heroism on March 24, 1968 from his commanding officer Charles R. Swiffin, Colonel, GS-Chief of Staff.

I was awarded the Bronze Star award for heroism in connection with military operations against an armed hostile force in the Republic of Vietnam, Gooden said.

Gooden was participating in a long range enemy reconnaissance patrol when the men observed an enemy platoon moving toward their position.

Knowing that contact with the numerically superior enemy force was unavoidable, the team leader deployed his men to the most advantageous positions, assigning Sgt. Gooden with the responsibility of rear security, said Col. Swiffin in a letter recognizing Gooden for his heroic efforts. Throughout the ensuing engagement, Sgt. Gooden prevented enemy soldiers from breaking through his area of responsibility. When a fellow soldiers weapon malfunctioned, Sgt. Gooden gave the man his own rifle. Courageously, he continued to hold his position, using hand grenades against the threatening enemy. Largely through his heroic efforts, the four Americans effectively repelled the enemy platoon. Sgt. Goodens personal bravery and exemplary devotion to duty are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.

Gooden said he is very proud of his military service.

When I served my first tour over there in 68 everyone knows that was a bad year but I served it proudly, Gooden said. The only way we got out was because of the chopper. It was literally pulling each of us up by our arms. After that, I went back home for a bit, then went to Fort Leonard Wood in Missouri to start training. It was there I decided I wanted to go back to Vietnam, so I asked my commanding officer if I could return and I did. On my second tour, I was assigned to a security outfit and then after four months I decided I wanted to go into law enforcement.

Gooden was then assigned to the U.S. Army Criminal Investigation Command Office as a military police investigator.

I served my tour there, stationed at Fort Bragg, North Carolina, Gooden said. I decided to go back to Vietnam a third and final time to the same CID office. After I finished my tour there, I was awarded the Army Commendation medal twice, for involvement with solving drug cases, things like that. Then I went back to the states for a while. That time I was assigned to the military police school in Fort Gordon, Georgia. I was assigned there because they came up with a formal class for the military police investigators, and I was chosen to help write the first lesson plan for that class.

From there, Gooden went to complete a tour in Germany, and from there he landed at Fort Knox, Kentucky. Gooden then found himself in San Juan, Puerto Rico.

I was assigned there as a military police investigator, Gooden said. So I finally got to do my traveling that I have always wanted, just in a different capacity.

Gooden then came close to home.

I was lucky enough to get close to Martinsburg, where I was assigned to Fort Ritchie, Maryland, to the Post Marshals office, Gooden said. There I was a crime prevention officer, a physical security investigator and court liaison officer.

Gooden stayed there until 1981 when he retired.

After staying out 10 years, Gooden decided he wanted back in.

He went to the federal law enforcement academy in Brunswick, Georgia, and was assigned to the Pentagon as a federal police officer and then earned a spot on the protective service detail agency within the U.S. Department of Defense, where he stayed until 2004 when a vehicle accident forced him to retire.

When I was working at the Pentagon, I enjoyed my time on the protective service detail and all aspects really. I met a lot of amazing people and formed great relationships, Gooden said.

Now that Gooden has officially retired, he said he has no plans of slowing down.

Gooden said he plans to take many vacations with his wife and children, but he also has more exciting projects for this upcoming year.

Gooden has a love for gospel music.

According to Gooden, he has recorded two gospel albums already and hopes to record his third, to be released next fall.

I have always had a passion for writing and performing gospel music, Gooden said. I am currently recording for my third album and I am happy I finally have the time to really pursue my music.

Gooden said he is also working on writing a book about his life.

The book will be called God and Country,' Gooden said. I hope to have that out within the next year or two.

Looking back, Gooden remembers his military service fondly.

To me, I have had a great career and I am grateful for the career that I have had, Gooden said. I am not saying all of it was easy, but I truly gave my life to this, I gave the federal government 33 and a half great years and I just cant wait for my next adventure.

Local veteran shares colorful past - Martinsburg Journal

The United Kingdom did more than any nation to pioneer armored warfare, and its Challenger 2 stands amongst the best tanks in the world. The sixty-two-ton tank established a reputation for exceptional toughness during combat in Iraq. But despite being a newer design than the Leopard or Abrams, the Challenger 2 has not been lavished with the extensive upgrades that its NATO peers have, and is generally perceived as having fallen behind.

In January 2017, the Ministry of Defense declared it had short-listed competing proposals from BAE Systems and German Rheinmetall for a modest Challenger 2 Life Extension Program (LEP) to improve the vehicles sensors and fire control computers. While the LEP is meant to increase the Challenger 2s service life until 2035, neither proposal addresses the most glaring issues with the vehicle.

The Challenger 2 entered service only fifteen years after the Challenger 1 in 1983. At the time, it was the first British tank to benefit from state-of-the-art Chobham composite armor, which decisively restored the defensive primacy of modern tanks. However, the Challenger 1 still shared many systems with the preceding Chieftain tank, including a sluggish fire control system. The new tank performed poorly in exercises and suffered from extravagant teething issues. The Ministry of Defense was inspired to sign on to a more thoroughly modernized design in 1989.

Ironically, the Challenger 1 performed brilliantly under actual combat conditions in the Gulf War, destroying 200 to 300 Iraqi tanks without suffering any losses. The Challenger and Abrams were simply more than the Iraqis could handle. The Iraqi army was fielding older Soviet tanks that could not defeat such formidable armorthey might have had a fighting chance if they had improved ammunition. In return, the 120 millimeter guns on both vehicles could effortlessly pierce opposing armor. A Challenger 1 crew even achieved a record long-range shot during the conflict, destroying an Iraqi tank from 3.2 miles away.

But the Challenger replacement was already well underway. Despite its similar appearance, the Challenger 2 that entered service in 1998 had very few parts in common with its predecessor. It featured a longer barrel L30A1 cannon with a longer fifty-five-caliber barrel, and an upgraded composite package known as Dorchester armor, mixed with extra Explosive Reactive Armor (ERA) tiles. The latter type of armor involves metal plates sandwiched with explosives that explode outward against incoming projectiles, diminishing or deflecting the blast of shaped-charge warheads. In addition to the main gun, the crew of four can fire machineguns.

The Leopard 2, Abrams and Challenger are all considered to be broadly similar in capability, but the British design has some distinguishing quirksnotably, it was formerly considered the best armored of the three tanks, but also the slowest with a maximum speed of thirty-seven miles per hour. This latter trait is related to its underpowered 1,200 horsepower engine, compared to 1,500 horsepower powertrains on other top Western tanks.

The Challenger 2 is also noted for being one of the only modern tank design in its weight class to use a rifled gun. A rifled gun allows for greater accuracy, but the spinning motion it imparts leads to lower muzzle velocity, diminishing penetrating power for the kinetic armor-piercing sabot shells favored by most countrieswhich are quite stable anyway. But British tankers in the 1980s were more interested in their own unique form of ammunition, the High Explosive Squash-Head (HESH) which does not depend on kinetic energy for penetration, but still could benefit from the greater accuracy of a rifled barrel. HESH rounds employ a plastic explosive that generates a shock to the interior vehicle, causing metal to spall.

The Challenger 2 soldiered on in the U.S. invasion of Iraq in 2003, where it once again steamrolled opposing tanks around the city of Basra without suffering any losses to hostile fire. The British tank faced the greatest danger from roadside bombs and rocket-propelled grenades. One Challenger 2 was allegedly struck by seventy RPGsand emerged with its crew unscratched. Another survived seventeen RPGs and a Milan missile, and despite the battle damage, was back in combat the next day.

The Challenger 2s reputation for indomitability created somewhat unreasonable expectations. In 2007, it was revealed that a few years back an insurgent using an RPG-29an especially powerful 105 millimeter warheadhad pierced through the belly armor of a Challenger 2 as it crested a dune. The belly armor is one of the weakest points on any tank. The penetrating warhead mauled the drivers footthough the vehicle remained in operational condition and was able to back away from the ambush. Another Challenger 2 was disabled in 2007 by an IED, but restored into operational condition. The only Challenger 2 to be totally destroyed was hit by another Challenger 2 tank by accident.

The Ministry of Defense was lambasted for having tanks that were not actually indestructible, and slightly more reasonably, that they had covered up the initial incident. Afterwards, the ERA armor on the lower front-hull was replaced with heavier Dorchester composite armor. Presently, the armor packages on the Challengers 2 breaks the scales at around seventy-five tons!

Would you spend a rupee if it saved you Rs 677? Eagerly, perhaps. The US Department of Defense has been saving billions of dollars for 30 years by continuing to use 'expired' medicines in its stock after testing them. Last year, the tests--part of its Shelf Life Extension Program--cost $3.1 million and saved $2.1 billion. Are drugs safe to use past their 'expiry' date? If they are, why do they come printed with expiry dates only 2-3 years from the date of manufacture? A recent article on ProPublica 'That Drug Expiration Date May Be More Myth Than Fact' shows why drug companies ought to revise their expiry schedules.

When Lee Cantrell, a toxicologist who helps run the California Poison Control System, and Roy Gerona, a University of California, San Francisco researcher who specialises in analysing chemicals, started testing leftover stocks of pills from the 1960s, they were surprised to find that "a dozen of the 14 compounds were still as potent as they were when they were manufactured, some at almost 100% of their labeled concentrations."

Have we been 'expiring' perfectly good drugs? - Times of India

July 24, 2017 07:30 ET | Source: Mandalay Resources Corporation

TORONTO, July 24, 2017 (GLOBE NEWSWIRE) -- Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX:MND) is pleased to provide exploration updates for the first half of 2017 for two of its producing properties, Bjrkdal (Sweden) and Costerfield (Australia), and its Challacollo (Chile) development project.

This press release refers to tables and figures. Accompanying tables can be found at the end of this press release, whereas the figures accompanying this release can be found in an exploration presentation posted on the Companys website that can be accessed at:

http://www.mandalayresources.com/investor-presentations/#Technical_Presentations

Dr. Mark Sander, President and CEO of Mandalay, commented, In the first half of 2017, our exploration programs yielded excellent results, which clearly demonstrate the potential for significant near-term and long-term Mineral Reserve additions at both Bjrkdal and Costerfield.

At Bjrkdal, extensional drilling to the northeast and north of the mine demonstrated that the gold mineralized system extends several hundred metres beyond the current mine in those directions and is not yet closed off. As a result, we have demonstrated the potential to increase Mineral Reserves at Lake Zone underground and West Pit at surface. We have also made significant progress in understanding the distribution and characteristics of high-grade skarn mineralization that occurs both in the open pit and underground mines. Follow-up drilling is planned.

At Costerfield, drilling has improved the outlook for mine life extensions at different scales. At Brunswick, new holes have delivered high-grade, deep intersections that are expected to make a positive impact on the updated Mineral Resource and Reserve model anticipated in the fourth quarter. As previously reported, we anticipate the new model will significantly extend mine life based on our expectation that Brunswick will prove to be economic. As well, the potential next major new mineralized shoot after Brunswick has begun to emerge in our new drilling below the historic workings on the main Costerfield lode. These intercepts contain extraordinary gold and antimony grades scattered along a 400 metre strike length and 100 metre vertical interval. New intercepts along N-lode have also identified new splays which, as we follow them up, have the potential for incrementally adding Reserves near current underground infrastructure.

Dr. Sander concluded, Lastly, at Challacollo, we reached a major milestone with the discovery of sufficient water to support an eventual operation. Activities to permit and complete a production well, followed by transfer of existing water rights to the new location are underway. We now have the option to launch a project to optimize previously estimated capital and operating costs for a mine and plant at Challacollo.

Bjrkdal Exploration

Significant Exploration Results (Tables 1 through 4; Figures 1 through 5)

Underground Exploration

In the first half of 2017, underground diamond drilling at Bjrkdal extended the north-eastern limit of the Bjrkdal vein-system and infilled discrete areas. Intercepts from the extensional drilling demonstrate that gold mineralization extends along-strike from the defined resource for at least 200-300 metres (Figure 2 and Table 2) and mineralization remains open to the north and east. Infill drilling also increased confidence and delivered some high-grade intercepts in areas closer to the current limits of the mine (Figure 3 and Table 3).

Open Pit Exploration

Near-mine surface drilling with both core and Reverse Circulation methods during the first half of 2017 focused on extending gold mineralization in the north-western portions of the West Pit (Figure 4). This drilling intercepted many new mineralized intervals in the northern wall of the West Pit (Table 4). Results from this extensional drilling demonstrate that the mineralized vein-system in this area of the deposit extends from the current limits of the West Pit to at least 150 m further to the north. These veins are interpreted to correlate with the same vein-system mined from the underground mine, located to the east of this area. Therefore, the Bjrkdal vein-system remains open to the west and north-west of the current mine footprint, presenting high-calibre extensional targets for future exploration programs at Bjrkdal.

In addition to successful extensional drilling of the Bjrkdal vein-system, significant gold intercepts were also obtained from non-veined, mineralized carbonate lenses belonging to the host-stratigraphy (the Bjrkdal marble unit). These mineralized carbonate lenses are strongly altered, containing abundant amphiboles (predominately actinolite), silica and chlorite with accessory pyrite, pyrrhotite and pyroxenes. This metasomatic assemblage suggests skarn-like depositional mechanisms, and represents an exciting new deposit-type both within and peripheral to the footprint of the current Bjrkdal mine.

Three gold-bearing, skarn-like bodies have been defined though drilling over the past six months; two in the vicinity of the underground mine and a single in the open pit mine (Figure 5). The skarnified carbonate lenses are shallow dipping, narrow, plunging bodies that are located above and adjacent to the Bjrkdal vein-system. Intercepts of this skarn-hosted gold-mineralization include:

These results suggest that this style of mineralization presents the possibility of bulk-minable tonnages of potentially much higher gold-concentrations than the more typical Bjrkdal vein systems. Within the month of June, a 1,176 tonne parcel of the recently exposed West Pit skarn ore was crushed and milled with results indicating a back-calculated head-grade of 4.30 g/t Au. The recent intercepts of all significant gold-bearing skarn intercepts will be followed up as priority targets in the remainder of 2017 and 2018 exploration programs, while regional exploration models and programs will be refined to incorporate further targeting of near-surface, high-grade gold skarn and skarn-like mineralized systems in the larger Bjrkdal area.

Bjrkdal Drilling, Sampling and Assaying

During the period from January 1, 2017 to June 30, 2017, a total of 13,640 metres of exploration drilling was completed in 66 drill holes. Drilling included 23 surface core and RC holes totalling 3,451 m and 43 underground core holes totalling 10,189 m. All drill-hole collars are surveyed, and downhole surveys are completed in order to record hole azimuth and dip variations.

All surface and underground exploration drilling has been conducted by third party contractors, with a mix of core and reverse circulation drilling using WL66, NQ2, HQ and 5 RC sized drilling equipment (producing 50 mm, 50.5 mm and 63.5 mm diameter core respectively).

Core and RC samples are logged by Mandalay geologists on-site. Assaying of Bjrkdal samples was completed at CRS Minlab Oy (CRS) in Kempele, Finland and ALS in Pite, Sweden. Whole core samples (WL66 and NQ2 size) were sent directly to the independent laboratories for sample preparation and assaying, while HQ diameter core was half-sawn at the laboratories off-site before sample preparation. Assaying was conducted utilizing the Pal1000 (CRS) and LeachWELL (ALS) cyanide leaching processes. Mandalays rigorous QA/QC program includes the use of standard reference samples, blanks, duplicates, repeats, and internal laboratory quality assurance procedures. More details on the drilling, logging, sampling, and assaying procedures are contained in the Technical Report Mandalay Resources Corporation Technical Report on the Bjrkdal Gold Mine, Sweden filed on SEDAR (www.sedar.com) on January 27, 2017.

Costerfield Exploration

Significant Exploration Results (Tables 5 through 8; Figures 6 through 12)

Brunswick Following structural analysis of Brunswick mineralization, the Company conducted infill drilling within the Penguin to Kiwi (PK) panel of the Brunswick lode (Table 6 and Figure 7). Further confidence of grade continuity was gained through this drilling, with high-grade intercepts including 24.4 g/t Au and 6.1% Sb over a vein width of 2.01 m in BD278W2.

These results will be reflected in a resource update expected in the fourth quarter of 2017. This drilling is expected to result in an increase in Indicated Mineral Resource of the Brunswick lode.

Further drilling was undertaken with the purpose of extending Brunswick below the Kiwi Fault and to the south. Both drilling campaigns intercepted antimony and gold mineralization along the Brunswick corridor. Mineralization has now been identified approximately 280 m below historic workings and approximately 100 m below the current Inferred Mineral Resource. Below the historic B3 pit, the Brunswick line of mineralization has been identified at a depth of 225 m below surface and over a strike length of 300 m (Figure 7). Highlights of this extension drilling are:

Future exploration efforts are expected to focus on extending the current Mineral Resource below the Kiwi fault and into Brunswick South, pending economic analysis.

Costerfield

A target testing campaign investigating the continuation of mineralization underneath the historic Costerfield mine workings is currently underway. The early stages of this campaign have shown great success with mineralization confirmed over a strike length of approximately 500 m and to a depth of approximately 150 m vertically below the current workings (Figure 8). The highlight of the program during the first half of 2017 is the deepest northern intercept, which contained 59.8 g/t Au and 3.2% Sb over a true vein width of 0.56 m in BC006w1 (Table 7).

N Lode Upper

Structural analysis of the mineralized corridor known as N Lode has led to the recognition of a previously untested prospective zone near to surface. The first drill hole to test this area has confirmed the presence of an up-dip continuity to the enriched northern portion of N Lode. The proximity of this mineralization to established underground development makes this find an important focus for near future delineation drilling (Table 8 and Figure 9).

Alison South

Testing of the upper portion of mineralization over the Cuffley Deposit has returned high-grade gold results within two veins in an offset, up-dip continuation of the Cuffley Deposit named Alison South. The highlight of this drilling was an intercept containing 71.1 g/t Au and 0.5% Sb over a true vein width of 0.35 m in AD168 (Table 8 and Figure 10).

K Lode

A high-grade portion of K Lode was discovered through the opportunistic drilling program (Table 8 and Figure 11). This vein has already been accessed through mining on an intersecting portion of N Lode which makes this a potential low-cost mining source in the near future.

Augusta East

A drilling campaign investigating the possibility of an eastern repetition of the Augusta and Cuffley line of mineralization is currently underway. Gold has been located within a near-surface, sub-vertical vein set in the first hole to be drilled on this target (Figure 12). Although the grade of these intercepts are not potentially economic, they are characteristic of the periphery of orebodies in the district. Follow-up drilling is planned.

Costerfield Drilling, Sampling, and Assaying

During the first half of 2017, Mandalay drilled 18,489 m of diamond core at its Costerfield gold-antimony mine (Table 5). 5,520 m was dedicated to increasing immediate mine life through infill and extension of the Brunswick resource and through opportunistic drilling projects on K Lode, N Lode and Alison South. 12,969 m was devoted to regional exploration, with the drill testing of the Costerfield Mine extension, Augusta East and Brunswick line of lode extension. In addition, the Company completed 1,652 m of on-vein operating development and associated sampling of N Lode, Cuffley Lode, New Vein, Bob lode and associated splays.

Drill core was logged and sampled by Costerfield geologists, who also mapped and sampled the development advances. All samples were sent to Onsite Laboratory in Bendigo, Victoria, Australia for sample preparation and assay. Site geological and metallurgical personnel have implemented a QA/QC process that includes the regular submission of standard reference materials and blanks with drill and face samples submitted for assay. Standard reference materials have been certified by Geostats Pty Ltd. (see Technical Report entitled Costerfield Operation, Victoria, Australia NI 43-101 Report, filed on SEDAR (www.sedar.com) March 31, 2017, which contains a complete description of drilling, sampling, and assaying procedures).

Challacollo Exploration

Four holes were drilled at Challocollo during the first half of 2017 to explore for water, a critical requirement for further project development. A total of 416.5 metres was drilled, with all four holes encountering promising quantities of water. Drill hole locations are provided in Figure 13, with pump test results in Table 9.
