Welcome to the mindat.org media viewer. Here is a quick guide to some of the options available to you. Different controls are available depending on the type of media being shown (photo, video, animation, 3d image)

Controls - all media types

Zoom in and out of media using your mousewheel or with a two-finger 'resize' action on a touch device.

Use the mouse or your finger to drag the image or the view area of the image around the screen.

< and > at the left and right hand side of the screen move forwards and backwards for the other images associated with the media you selected. Usually this is for further photos of the same specimen. Keyboard shortcuts: use the left and right arrow keys.

> in the bottom center, raises the information box giving details and further options for the media, < at the top of this box then hides it. Keyboard shortcuts: use the up and down arrow keys.

Controls - Video

Video files have a standard set of video controls: - Reset to start, - Skip back, - Play, - Pause, - Skip forwards. Keyboard shortcuts: You can stop/start video play with the P key.

Controls - Animation (Spin Rotation)

Animation (usually 360 degree spin rotations) have their own controls: - enable spin mode. Note that while images are loading this option will not be available but will be automatically activated when the animation has loaded. Once active you can spin the image/change the animation by moving your mouse or finger on the image left/right or by pressing the [ or ] keys.

The button switches to move mode so that you can use your mouse/fingers to move the image around the screen as with other media types.

The button, or the P key will start playing the animation directly, you can interrupt this by using the mouse or finger on the image to regain manual movement control.

Controls - 3D Stereoscopic images

Stereoscopic 3D image viewing requires a suitable 3D television or monitor correctly configured for your computer. Passive 3D systems such as LG 3DTVs are the easiest to configure for this.

To enable/disable 3D stereo display of a compatible stereo pair image press the 3 key. If the left/right images are reversed on your display (this often happens in full-screen mode) press the 4 key to reverse them.

A gift from The Goldfield Consolidated Mines Company.

This amazing “Loving Cup” was specially commissioned for John H. Mackenzie, a well liked and loyal manager of the Goldfield Consolidated Mines Company. Mackenzie was respected not only by the companies owners, but by the men that were employed under him. In 1910, Mackenzie wanted to go into the services, so he made it known that he was going. The owners of the company had the premiere silver and Gold Smiths at Shreve in San Francisco to estimate how much Gold they needed to make a Loving cup as a gift for the great years of professional service that he gave. Shreve said that the cup would need 75 ounces of Gold to make, Nixon & Wingfield used the Gold from the Mohawk, Red Top, Jumbo and Combination Mines. They also had their Consolidated Mill smelt the Gold down to a high purity. The result is this original photograph from 1910 showing the Loving cup. It would have a todays value of over $90,000 in scrap Gold!! No one knows where the cup is now, it could have been melted down during the hard times of the Depression era of 1929 - 1934.
