Going for gold

Geoff Manaugh

1. In a 2011 paper on the medical effects of scurvy, author Jason C. Anthony offers a remarkable detail about human bodies and the long-term presence of wounds. “Without vitamin C,” Anthony writes, “we cannot produce collagen, an essential component of bones, cartilage, tendons and other connective tissues. Collagen binds our wounds, but that binding is replaced continually throughout our lives. Thus in advanced scurvy”—reached when the body has gone too long without vitamin C—“old wounds long thought healed will magically, painfully reappear.”^[1]

In a sense, there is no such thing as healing. From paper cuts to surgical scars, our bodies are catalogues of wounds: imperfectly locked doors quietly waiting, sooner or later, to spring back open.

2. The Carlin Trend was discovered in north-central Nevada, near the town of Elko, in 1962. Some fifty years later, at this time of writing, it remains one of the world’s largest actively mined deposits of gold ore. In fact, the region has become something of a category-maker in the gold industry today, which describes analogous landscapes and ore bodies as “Carlin-type” deposits. The Carlin Trend is a standard, in other words: a referent against which others continue to be measured.

The trend’s discovery and subsequent exploitation—and the extraordinary negative landforms that have resulted from its exhumation—has been a story of nineteenth-century US mining laws, legally dubious provisions governing public land, extraction industry multinationals, advanced geological modeling software, specialty equipment few people can name let alone operate, and genetically modified bacteria mixed into vats of gold-harvesting slurry.

Writing in 1989, John Seabrook of The New Yorker pointed out that, in the previous eight years alone, more gold had been mined from the Carlin Trend “than came out of any of the bonanzas that feature so prominently in our national mythology, including the California bonanza of 1849.”^[2] In eight years alone. And that’s because gold in the region is all but ubiquitous, peppered and snaked throughout Nevada:

There is gold in the Battle Mountain Formation, the range that runs southeast of town; gold in the alluvium to the west; gold in the Black Rock Desert to the northwest; gold in the Sheep Creek Range and in the Tuscarora Mountains to the northeast. The Tuscaroras are especially rich. Along the Carlin Trend, a forty-mile stretch of this range, are twelve deposits. Some people believe that a much richer swatch of ore, a deposit to rival South Africa’s Gold Reef, runs unbroken under the Carlin Trend, perhaps three thousand feet down—more than three times as deep as the deepest mines there now go.
