Based on standard option pricing arguments and assumptions (including no convenience yield and sustainable property rights), we will not observe operating gold mines. We find that asymmetric information on the reserves in the gold mine is a necessary and sufficient condition for the existence of operating gold mines.

Mining for Gold (and Platinum)
Proceedings of the 2016 Annual Symposium on Computer-Human Interaction in Play, 2016Achievements are a common feature of modern video games. Early research efforts have attempted to classify achievements into taxonomies in order to identify achievement types and to learn about their potential affect on players, however, these studies have been constrained by small, manually collected samples of player data.

The Economics of Gold and Gold Mining
1987Gold mining and placering reach back into antiquity to a time at least more than 4,000 years before our era. During primitive times the winning of gold was a haphazard activity, nuggets of the native metal being plucked from some auriferous stream, the oxidation zones of gold or sulfide deposits, or from residuum near such deposits.

Cats: A Gold Mine for Ophthalmology
Annual Review of Animal Biosciences, 2013Over 200 hereditary diseases have been identified and reported in the cat, several of which affect the eye, with homology to human hereditary disease. Compared with traditional murine models, the cat demonstrates more features in common with humans, including many anatomic and physiologic similarities, longer life span, increased size, and a ...

Green Gold - A Gold Mining Perspective
SSRN Electronic Journal, 2019Gold is a long-lasting, durable and thus sustainable metal and asset. However, mining for gold often adversely affects the environment. This study proposes an alternative to mitigate these negative externalities and costs of gold mining. Instead of digging out gold for investment purposes we propose to leave it in the ground and let nature act as a ...

Azadirachtin, a scientific gold mine
Bioorganic & Medicinal Chemistry, 2009Azadirachtin is a highly interesting compound both for its chemical structure, which required 18 years to solve, and its synthesis, which required another 22 years, and for its biological properties as a feeding deterrent for many insects and a growth disruptant for most insects and many other arthropods.
