Jagex has not offerred new quests to non-members on a continuing basis. The last quest to be offered to both members and non-members alike was the Rune Mysteries quest.

When you are a level 3 player with the ability to mine essence, hop to it. The only thing you will need is a pick axe to mine the essence. Bring nothing with you except for your pickaxe (the highest level pickaxe you can yield). Don't bring food, and don't wear . This will only slow you down. If you have completed most or finished the Temple of Ikov Quest, then be sure to wear your boots of lightness. With just a pickaxe wielded, a full load of essence, and the boots of lightness on, you will have a weight of -2 kg. This will allow you to run longer and carry the maximum amount of essence that you possibly can.

Go to the Rune shop in Varrock, talk to Aubry, and be teleported to the essence mine fields. Mine the essence from the rocks until you are full. Run back to the Varrock bank west and deposit your essence. Once you have around 1,000 essence go to Varrock Bank west and announce that you are ?selling 1k of ess?. People will offer you anywhere from 30k to 50k depending on your negotiation skills (35-40k is a fair price and you should go with it if you are offered it). Always go to world 1 to sell your runes or world 2 if you are a member. Members will usually offer more for essences, but if you are not a member and can only get on world 1 be patient and you will sell them for a nice price. You will always get a higher gp per essence the larger the amount is that you are selling. It should take you around 10 minutes to mine 200 essence with a decent pickaxe and a set up like I have described above. With a low level pickaxe it will take a bit longer. We will use an example of only getting 200 essence every 10 minutes instead of every 5 minutes. A little over ? million money is the results of your efforts of mining 12 hours.
