Update on recent mining news in North Carolina
Brick maker to expand -- posted November 10, 2003 -- from the News and Observer, November 8, 2003.
Triangle Brick Co., a fast-growing clay brick manufacturer based in Durham, plans to invest $35 million in a new plant to be build in the Carolinas or Virginia. It is expected to employ 50 people and be the fifth brick plant the company operates by the time it opens.
Triangle Brick also plans to re-open a plant south of Durham that was closed a couple of years ago. That plant, which could be operating as early as January, will employ 35 people.
"The demand for brick overall continues to be strong, and we've had very strong demand for our products due to a number of our marketing efforts," said Scott Mollenkopf, Triangle Brick's vice president.
The company is not planning to locate its new plant in the Triangle, because it already has two plants in Merry Oaks south of Apex, he said.
Founded in 1959, Triangle Brick was sold in 1979 to Roeben Tonbaustaffe, a German manufacturer of tiles and brick. It is now a subsidiary of that company. The privately held company has seen sales triple in the past six years, Mollenkopf said.

Marathon and Exxon Mobil must be reimbursed for their leases for drilling off the North Carolina coast -- posted 1/5/01 -- from the News and Observer 1/3/01
The Interior Department must return $156 million to two oil companies because environmental restrictions prevented them from exploring for oil and natural gas off the North Carolina coast more than a decade ago.
A federal appeals court ordered payments to Marathon Oil Co., and Exxon Mobil Corp., saying the government had reneged on its contracts when it rescinded leases for drilling rights 45 miles east of Cape Hatteras on the Outer Banks.
The ruling issued by the U.S. Court of Appeals for the Federal Circuit directed the Interior Department to reimburse the two companies their full investment -- $78 million each -- and rejected government arguments that the payments should be reduced. The order requires interest to be paid at about 5 percent beginning December 29, 2000.
Hiddenite emerald bid - posted 12/15/2000 -- from the News and Observer 12/8/2000
A huge emerald unearthed two years ago near Stateville failed to sell at a New York auction on December 7, 2000. The 18.8 carat "Carolina Queen" is considered by many gem experts to be the rarest combination of size and quality every produced in the United States.
The rare stone drew a high bid of $460,000, which auction officials said was below the minimum they had set for the stone.
The stone was cut from a golf-ball-sized, 72-carat uncut crystal from an abandoned mine site located near Hiddenite, in Alexander County, NC in 1988. The same crystal had earlier produced another huge emerald called the "Carolina Prince," a 7.85 carat stone that was sold to a private buyer in 1999 for $500,000.
Corning plans to further expand Midland (NC) plant - posted 12/15/2000 -- from the News and Observer 12/8/2000
Corning announced 12/7/2000 that it will spend $450 million to expand its Cabarrus County fiber-optic cable plant, making it the largest such facility in the world.
The expansion follows a $550 million addition announced earlier this year and will add 475 jobs to the plant in Midland, which already employs 700 people. In all the company will add more than 1,000 employees when both expansions are completed sometime in late 20003 or 2004.
Corning's facility in Wilmington has been the world's largest optical-fiber plant.
Zemex to purchase ball clay and kaolin operations of Hecla Mining Co. - posted 12/15/2000
Zemex Corporation announced 11/20/2000 that it had agreed to purchase the ball clay and kaolin operations ("K-T Clay") of Hecla Mining Company for US$68 million, subject to closing adjustments. The acquisition, subject to regulatory approval is scheduled to close in January 2001 according to PRNewswire.
Hecla may sell industrial minerals subsidiary - posted 10/2/2000
Mining Engineering reported in its September 2000 issue (p. 30) that "Hecla Mining said it has received enough interest in its Kentucky-Tennessee (K-T Clay) industrial minerals subsidiary that the company is considering selling it."
According to Hecla, "...selling K-T Clay would allow Hecla to eliminate its bank debt and use the cash to take advantage of opportunities to increase the company's precious metals reserves and production."
Hecla acquired K-T Clay in 1984 when it merged with Ranchers Exploration and Development. K-T Clay is headquartered in Nashville, TN. It has ball clay, kaolin and feldspar operations in Tennessee, Kentucky, Georgia, North Carolina, South Carolina, Mississippi and Mexico. K-T provides about half of the nation's ball clay.

Winton (Hertford Co.) aluminum operation to be closed - posted 10/2/2000
According to the Associated Press in an article on September 27, 2000 in Raleigh's "News and Observer," the Winton (Hertford County) aluminum fabrication and extrusion operation operation will close. About 300 workers will be displaced. The operation is owned by Indalex. Indalex will transfer much of Winton's business to other plants, particularly the operation in Gainesville, GA.
The drawn tube operations at the Indalex plant in Winton will remain open. About 150 of the 450 plant employees work in the drawn-tube operations.
The plant's manufacturing and extrusion sector is being shuttered because the operation is aging and bringing "the plant up to an acceptable operational standard would be probative," said an Indalex spokesman.
The plan presses aluminum into various sizes, shapes and strengths for industrial uses.
Nucor is building a $300 million steel recycling plant in Winton that is expected to employ 300 workers.

Roofing granule operation announced - posted 1/30/2000
Minnesota Mining and Manufacturing (3M) plans a quarry on a 180-acre tract south of Pittsboro, N.C. The company's mining division uses the dark-colored rock to manufacture roofing granules, which in turn are used in the production of shingles. Core drilling continued into late 1999 and some additional core drilling was scheduled in early 2000. Permitting is in progress. (Note: Mining Permit #19-16 was issued March 27, 1999 by the Land Quality Section.)
Investment in a complete plant is estimated to be about $50 million. The facility is expected to be completed in 2002. 3M is reported to be eligible for job creation, worker training and investment tax credits as part of state incentives to attract industries. The roofing granules will be colored in neutral shades including blues, greens, blacks and browns.

Cherokee Sanford to be acquired - posted 1/30/2000; information updated through 5/4/2000
Cherokee Sanford Group LLC (Cherokee Sanford), the Sanford-based brickmaker, the state's largest, is being bought out by an Austrian company. Wienerberger Baustoffindustrie AG, the world's largest brickmaker, bought Cherokee Sanford for $US81 million through its U.S. subsidiary, Johnston City, Tennessee-based General Shale Building Materials GP, the parent company of General Shale Products LLC. The transaction was completed February 10, 2000.
Capacity at the Brickhaven (N.C.) plant is expected to expand. Wienerberger acquired General Shale in June 1999 for $260 million to gain a foothold in the U.S. market.
Wienerberger bought out local owner Thomas Darden; the Houston-based Rice, Sanglis, Toole and Wilson Investment Fund (owner of a 51 percent stake); and the equity held by Cherokee Sanford's top management. The current management team will be retained.
With five percent of the U.S. market, Cherokee Sanford is the sixth largest producer in the country, helped in large measure by North Carolina's role as the top-consuming brick state in the nation. Sales last year reached $81 million with an operating profit about $10 million. The leading brickmaker in the United States is Boreal Ltd. with a reported 18 percent market share.
The deal helps Wienerberger beef up its No. 2 position in the United States, pushing its market share up to 17 percent. Five of the top six brick producers in the United States are now foreign-owned.
Cherokee Sanford specializes in facing bricks, used in the facades of houses. Its five plants have a capacity of 375 million U.S.-brick units per year. Cherokee Sanford was formed when Cherokee Brick and Sanford Brick merged in 1984.

Alaskite and the geology of industrial minerals of the Spruce Pine District, North Carolina - posted 1/30/2000
Carl Merschat (Carl.Merschat@ncmail.net), Senior Geologist with the N.C. Geological Survey's Asheville Office (828-251-6208) presented an abstract at the 1998 SME Industrial Minerals technical program in Orlando, FL. A key conclusion of his presentation is that geologic mapping has delineated metasomatic schists surrounding granitoids that may represent potential mica, feldspar and quartz reserves.
In preparing his report, Merschat became aware that the ultra-high purity quartz produced in the Spruce Pine Mining District is not included in the USGS Mineral Industry Survey of North Carolina. It may not be included because it is considered a manufactured product. Unimin is known to produce a quartz product from their Schoolhouse Quartz plant and mine located along Brushy Creek in Avery County. It can be estimated that as much as $200 million of ultra-pure quartz may be produced annually. If true, the value of this high-dollar material is considerable and would improve North Carolina's rank and standing in industrial mineral production in the United States.
Merschat noted in his abstract that "The Spruce Pine Mining District, northwestern N.C., produces more than $75 million worth of feldspar, scrap mica, ultra-pure quartz, and olivine annually, and is a leading U.S. producer in most. Sheet mica, residual kaolin, anthophyllite, and kyanite were previously mined in the district. Feldspar, mica, and ultra-pure quartz are derived from Devonian peraluminous granodioritic to quartz dioritic plutons (uniquely low in iron and titanium) that intruded Late Proterozoic metasediments and metavolcanics. Dunites, emplaced into Late Proterozoic sequences and Grenville basement rocks, yield olivine."
Potash Corporation of Saskatchewan, Inc. (PCS) - posted 5/5/2000
According to the 1999 PCS annual report (p.33), PCS is "...proceeding with a consolidation of its Raleigh, NC and Memphis, TN administrative offices with the Company's office in Chicago, IL. As a result of the consolidation, 115 salaried employees will be terminated, with termination dates ranging from March 31, 2000 through to September 30, 2000." The report did not state the exact number of positions that would be lost from the Raleigh, NC area.
The same report (p. 11) stated "With the idling of the PCS export terminal at Jacksonville, Florida, White Springs (Florida) now exports through the port facility at Morehead City, North Carolina used by Aurora. This consolidation helped reduce distribution costs and improve services."
Zemex Corporation - posted May 5, 2000
