Thank you, Tracey. Good morning and good afternoon, and welcome to the first Hycroft Mining Holding Corporation quarterly call. As probably most people on the phone are aware, on May 29, Hycroft Mining Company, a private company, completed a recapitalization using a special purpose acquisition vehicle. And as a result of that, the Hycroft Mine is now owned by Hycroft Mining Holding Corporation, a listed company on NASDAQ.
In July 2019, about a year ago, M3 Engineering, along with SRK and Hycroft Mining Corporation, completed a feasibility study for one of the world's largest precious metal deposits with a resource in excess of 31 million gold equivalent ounces. That feasibility study showed a net present value of $2.1 billion, at metal prices of $1,300 gold and $1,733 silver. Today, we see gold and silver above $2,000 an ounce and $28 an ounce, respectively. In fact, if you take Friday's spot prices -- Friday's closing spot prices of $2,035 gold, $2,832 silver, the NPV is approximately $5.6 billion.
As you would expect, a mine with a 34-year mine life is incredibly leveraged to the precious metal prices. To put that in a little bit different perspective, $100 change in gold is $300 to the NPV, and $1 change in silver is $125. To this point, the company has been putting the building blocks in place to take advantage of just such an opportunity as presents us today. We have this excellent, capital-light, permitted expansion in front of us, taking advantage of what Hycroft Mining Corporation already had in place.
Specifically last year, the owners of Hycroft Mining Corporation took the decision to restart the mine, and we began refurbishing equipment and infrastructure. We started up the crusher, replacing the four cone crushers that we knew needed to be replaced. We started mining in April and we started producing gold in August.
In order to build the future of Hycroft and continue to ramp up, we have four key focus areas: people; our mobile equipment; the process side, which includes both the crusher as well as the oxidation on the leach pads; and then the infrastructure and capital that supports that. While focusing on this initial restart and continuing to focus in the future, our goal is to maintain a high level of discipline in our health, safety, and environmental practices. Specifically this year, we've added a new safety manager and a new environmental manager.
Like most businesses, we believe the first step to success is finding the right people. Our focus in 2020 has been building a strong team with talent and knowledge to build our plants to reality. Specifically, we've increased the workforce 35% year to date. We've identified and added key management roles that we need to operate the mine. In February, we brought on a new general manager and he's quickly come up to speed on the operation, and proven to be a very effective operator.
We recently split the process manager role into two, to better -- get better focus on the key process area around the oxidation of leach pads. Specifically, we now have one process manager whose responsibility is purely technical, and that is managing the oxidation, and a second process manager who is focused on the operations and that is implementing what needs to take place. We've recently added a highly experienced HR person that's helped us to bring on some of these additional people as well as number of technical folks to our maintenance teams, both on the equipment side as well as the crushing side.
Specifically, we've found a couple of strong electrical and instrumentation technicians which are critical to maintaining the crushing system. Supporting us, we have an excellent procurement team and they've managed to put in place long-term contracts for our soda ash, our lime and our cyanide, our three primary reagents. Today, we have a complement of 216 employees. And as we continue to grow our manpower, we have a goal of 275 employees by the end of the year.
On the mining side, we've improved our mobile equipment maintenance team to transition to self-perform maintenance and begin to discontinue the contractor-led maintenance that we've relied on since start-up. That's part of the increase in manpower overall as we're trying to wean ourselves from relying on contractors, bringing that expertise in-house, and then developing it further so that we maintain the expertise long term.
In April, we increased our mining fleet through the rental of seven 240-ton haul trucks and a loader that replaced a smaller fleet that we had with a contractor. Net, overall, that more than doubles the number of trucks that we have. We own six 200-ton trucks in addition to the seven under rental.
On mining, we started out in stockpiles. We're now actively drilling and blasting in pit. Overall, we've increased our monthly mining rate from January to June by 55%.
Moving downstream to the crusher. The crusher was really the focus of 2019 and into early 2020. The crusher had sat for several years. As I mentioned, we had to replace the cone crushers, which we knew before startup, and it took us a while to get that crusher up and operating efficiently. We've seen significant improvement in the first quarter. We averaged 338,000 tons through the crusher, and in the second quarter, 459,000 tons. Part of the reason for that improvement is we've put in place a comprehensive preventative maintenance program. We've added a trainer on site to do operating training.
The crusher is designed to be run in an automatic mode, and the only way to truly do that is to have very knowledgeable operators. And we've seen huge improvement on the operator side in the last few months. We continue to improve the crusher, and we have plans in the fourth quarter to further upgrade the automation and process controls; improve the overall electrical infrastructure; and perform a final OEM review with FL Schmidt, who is the manufacturer of the crushers, to prepare to step up the tonnage in 2021. Once the ore is crushed and it's moved out to the leach pads, we're focused on oxidation.
The most important thing we've done to date is for test pads one and two, the initial two pads that we stacked out there. We've been able to show that we can actually, in a true commercial setting, obtain recoveries greater than the feasibility level. Specifically on test pad one for the Brimstone, which represents 80% of our reserves, we achieved a recovery level of 82% versus what's in the feasibility of 65%.
On the second initial pad, which is Central ore, which is 19% of our reserves, we achieved a recovery of 91% versus 70% in the feasibility study, demonstrating that we can, indeed, in a commercial setting, get the recoveries that we've identified in the feasibility study.
We've also improved the solution management system -- what we call the reagent island -- that increases the solution distribution to our leach pads. When we initially started up, it was a little bit undersized and we needed to increase that size so that we could properly manage all the leach pads as we continue to stack out onto the leach pads.
In terms of the reagent island itself, we've got further improvements online for the third quarter. We're going to add new tankage with an agitator that will allow us to better dissolve the soda ash into solution which will improve the kinetics in the leach pad, specifically increasing the oxidation results and increasing the pH so that we're seeing better overall recoveries.
If we move further downstream to the process, the actual processing of the solution flows once we put them under leach. We've got the infrastructure in place to be able to ramp up our operations. We're currently operating the Brimstone Merrill-Crowe facility and refinery. We've added carbon columns or a CIC circuit to capture metal from a low-grade solution. And we've begun planning the restart of the 21,500 gallon per minute North Merrill-Crowe plant, which we'll utilize later on in 2021 when our solution flows achieve about 9,000 gallons per minute. Currently, we're at about 5,000 gallons per minute.
We've set our second-half targets for mining, crushing and oxidation at levels we believe that can be successfully achieved and further demonstrate the success of our two-stage oxidation and leach process. We expect the second-half crushing and production levels to be consistent with or a little bit above our first-half levels. And our focus is on getting prepared for ramping up mining, crushing, and production in 2021 with the new leach pad and space in place.
We've made significant progress on the new leach pad. That new leach pad -- the first phase is 4 million square feet, along with the necessary ponds, pipe and electricity that will be required to operate that new pad. That new pad is critical to our ability to ramp up. We've spent $9.7 million through June on the new leach pad, and we would expect to spend about $36 million in total. And we would expect in the fourth quarter to begin stacking on a new leach pad.
We did have some struggles in the second quarter related to leach pad processing activities which resulted in the write off of about 6,500 ounces of gold. We did not properly execute our processing plants and had delays in getting our pads under leach. This is directly a result of a lack of manpower, specifically at the manager level, and the undersized reagent island that I mentioned.
With the addition of manpower that we've made now specifically around processing, we believe we have the team in place, the two managers that I already discussed, as well as a senior metallurgical engineer. And we believe we can execute our plans properly moving forward.
To enable us to be in position for the ramp-up in 2021, we've begun the process of speaking with financial advisors and stakeholders about options and timing related to securing additional financing.
Additionally, we've received a letter of support from our two largest stakeholders -- that is Mudrick and Whitebox -- and that letter was filed this morning in our 10-Q as an exhibit. The Board of the company intends to evaluate our options to ensure the necessary capital is raised on terms favorable to and in the best interest of all its shareholders.
We have no commitment at this time, but as I said, we've begun work with our financial advisors and stakeholders about potential options. We're very excited about the improvements we've made to date. We're excited about those planned for the second half of the year, and really excited about getting ourselves to the place where we can significantly begin the ramp up of crushing mining, crushing oxidizing, and ultimately production in 2021.
The new leach pads are key to us being able to do that, and it's exciting to go out there and see the progress that's already been made on those. We look forward to updating everybody on future calls of continued progress. If you have any questions about the quarter, please contact Tracey Thom. Her contact details are on the website. Want to thank everyone, and we look forward to updating you in the future.
