Cyanide… a discussion on ways to ban its use, and thus halt large scale metallic mining

Apr 7, 2023 | Gold Mining

The effort at the state level to ban cyanide use in mining was at first very well received. But partisan actions killed it in committee, halting any further possibilities in the 2023 General Assembly to protect us from potential metallic mining. We recently discovered that Virginia law would support this at the local level.

Revisiting the ban on the processes that use cyanide in metallic mining may be the most agreeable way to halt large scale mining at the local level. It was suggested by Supervisor Danny Allan, and again by gold miner Paul Busch, as the way to get around the problems that arise with a ban on metallic mining.

Because we live in a strongly followed Dillon Rule state, localities activities are limited by state pre-emption. But! We found Virginia Code that allows localities to prohibit mining. And, we just found out that VA Code 15.2-2280, not only allows localities to adopt bans on mining but also allows for restrictions. So: “…it may regulate, restrict, permit, prohibit, and determine the excavation or mining of soil or other natural resources”. So the County can have a say in how extractive activities are done.

We have long awaited: Southern Environmental Law Center (SELC) has just published their 10 page Toolkit for communities to better understand the land use tools available to regulate, restrict, or prohibit mining activities. To visit their gold mining page click Here. Click on Resources for the Toolkit.

We have options to:

  1. ban metallic mining, or
  2. ban the metallic mining process using cyanide,
  3. and/or adopt the rights-based Prove It First ordinance.

Here is information on cyanide bans. First, see the simple language of the failed Virginia House Bill 1722. Then the simple language of the successful Montana cyanide ban law – not much difference. And some commentary below.

Industry claims cyanide is relatively safe because—even if it spills—it breaks down rapidly in surface water.

But the compounds that cyanide breaks down into can be harmful.

Cyanide spills into groundwater can persist for long periods of time and contaminate drinking water aquifers.  Cyanide contaminated groundwater can also pollute hydrologically connected neighboring streams.

Cyanide’s efficiency makes mining more wasteful
Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades.

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are:

  • much larger than before cyanide was used;
  • create vast open pits; and
  • produce huge quantities of waste.
  • More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
