What happened to Virginia city after comstock discovered silver ore in six-mile canyon?

In PA a city that is 43 degrees north and 79 degrees west?

This question has a couple of interesting aspects to mention ...1). Once you state latitude and longitude, you've already pinned the location downto within less than 100 feet of some point on earth. No other information, such as"in PA", is necessary.2). Having said that, the point specified in the question is not in PA. It's in the stateof New York, on Grand Island, down river from Niagara Falls.To put a finer point on it, this location is 1,550 ft north of Love Road, 3,850 ft west of Sixmile Creek, and 4,980 ft east of W. River Rd., on Grand Island, NY.
