>>high heat
500°C isn't even hot enough to melt aluminum.

>>pressure
we have robots and submarines that can withstand 1070 atm of pressure, pressure really isn't much of an issue.

Temperature is a bigger issue because actuators are more difficult as magnets don't work very well at these temperatures and traditional semiconductors stop working above 300°C.

First has largely been solved and electric drills have been tested in Venusian ambient: http://www.lpi.usra.edu/vexag/may2008/presentations/22JIExtreme.pdf

Second, basic silicon carbide semiconductor technology has been demonstrated to work at venusian conditions. A SiC ring oscillator worked fine for 21 days(as long as they were willing to run the test) at venusian ambient conditions.

>>mine resources with surface rock that's like taffy due to the heat
Bullshit. Nothing from the Venera probes indicates that rock on venus' surface behaves like taffy:

>>using what kind of rocket?
balloons. A metal bellows balloon(pic related) can reach altitudes where plastic doesn't melt, from there a teflon coated(to resist the sulfuric acid clouds) kapton balloon can be used to reach ~55 km which is about the altitude our colony would be at.
