Is it just me or does the volume drop just after the intro of this song??

Hey everyone! I realized I became quite a bit more efficient than the guide on the OSRS Wiki and a couple video guides that were on YouTube. So, I decided to waste some XP and work on this guide for the few fellow Blast Miners out there and to hopefully make the activity more approachable for other miners who are curious about trying it.

EDIT: TL;DR by popular demand! https://youtu.be/4gPypVN80H8

If done right, this guide should yield about somewhere between 25-30% more in terms of XP and GP per hour as compared to the wiki guide! *AT 93 MINING!!!
My setup may differ from yours due to availability of items or stats being better or worse, but at the very least I highly recommend Level 55 Prayer for Preserve to get the most out of your Dragon Pick Spec, as the boost will decay much slower.

Let's begin!

First image is of the Northeast corner annotated with my route...

It looks like a lot, but if you can count to 8 and follow arrows, you'll be alright!

Start at the "1 & 2" corner space and progress...

IMPORTANT:
At the end of your first lap (Space 8) is when you will run back to the start (Space 1&2).
It's essential to start picking up the blasted ore that spawned previously during your first lap when proceeding through the spaces again.

You will end with picking up your 15th Blasted Ore, lighting the fuse on your 23rd (last) dynamite on Space 7 (annotated as "(23rd)" in purple on the image), then running to the sack to make your First Deposit.

(Don't make the mistake of accidentally trying to continue the loop at Space 8!)

Make your First Deposit to the sack, THEN run to pick up the 8 remaining Blasted Ore starting at Space 1&2!

Now, progress through the pick up as you would normally (follow the blue arrows) and if you did the run correctly, it should be:
1&2 - (2 ore)
7 - (1 ore)
3&4 - (2 ore)
5&6 - (2 ore)
8 - (1 ore)

Now take the 8 ore to make the second deposit and go bank to complete the loop!

What makes this method so much better?
There is a hard limit of 24 Blasted Ore that can be on the ground, if you even excavate another wall, it will overflow the Blast Mine mini-game's "array" and will discard the remainder because it hits the limit, thus making your first two blasted ore almost immediately disintegrate!
Also, Blasted Ore can remain on the ground for 3 minutes (previously 1 minute before an update).
To bypass this timer, we deposit the first batch of ores before they timeout.
This then creates a significant gap for the timeout of the remaining Blasted Ore making less of a need to rush, especially when in conjunction with the picking up of ore as you go through the cycle after your first lap.
Because of this significant gap and the amount of dynamite (23), you're plenty safe to make both deposits without too much rush or worry of the timer running out.
Creating this buffer on the timer makes the whole process a lot less intense, and once you're familiar with the route it makes doing this for hours less taxing, which in my opinion makes it even more efficient!

If you messed up at all during the loop, simply exclude the last dynamite (23rd) to give you an even greater amount of time to make the first deposit and come back to pick up the remainder!

You can use the noted dynamite to immediately withdraw more dynamite for your next loop!
Prayer potion and Stamina potions are recommended to extend your run indefinitely when banking...

What's important here and why?

Holy Symbol and Broodoo Shield
+13 Prayer Bonus to reduce prayer points drain.
Grace Cape
-4kg Weight Reduction to reduce stamina drain.
Celestial Ring (charge is irrelevant)
+4 invisible Mining Stat Boost.
Dragon Pickaxe
+3 visible Mining Stat Boost stacks with previous boost and the Blast Mine boost.

Prospector's Outfit - INSANELY IMPORTANT!!!
Before you go to the other dwarf woman to collect all of your ore, make sure to be wearing your Full Prospector's Outfit for the 2.5% bonus. This could be the difference between 100,000xp vs 97,500xp.

TIPS:
For those who haven't blast mined before...

If you didn't already know, Blast Mine enables you to mine 10 Levels above your current level, giving you access to Runite Ore much faster!

How to Blast Mine safely every time:
Always plant both of the explosives before lighting them to avoid damage.
For example: for the first corner, use your chisel to excavate the first wall and plant your dynamite. Do the same for the other wall, then light both of them. Run to the next space!

DISCLAIMER:
The numbers stated in the title of this guide are approximate, Your Mileage May Vary!
I haven't done extensive measuring. What I have done is, over time created estimates through basic timings, calculations, and stats available on the wiki.
I would love it if someone with the time would help me make this guide more accurate!

If there are better guides, feel free to point me to them!

I did my best on making this guide to be legible and maximize clarity!
This is my first guide for OSRS so be nice... 😅

Thanks for reading!
