| Promissory Notes | Notes Payable – Series I |
| In April and May, 2013, the Company entered into note agreements with shareholders in the principal amount of $1,495,000, of which $340,000 was then converted to Series B Preferred shares within the same year, netting to proceeds of $1,155,000 (the “Series I Notes” Series I). The Series I Notes bear simple interest at twelve and a half percent (12.5%), accrued interest for twelve months, and with the accrued interest to be added to the principal, and then interest to be paid by the Company, quarterly in arrears. The holders of the Series I Notes (in aggregate) are also entitled to receive ten percent (10%) of the net profits received by the Company, and generated from the bulk sampling material (if any, and up to fifty thousand tonnes) processed through the existing, or improved mill facilities at San Jose de Gracia. Such net profits (if any) are to be calculated after deducting all expenses related to the processing of the bulk sample material, and after a prior deduction of thirty three percent (33%) from the profits, to be deposited in a sinking fund cash reserve. This net profit percentage (if any) would be paid quarterly in arrears based on the profits generated (if any) for the prior quarter. At the time of the Series I Notes, there were no proven or probable reserves and the Company had not produced any net profits. Consequently, the fair value of the net profits interest on the date of the Series I Note was deemed to be zero. Further, no payments have been made under the terms of this codicil. The Notes originally matured on December 31, 2015. In April, 2015, the notes were extended to December 31, 2016. |
| The Company has the right to prepay the Series I Notes with a ten percent (10%) penalty. The notes are secured by the Company’s stock at $5 per share. |
| The Series I Note holder retains the option, at any time prior to maturity or prepayment, to convert any unpaid principal and accrued interest into Common Stock at $5.00 per share. If the Series I Note is converted into Common Stock, at the time of conversion, the holder would also receive warrants, in the same number as the number of common shares received upon conversion, to purchase additional common shares of the Company for $7.50 per share, with such warrants expiring on December 31, 2015. In 2013, the Company offered an inducement to all Series I Note holders to convert their Series I Notes and accrued interest into Series B Preferred Stock (“Series B”), $5/Share, which Series B was convertible into common stock on a 2 for 1 basis (i.e., $2.50 stock). This conversion into Series B created $197,771 in inducement expense, with an offset to additional paid in capital. In 2013, $340,000 principal and $22,734 of capitalized accrued interest of the Series I Notes were converted into Preferred Stock, Series B and 72,546 shares were issued. At June 30, 2014, these 72,546 Series B shares were converted into 145,092 common shares. |
| In April, 2015, the Company received note extensions (allonges) from all Series I note holders to ensure that all Series I Notes were in good standing and also extended the maturity date of the Series I Notes to December 31, 2016. |
| Notes Payable – Series II |
| In 2013 and 2014, the Company entered into additional note agreements of $199,808 and $250,000, respectively (the “Series II Notes”) with similar terms as the Series I notes. The Series II Notes bear simple interest at twelve and a half percent (12.5%), accrued for twelve months, and with the accrued interest to be added to the principal, and then interest will be paid by the Company, quarterly in arrears. The holders of the Series II Notes (in aggregate) are also entitled to receive ten percent (10%) of the net profits received by the Company, and generated from the bulk sampling material (if any, on the second fifty thousand tonnes) processed through the existing, or improved mill facilities at San Jose de Gracia. Such net profits (if any) are to be calculated after deducting all expenses related to the processing of the bulk sample material, and after a prior deduction of thirty three percent (33%) from the profits, to be deposited in a sinking fund cash reserve. This net profit percentage (if any) would be paid quarterly in arrears based on the profits generated (if any) for the prior quarter. At the time of the Series II notes, there were no proven or probable reserves and the Company had not produced any net profits. Consequently, the fair value of the net profits interest on the date of the Series II note was deemed to be zero. Further, no payments have been made under the terms of this codicil. The Notes mature on December 31, 2016. |
| The Company has the right to prepay the Notes with a ten percent (10%) penalty. The notes are secured by the Company’s stock at $5 per share. |
| The Note holder may, at any time prior to maturity or prepayment, convert any unpaid principal and accrued interest into common stock of the Company at $5.00 per share. At the time of conversion, the holder would receive a warrant to purchase additional common shares of the Company for $7.50 per share, such warrant expiring on December 31, 2016. |

The accrued interest for these notes was $163,702 and $109,292 as of March 31, 2015 and December 31, 2014, respectively. |
| In April, 2015, the Company received allonges (note extensions) from all noteholders to ensure that all notes were in good standing and also confirmed the maturity of the Series II notes to be December 31, 2016. |
| Other Notes Payable / Repayment |
| The Company received proceeds from a short term convertible note in the amount of $203,500 on September 5, 2014. Interest is accrued at 8% annually and interest payments are deferred until conversion or payoff of note. The note provisions allow payoff in the first 180 days subsequent to funding, with additional premium of 10% of the note amount in the 1st 30 days; 12% if paid in the next 30 days; 15% in the next 60 days; and 19% if paid before the end of 180 days. After 180 days, the note is convertible to common stock at a “variable conversion price” of 70% of the market price (average of the lowest three trading prices for the common stock during the ten trading day period ending on the latest complete trading day prior to the conversion date). This note was guaranteed by the CEO of the Company. |
| This Note was retired in full in February, 2015. Because the note was repaid within the 180 days, the option to convert was never available. Consequently, the embedded conversion feature was not bifurcated and no derivative was recorded. |
